- เผยแพร่เมื่อ 27 เม.ย. 2024
- Today on christmas3dp, we're taking a look at the recent patent claim that the VzBot Goliath 3D Printing Hotend has been involved with. Slice Engineering, creator of the Mosquito hotend has patented a large amount of things about it, including their spacer technology. The VzBot Goliath apparently infringes this patent and was taken down by Slice Engineering. The communtiy thinks otherwise however - and today, we're breaking down on Slice Engineering's Statement on Intellectual Property (IP) they posted on their blog. Enjoy!
Special thanks to 14.4mL for the awesome music found in the intro.

I have passed through all kinds of feeling throughout this saga..from sadness and tears, to anger and madness and discouragement even to a point of abandonning the Goliath project entirely and maybe the entire Vz world. I didn't want a fight with anyone. I never thought it would have been like that (maybe I live in a unicorn world where everyone loves each other...). All I wanted was to bring a good high performance hotend at a very decent price so everyone could afford it. But I am not a quitter. I won't stop! I will not stop doing what makes me happy in life. I will not let this patent thing stop me. Goliath will live and no matter what it takes. Please don't be too hard on Slice for this. Busyness is busyness and they did what they had to do. I will repeat what I said I facebokk here: Dan and Chris are still very good persons and this was not something personal to me I know. Busyness is cruel sometimes but it is what it is though I don't agree with this patent. And trust me I am not against patent in general. I would still go for a beer with those guys and discuss like 3d passionate people do. For now, I am just waiting on Covid lock down to end in China to release the Goliath with a patent friendly update. Thanks for this well done video my friend. It made my day and got my heart warm and gave me a good boost of energy to go on!! Love you all guys!
I don't know what I'd do without your VzBot movement nowadays. Having built two VzBots when the project just started out myself has taught me so much and made me create many exciting and fun mods, even my own 3d printer project! Thanks for staying strong Vez and building this great project for all of us. I'm glad you enjoyed it. Keep going and never stop, we're all with you!
Please don't stop vzbot it is probably one of the best, fastest, and quality corexy printer I have seen that can rival prosumer even professional printers on the market. I look forward to building a vzbot soon with the extruder and Goliath hotend if it wasn't for already owning a v-minion I would have had a vzbot 235 already lol keep up the great work and keep innovating. Slice engineering guys might be cool guys but this was still a messed.up move
Persevere and prove to all the uninitiated that patents don't kill innovation. Stay strong.
You're a better man then I, personally I find the whole patent thing being used like this going so against everything I love about open source printers and hardware and the community in general. I'm glad you're able to find ways around this crazy stuff. Hang in there man.
Excellent response! Hopefully you can continue on and become bigger and better than ever! I don't totally blame them personally either BUT greed is ugly :(
I suspect that the only reason they did not patented the Bimetal heatbreak is not because of the goodness of their heart but simply it will not fly with the patent office. Hotend are inherently bimetal on both end. They simply move the interface from one part to another
Yep. I mentioned this as well. Their IP model seems more like: Patent if possible, if not, make a big name out of findings and call others copycats anyways.
Agreed, its thermal dynamics not a patent and in real extrusion long before 3d printing heat breaks are used still today to extruder polymers no new tech and bolts aren't special to just them, the fact they have one for this is discussing and degrading to every RED seal millwright 100% and more
Having seen this video I would even argue that Slice Engineering's patent should be invalidated since it has been done before and hence simply can not be their IP.
agreed. nearly a decade before they came along - it was already done - because the concept of 'keeping the hot making parts separated from the parts that need to be kept cold" was not that hard to figure out , even in early days.
Literal definition of patent trolling. You find a method that already exists but is not patented, combine it with your product with just enough (if any) new design features to get a patent granted, then you bully competition (usually smaller fish) into submission by legal threats. Slice can't go against Creality for MK8 hotend despite the same spacer design, because Creality has the means to fight in court, and possibly invalidate the patent. Smaller fish like an Aliexpress seller/manufacturer or a design group like Vzbot or Voron = easy to shut down because they can't afford to go to court. IP laws are stupid like that, and rectification can be done through legal means but not all parties have the means to challenge it, smaller fish just has to capitulate and shut shop. Same with RED for example in camera business, they usually go after 3rd party accessory makers instead of Panasonic or Canon (but they've tried that too).
this wh< the whole patent system is garbage....look at what is currently patented - its utter lunacy. Prior art is what makes humans evolve. Patents undo that by protecting stuff as new when it really is prior art..
Maybe if everyone keeps letting Slice know forever that their patent on spacers is ridiculous they will cave eventually.. I am..
Yeah! Make sure to share the video around if possible. We gotta get this message out!
No use having a patent on something no one will buy.....😎
yeah lets go boycott slice😂
I almost bought Slice's bimetal heat break, but now I'm glad I bought a different brand. IP supposedly rewards innovation, but it only punishes those who improve upon previous innovations. If you want to be rewarded for your product in a supposedly free market, you should have to make it appealing with good quality at an affordable price, and innovation can be part of that. Patents are a license to produce poor quality products at a high price because customers can't get better from anyone else. That's a monopoly.
Here before the youtube algorithm rightfully makes this vid viral
Nice video. It would be good to dig up prior art, there were spacer isolated hotends before Slice came along, so their patent is probably invalid. It takes lawyers and money to fully attack a patent but digging up and sharing the old evidence through the community would go a long way to help getting Slice to back off. They apparently reinvented an old wheel and got unearned credit for it.
Sharing it will also point out the hypocrisy in those youtubers that claim to be against patent trolls but still accept money from Slice Engineering.
Honestly if someone digs something up and would start a kickstarter campaign for a lawsuit I would probably donate.
@@Di3Leberwurst same for me, I'd donate!
See my comment.
The example above (Plastruder MK5) your comment looks similar in concept to what the Mosquito is doing
Would never buy a slice hotend. Way to expensive & i don't like companies that act like this. It is a no go.
Recently bought an E3D Revo hotend. Good quality for way lower price.
Slice is only afraid of others making better products for lower price. 🙄
I'm glad you like the Revo! I'm making a video about it, too, soon :)
The Revo is awesome. I might be in the minority, but I fucking hate nozzle changes. No matter what I do, something always goes wrong during a nozzle change with wrenches. Filament leaks, damaged the heater cartridge and thermistor on my Prusa Mini during nozzle changes (really poor design there, tbh), etc. Revo system is the solution to all that bullshit.
Lower price, yes... better, largely no.
REVO ALL THE WAY BABY
Revo has a patent too. That said it's a bit different than slice. I don't think you should be allowed to patent standoffs. Standoffs are used in everything for isolation and rigidity. Maybe you can patent the way you implement them say how they use surgical tubing to better insulate the heat.
The real bad guys here are the patent office who should not have granted it in the first place
Final nail in Slice Engineering's coffin for me. I have never liked their Mosquito patent because as shown in this video it is both obvious solution to the problem and it has ben done before by others. In this I have always seen it similar to Apple patenting a generic sketch of a touchpad decades after the same device featured i movies and literatrue, after Star Trek had it in hundreds of episodes. It is just ridiculous to me that such patents even get granted.
Nevertheless based on some reviews I bought a Copperhead hotend once. No clones, I do not trust cheap clones, I wanted the genuine article. I have never been more disappointed by a hotend's performance before or since. And I have never had a 3D printer component that would be so overpriced for what it is.
Slice Engineering has the business it has because in 2009 some patents expired and open source community took over the developement. Prusa could only start selling printers after they were no longer blocked by patents. So for Slice to use patents now to block others that do not just straight up clone them but just use one tiny similar part in an otherwise completely new and unique design is just making me angry. So angry Slice will never get a cent of my money no matter what they make. I will not buy anything from them even if it is twice as good as anything else on the market. I would rather suffer worse performance than support these people. And I will try to convince others to do the same whenever someone asks me for advice on printers.
Spreading the word is our most powerful tool and our most important responsibility. I would feel awful if I bought a product from them and then found out what I was inadvertently supporting.
This. That's why I'm opening my own 3d printing store with brand new and innovative products myself. Hope to make innovation affordable and open for anybody
his points on the uniqueness is on point.
one could argue that the hotends A, B and K show prior art, as well as show their claims are not new.
THAT IS GROUNDS FOR A PATENT REVOKATION
If prior art or publications show that your claims are not new, the USPTO may invalidate, or revoke, your patent
you would just need a lawyer to write a re-examination request, and I bet that there is likely at least one company looking into that, for how wide their patent is
Neither of those designs is covered by the patent that Slice engineering has. The patent does NOT cover standoffs, it covers specifically standoffs that are kept in compression by a separate tensioned member (like a screw).
@@erikcederb yep, and at least partially reduces mechanical loading on the feed tube. I sent vez the full patent history a couple of weeks back and highlighted the prior art they successfully argued around. (
Doesn't the... ender 3 use screw/spacers to keep the hotend from twisting off the cold end?...
the video shows it in 13:03
I'm sure many others will feel the same as me, because of how slice engineering is anti-competitive and sue-happy I will out of principle never buy a product from them and also will actively discourage others from purchasing their products. With this in mind their circle diagram fails because customer resistance to bullying tactics and because the companies who have had their products removed have no recourse against this bullying I will actively try and support them with my money.
this is difficult, 10 year long or whatever patent period is way too long for current rate of development, imagine what tech we would have now if all 3d printer tech was open
I don't get that patent could be granted. My Ender 3 hotend used 2 extra bolts for stability way before there was any Slice engineering hotend. That is clearly prior use, no? So is using 4 screws unique? Well, then we can just use 3 or 5 to bypass the patent.
From my very limited knowledge of patent law, it’s mainly about having the money and time to challenge and defend your patents. You can kinda see how open source projects have a distinct disadvantage in this regard.
Don’t buy slice products and like the VORON team, remove support for them in your open source projects.
Would that be enough to get around the patent?
The patent is around making the heatbreak non structural by the means of having something else in compression and something in tension. In the case of the Creality hotend you have two screws in tension, and the heatbreak in compression. Clearly the Slice setup is better, but you can easily dodge the patent going the Creality route using screws without spacers, it is what Rapido and Dragon UHF do.
Goliath only use 3 screws as well but they still went for it
Fun note - if you pm triangle labs directly, they might still sell the clone mosquito
ive said this from the start about slice engineerings patents, the parts that make up the mosquito arent really new as a concept, like this "spacer technology" yet the Ender 3/CR10 hotend uses 2 small screws on either side for much the same reason. and not to mention bimetalic heatbreaks arent really new, just finally in a pacakge thats not a diy hack job. heres one example of someone inventing one back in 2012 on reprap forums thread ID 1,250849 just no one called them bi metalic heatbreakss. it was a diy "stainless steel hypodermic tube" soldered directly into a cooper heater block and a "copper tube" with water running through it to keep it cool. this is so old that the nozzle is made from a dome nut. i argued with Design Prototype Test a while back about this, both these points
Super interesting! I'll have a look
Y'know I was a bit confused because I saw the exact configuration on my Ender 3... when I was installing one of Slice Engineering's bimetal heat breaks on it. Shame, too - it worked really well and fixed issues I had with plastic melting and clogging the system.
I probably wouldn't have even known that Slice had some marginally-inventive patents in their portfolio if they hadn't written such a weirdly vindictive blog post that pulls the whole "Open Source is communism" nonsense
@@SuperSmashDolls while they have made inovations ontop of what prior art they are now going after other hotends that are not even copying their designs.
The Vzbot goliath should never been taken down. how they are isolating and supporting the heater block is unique, 3 screws inside the ceramic spaces. slice has 4 seperate thin walled spaces and 2 cr10 style exposed screws.
if they are able to take down the goliath hotend then their patents are far too encompassing. the nfcrazy and spider were justified to take down but not the goliath. someone needs to just call their bluff and get their patents stripped at this point. by the sounds of their patent either they essentially patented the use of washers. or the CR10 also infringes on their patent.
by the sounds of it at least vzbot would only need to remove the spacers leaving bare screws holding the hotend in place. just like the CR10 with 3 screws.
they made that blog post to convince themselves they are the "good guys" in this whole ordeal. they could have had some specific patents but they got greedy and tried to make their patent far too broad. i hope it comes back to bite them
Screw Slice, i will never buy anything from those patent trolls.
All they are doing is annoying and holding back the 3d printing community like Stratasys did back in the days.
Hopefully there will be massive pushback from the community at some point if they keep this up, forcing them to go bankrupt.
Same. I wouldn't even call my feelings hate, I just wish there were no ppl like this. I wish them the worst, for good of everyone else.
Just my two cents worth - about 8 years ago built a hotend that essentially used a V6 cold end with 3 long tube spacers bolted to the hot end and running up through the fins to the top flange to test the idea out. Similar to some of the old units you showed. It was effective but never carried on with the design. Slice engineering patent does not really show that much innovation over some of the prior art, they just managed to get a patent on this aspect of hotends first. One thing to understand in the US if I remember correctly it doesn't matter who invents first - it is who publish or patents first. Surprised they didn't try to patent copper hotends. One unfortunate upshot is they are aggressive in defense of their patent, which is their gig if they want too. There are other products on the market....or do like me make you own.
I'm sure there are numerous people that also used spacers in their diy hotends; it is simply the most obvious design.
"It doesn't matter who invents first - it is who publish or patents first."
The key word here being "publish", as that is not limited to patent submissions. Whenever it can be shown, as here, that a design has been published in any medium or by any party - even the party later submitting the patent request - prior to a patent being granted, US patent law requires the patent being requested to be declared insubmissible and invalid to be granted. When this prior publishing is brought to the attention of the US Patent and Trademark Office after a patent has already been granted, usually but not always by way of the court system, US Patent Law requires the patent in question to be revoked. This is a separate sticking point from those laws which likewise declare invalid any patent whose design is identical or "not significantly unique from" prior existing patents even in other industries, as well as any patent on material composition. Unfortunately, patents fitting each of these disqualifying criteria often slip through because of the volume of requests and limited personnel available to review them and are difficult to actually get revoked because of the many court decisions and contracts expanding arbitration well outside of the boundaries explicitly written into the relevant act, and because so few people have formal training in locating prior art in either digital or traditional media, complicated by the fact that if said art was originally published online many patent trolls direct their first takedown requests at the entities hosting it and those often do not dare reject those requests under any circumstances.
This is one of those features that honestly shouldn't be patented, like having images play on loading screens between game areas, which is also ridiculously patented.
And thinking Vez 3D did reviews for the Modquito Magnum + and gave discount codes…
Isn’t it the case that the European Union Patent system does not acknowledge the slice patent?
I was quite baffled how emotional slice response was.
Shame, insult, guilt.
After some years on this planet people can smell the BS when they use defensive tactics like Gulag topic, Veteran support, accusations and downplay of „their need to protect their financial interest“
If they were in the right, non of these would be arguments worth considering to convince all of us „Communists“ to get on their side.
Agree with you fully, if Slice would be less hostile to the community many would be in their support.
Slice makes awesome hardware (own two hotends) but consciously hindering innovation with a patent that can instantly disqualified just by looking at the mentioned hotends from 2014, just goes too far.
I feel very similar! Great to hear I'm not the only one. Thanks for watching
If that's the case, the business address for this hotend should be in Europe. Skip all the bullshit.
@@AllTheNamesWereInUse can you elaborate on this?
Like the business address every web page store has for their headquarters?
This whole veteran and commie talk is just a sample of American conservatism.
@@middleagebrotips3454 maybe that's why this discussion always has a few bootlickers, acting ideologically and spewing journalistic drivel about this very clear issue.
Thinking that nothing needs to change to get better isn't an ideology; it's fear, ignorance and stupidity. They trick themselves into thinking that their side of politics is ideologically consistent on this issue, when no side of politics ever has been; especially in the US.
I hope they realize that taking down the "clones" on AliExpress not only does absolutely nothing for the 3D printing community, but are still available on TaoBao (AliExpress is the international version of TaoBao).
So basically the Chinese went: "Oh, we can't sell on AliExpress? We'll just keep selling it domestically, not like you can do anything about it"
So what you have done is locked the rest of the world (at least those who don't know how to buy from TaoBao) out of new, innovative Hot-ends that are way cheaper while the Chinese can enjoy them all to their selves. Really doing your country a favor by losing out more to China.
Didnt my first creality ender 3 have standoffs on the hotend? Sure its been modified so I don't have the original hotend anymore. but I thought that was before slice? How can you patent something already in existence?
Patenting 4 screws is the definition of patent trolling. They should be sued because they stolen ideeas from the community and they now use it to make money
For those raising points about E3D patenting the Revo hotend, there's a big difference here. Slice is holding patents hostage and preventing people from using the idea of rigid spacers between the hot and cold ends of a hotend, while E3D is only patenting to prevent exact clones of Revo. There's a stark contrast here. The E3D patent only protects the looks of the Revo, and doesn't stop anyone from making a separate hotend that supports swapping out the nozzle and heater when cold. This helps stop cheap low-quality clones from flooding the market while not inhibiting others from creating products that derive from this core idea. That's a much better way to do patents.
i wonder what it takes to invalidate a patent, their pillar/standoff patent is outrages as in there were prior arts. they are by definition, a patent troll.
Same! It's been publicized and done way before, could we in fact invalidate it? I'm not sure one person can do it due to the amount of lawyer funds Slice is rumored to have available. Might have to consult an expert about this
@@christmas3dp unfortunately it’s a very costly process that can cost up to $50K USD, so it’s not likely to happen. A threat of boycott from the entire community is probably the more realistic and most effective action in this case.
@@sprkplg True!
@@sprkplg a gofundme could easily accomplish funding to do the legal work to invalidate the patent.
Slice lost me when they went on the rant about communism... I'll never buy their brand.
Great video!
Thanks for the feedback! Fortunately there's many more alternatives
8:38 I was going to write a wiki page on “Invest in Original Creators/Developers” or something along these lines, and this is a GREAT diagram that conveys how i think about this problem and how that is a solution! DAMN GOOD VIDEO
This is a sad story. Slice make good products using sound designs but their patent claim is ridiculous: four thin spacers is an obvious solution among many others and was used before. Not defendable but they can try to scare others. I understand their need of protecting their design from clones.. But the VZ hotend is far away from their design and is NOT a clone in any way. Their move is bad for the community and Slice eng. reputation. Just sad and stupid.
Now that I've actually had time to watch this video and read both sides arguments and evidence, I've come to this conclusion.
Communist utopia world.
All jokes aside, this is a lesson in bad PR. For your benefit this made an interesting video. To Slice's dismay, this will forever be a mark in their reputation. As for the others, those who are currently using Slice products will still realistically use them. Those who were never going to use Slice products won't use them still . Lastly, people on the fence can decide for themselves as we have the right to choose our equipment as we do not live in a
Communist utopia world.
Is there a link you can post for the documents you are showing to get a full context reading ? ;)
this seems like the type of video that'll start your channel off, the video quality is great
Thanks. It was a lot of effort! I appreciate it a lot
@@christmas3dp Yup, I edit for fun (sometimes) I get it takes a lot of effort to get something that looks high qualty
"Lemon" is sour because deep down they know how ridiculous and unoriginal is to patent such a basic idea of supporting something on bolt-on legs. Its like when another company with a fruit in their logo tried to patent product photos before white background. Or the shape of a rectangle with rounded corners. It must be a fruit thing...
Imagine if e3d patented their nozzle design. Slice E could been demanded for ip infringement.
They simply reveal themselves to be greedy.
An amazing PR strategy could be that they open all their patents like Tesla did.
Everyone should make a conceded effort to avoid slice engineering and run then into the ground. Let them have their stolen patent but no company behind it. There are many others that outperform offer work as well as their overpriced solutions. Bankruptcy for greedy, overbearing companies
Consumer-side activism almost never leads to bankruptcy. The sad reality is that they will continue to block innovation and gate keep what others accomplished before kind of like Thomas Edison. But supporting the little guy would help a lot in this situation and hopefully someone sues.
I wonder how hard it would be to get the slice patent deemed obsolete as it is literally just 4 posts between the heat block and heat sink.
Nice video. IMHO, as soon as legal gets involved, everybody loses.
This is a great video, and I agree that the patent is ridiculous and made for an unoriginal idea. Slice Engineering shouldn't have that patent because it is 1. unoriginal and 2. limiting for others to use similar ideas because it is something someone else came up with literally years prior. I hope their patent gets revoked so everyone can make use of this concept
This is why opensource should always if possible be patented, trade marked, copyrighted, documented ect and released on a license that any product it is incorporated into must also be open. Don't allow closed products to freely ride on the backs of open.
Oh boy... Imagine saying a Company can't have open source products and hold it's own.... What was E3D's last patent before Revo????
Hahaha specially in the 3D printing industry! Remember the Prusa Mk1 or 2? Literally normal bolts and screws 😂 or the 649183649174 iterations of the Ender 3 😐🤣 open source has not stopped Makerbot, nor Ultimaker, nor Creality, nor Prusa, nor E3D (and the list can go on for a long time)
*Imagine defending IP for a Hobbyist/Pro-Sumer FDM 3D Printing Product…when that market exists SOELY DUE TO THE INNOVATION POST FDM IP EXPIRING*
Spacers have been used in electronics and technology pretty much forever, their patent is akin to paintenting solder on circuit boards.
fantastic mate, keep it up! i look forward to future videos.
Wasnt aware of this whole saga but Im glad Ive never bought any slice products now.
Those are the most ARBITRARY patents ever. Im literally a welder and "bi-metal" products are not a new idea.
If someone wanted to "do their research", they could find some small issue like adding a completely useless third allow part to the design and patent it as "tri-metal".
"Scratch a liberal, and you'll find a fascist every time"
Creality uses two extra screws to mount there hotend to heatsink.( I see you covered this in the video MK8 )
I agree in general with Slice that patents can be important to protect IP and help companies recoup costs of developing new technologies. The problem comes from Slice patenting something that's so basic and frankly obvious. As you pointed out in the video people were using additional pillars to support the heater block years ago. So all Slice did was change a bolt to a tube and patent it.
Also, they can make patents. But the do not have to go after everyone for using. It's not like copyright where you protect it or lose it. They can patent this to protect from direct clones, and companies that do not innovate. But why don't they offer free licenses to original concepts like Goliath? Goliath is obviously not a clone of Mosquito.
This video was spot on. Calling out Slices BS. I am glad, when I was building my Voron I was looking at using Slice stuff with my LGX extruder, that was when I first learnt how crappy Slice is as a company. They would have had me as a loyal customer, trying to support an American company. Now I will not touch their products.
Set aside Slice Engineering's questionable patent and ask if what you are arguing is that no intellectual property protection should be allowed. This would ultimately crush innovation. The potential to make a profit and provide more opportunities for a person is a major factor in why innovation exists. The result of this profit motive is a continuous improvement in technology and ideas due to each party's self-interest in competing for a stake in the market. I am always wary of the "open source" model as it is not an honest approach and is exactly why 3d printing has in many ways stagnated with a ton of ender clone printers. None unique, none significantly better than the other, just market "white noise". I enjoy seeing someone make a fortune from a unique idea and see this as the best option for the largest amount of people.
Great Point! I believe in IP and Patents, however i think slice is different. Slice engineering patented something that's not just been done before and claimed it as theirs, they also responded terribly to criticism. Also, the ender 3 clones mostly beat it's origin to the ground! Look at the artillery genius or anycubic mega zero 3. Great printers at low costs that smash the Ender 3 with features, quality, etc. Creality sucks, and fortunately others could beat their products!
Innovation existed long before money or language; at the end of the day the law that restricts innovation directly will always be more damaging than the natural difficulty of innovation.
Patent law is inherently antithetical to free market principles, maybe the patent system needs more regulation and oversight to deal with issues like this. I have no doubt that any halfway competent judge would throw this patent out in a heartbeat, but slice knows that it won't go before a judge unless they actually take it to a lawsuit; obvious solution for them is to just shut down projects without going to court.
Another idea would be to require the patent holder to prove their patent is legitimate and being infringed before they send the legal threats, with the legal system or the losing party fronting those legal costs(streamline the process to make costs reasonable by eliminating lawyers and bureaucracy).
This would eliminate most patent trolling, of course there's still the possibility for a brain-dead judge to rule in favour of a brain-dead patent but it would have to pass a new judge everytime you wanted to shut someone down. It would also make the patent system more accessible to those without as much money, allowing the open-source community to operate on a less skewed playing field.
slice engineering patented something that was already done and claimed it as novel and unique. it was not. they did not innovate.
awesome video,quality is top notch
I appreciate it a lot!
The patent is invalid because of the prior art. We just need a fund to pay for lawyers to invalidate the claim.
its fun how all this only makes me not wanting to even consider getting anything from SLICE :)
A someone who is not from USA, I could care less about Slice Engineering. Also, donating to the veterans of the corrupt world police military certanly isn't something positive to talk about to the rest of the world. They got patent just because they are form USA, this kind of patent wouldn't stand at kindergarden playground, let alone in serious court.
what do you have against veterans? You can say whatever you want about the US government and military, what did some guy who signed up for free college and got his legs blasted off for the trouble ever do to you?
@@cpte3729 Whoever is willing to kill and plunder in a foreign country under the guise of "freedom", "democracy" and "defending" your own country on the land of another country (what normal people call invasion) just so he can have "free" education, doesn't deserve any respect. And yes, people make up government and military. Real veterans are those people that defend their country, not attacking others
That's why i cant buy myself a Schlong ??
No way i'll ever condider a slice of slice, even if i thought about it without knowing the full story
i heard somewhere that slice patent dont work in europe, i'm pretty sure that vez is from europe also in that case he did nothing wrong
As explained in 2:38, the Goliath was manufactured and sold by Mellow3D in China. On this same date the slice patent passed in china and so the Goliath was struck
vez is canadian. but the patent passing in china sounds weird, shouldn't they be able to to 'manufacture' but not 'sell' in china?
@@ItsDoneWithMirrors youp he was speaking french in one of his videos, manufacturing in china and selling where is no patent on standoffs sounds logical but i so much hassle and added cost. Last hope is kinematic coupling like in DropEffect XG or china being china and selling the goliath until slice will get mad again and the cycle repeats
Will never buy one of their products, I just don’t like how they act. 3D printing has born free to be capable of making at home things that aren’t available or that’s simple easier to do this way; and it has to remain a free market, where open source can and will improve the life of everyone of us. Sorry if I made some mistake but I’m Italian and I don’t speak in English very well
Wow. I just happened to buy an XG over a mosquito and now I’m really glad I did.
Im just now finding out about this. It's a shame too, I was going to use one of their hotends in my upcoming voron build and I was considering strapping one to my ender too. I'm glad I saw this before I pulled the trigger.
Excellent video.
Thank you very much!
good video 10/10 enjoyed it and came
Yep, this seals the fact that I will never be purchasing any products from slice again. Hope they enjoy all the business that they will be losing from the community.
@Jonas since you're heavily discussing slice's response, it is a good practice to link to the source.
In 2019 Toyota released nearly 24,000 of its patents for royalty-free use, including patents for its modern electric and hybrid vehicle technology. 24000! Do you hear this Slice Engineering?
I developed a hot end 5 years ago that separated it with a water cooler. You cant patent something someone else already designed.
It is shocking that standoffs got a patent
Does slice want to come after the trivets I put hot pans? Or motherboards?
Would be cool if we could create a decentralized entity (ahem...on the cardano network) that would be the "company" and it could act as a patent holder that would have an automatic, open source clause. Anyone could attempt to patent something, voted in catalyst, paid for through the blockchain treasury. This could provide patent protection by being patented. If that makes sense. Some companies do something like this, but this would be more transparent.
Don't know why, but slice's 'commie' statement reminds me a lot of McCarthyism for some reason
you ever wonder if McCarthy himself was the communist spy? He ruined so many peoples careers that he basically discredited any accusation of russian espionage for decades.
Some people in America calls anything they don't like communism, they don't even know what it means.
@@cpte3729 I think projecting needs to be a legal basis for investigation, the number of pedophile priests who give sermons about evil crimes being committed on children is way too high.

@@claws61821 wait so the statement lines up with McCarthyism?
i mean like you said the hot end for the e3 has 2 screws/ standoffs using the heater block to the body.... yea it's only 2 not 4 but we're arguing over semantics
Slice ridiculed by a random guy, posting a random video in his random small channel that I just stumbled upon. Ooh, not a bad start for the day.
Cheers mate and good morning! I am quite random to the public as a whole, yet in some communities you may have seen me before. Hope you liked he video :)
After reading the patent, I think if we don't use spacer made of stainless steel, zirconia or any combination of the two, we're not infringing the patent. Titanium will be okey like they do right now.

I need an edit now with the Boom Sound Effect and “The Rock” eyebrow overlaid on this subsection.
(Edit: Added Timecode for More Context)
I'll consider it
nice video jonas👍🏻
It's clearly a ridiculous patent that should have never been granted. How can you patent what has already been around for so long. I personally will choose not deal with a company that acts like Slice Engineering has.
I will never purchase from Slice engineering, that’s my contribution to this. But I will definitely by a VZbot with either Phaetus or Goliath Anyway, it’s mostly US law firm that try to enforce this.
This is the same kind of patenting issue and response that stiffles any progress in the industry. Much like the Stratasys PATENT US6722872B1 which they were able to keep in place for 20 years that prevented the rest of the industry from being able to implore the use of a heating chamber in their designs. Did this help anyone? Does Slice's decision help anyone?
I have been questioning Slice for awhile now even though I own and like their hotend along with the Dragon and Rapido. This is another strike IMO which isn't enough reason to completely write them off but combined with the absolutely insane levels of spam I get via text message after purchase is the final strike IMO. They probably think their issue is lack of advertising, it's not. They were shunned by Voron guys and as a result other extruders excelled. I have no doubt had they not been so petty the Mosquito would be much more popular today.
I will never buy, sell or promote anything to do with wankers like Slice Engineering, their clear Patent trolling will only hurt their bottom line as they will be losing sales more and more.
thanks for a video, now i know which brand i don't want to support! GO VZ!
This is great
Thanks, Saeko!

I'm on the fence about patents. On the one hand, it allows companies to maximize their ROI for engineering work by discouraging copies, which should encourage further engineering work to further improve design. On the other hand, lack of a patent allows for fresh ideas and new innovations that the engineering team internally may not have considered. Patents could also encourage outside-the-box thinking to find new solutions to avoid patent infringement. These new solution may not be ideal, or they may create better products that render the patented technology obsolete. I don't think I would patent anything personally, because if I really believe in an idea, then I'd like to see innovations on the idea from the community. I would take a Valve approach. If someone was doing some really cool work, instead of fighting them, I'd hire them. Slice Engineering doesn't have to follow my philosophy, though. They're totally within their right to protect any IP they have. My only issue is that the standoff technology isn't original, and I'd be furious if someone patented something I already created and introduced to the public. They've already cloned something, so I think calling out other clones of their product is hypocritical.
All in all, I say if we can't work with them, we can at least compete against them.
I'm more surprised that their stupid patent was allowed to go through. That's not innovative, utilizing a collar type spacer as part of a heat break assembly is not anything new. Goliath should modify their hotend to use a bar type spacer or non-tube design for a slim rigid spacer.
I'm building a couple new printers currently, I was considering Slice hot ends after hearing good things. But their response has completely turned me off to their products. They've been added to my "never buy" list.
just by itself the 2014 photo of the reprap movement, should serve to annul the patent of the pillars of the slice, because what they patented as being their invention, is a lie because it had already been invented by someone else. but I leave that to the lawyers.
the fact that they even got the patent in the first place is a mystery, and just goes to show how much of a joke the american patent office and courts are.
there's been hotends with screws as spacers long before slice engineering was even a thing.
When you can't innovate, make sure no one else can either.
I already avoided their overpriced products, thanks for pointing out their lack of morality. Now I wouldn't use their stuff even if it was free.
I don't know how well any of you understand American politics, but that communism diatribe is something I expect nothing less from people in Florida, where Slice is based in. And yes the same people will think that by "donating to veterans" their value is suddenly higher than the rest of you plebeians.
THANK YOU I FEEL INSULTED BY SLICE AND WILL NOT BUY ANY OF THEIR PRODUCTS
Slice going on an anti-communist rant: 100% confirming me not liking this company in the slightest. Capitalist trolls who'll never see any of my money.
If only Henry Ford had put a patent on 4 car tires.. just think of where we'd be today!
Yes I know.. But I doubt even google knows who made the first 4 wheeled wagon.
As far as I'm aware a patent can not be grant if it has already been shown in the public space before application, maybe I'm just stupid. if you patent someone else's idea that is immoral bad slice engineering. because the support design has already been shown surely makes slice engineering patent invalid.
In the US you have 1 year from the first public disclosure until you have to file for a provisional and then one additional year from when the provisional is filed to put in for the full patent.
@mmiscool thank you good to know 👍. I have a couple of patents to work on next year but these are not trivial ideas 😉
@mmiscool reprap had this design with stand offs for the hotend over 11 years and released it as opensource.
@@Big3dprinter If there is prior art you can request the patent be re-examined by the patent office. Chances are you can work around the claims. If some one wants to break down the claims that is fine but I think the patent they have is slightly more involved than just having 4 pillars. The company also is not acting like a patent troll as they are actively working to sell the product and not just suing others in a shakedown for licence fees as a non practicing entity.
Dear Slice,
If you want to beat another company, BE BETTER THAN THEM!
I own MULTPILE - AND *EXPENSIVE* Slice hotends.
I HIGHLY doubt Vez will bankrupt you guys. I would stand down and let this go, if I were you.
BTW, can't "prior art" get a patent revoked?
Great arguments here, Jonas!
BTW, New sub.
3D printing is an open source world. Patenting a spacer is fine if you use it to stop clones but this is ridiculous!
Slice is putting themselves in a corner. I couldn’t afford their stuff if I wanted and I definitely don’t want to now.
Oh what a generous donation from Slice, you are the stewards of 3d printing! Sanjay would be rolling in is grave.
Thats what i thought!
Well I've been OOTL, but at least now I know not to give Slice a dime. Consider the following passage from an all3dp article I was just reading about enclosures:
"Stratasys was one of the first pioneers in 3D printing back into the 80s, but due to their overwhelming number of patents, commercially-available 3D printers remained out of reach of the general consumer until several key patents lapsed in the early 2000s. Many of these patents remain in place, including some that feature enclosures. However, several important patents are set to expire in the mid-2020s, which we’re hoping will allow for some amazing innovation."
Leave it up to a bunch of Florida boomers to make a quip about "communism" for a patent that they evidently should have never even gotten in the first place (prior art) when THEY WOULDN'T EVEN HAVE A MARKET TO SELL THEIR PRODUCTS TO if all the original patents surrounding 3D printing hadn't literally timed out. It is never about "innovation" when it comes down to this stuff in America, it is about monopoly, resting on your laurels, and doing something once and continuing to profit off of it forever.
Love the intro
Thanks!
Patent trolls?
1. Stratasys was the first or one of to make hot ends like this 4 screws 1-2 standoffs was the same on several models long before sliced bread!
2."Love" sometimes you have to protect your loved ones! even if you wear a unicorn on your sleeve
3. Great Video thanks for your angles i think this was needed
4. screws and bolts may never hurt me but names last forever
5. maybe we should patent an automotive radiator while we can? does mount with 2-4 bolts and standoffs too
6. engineers know better than to try and patent pre existing century old nuts and bolts or washers and spacers they are not your design you never made them and I feel nothing unique was patent but only others inventions either stratasys or Tomas edision or duke domville
7. the part about you know... clearly shows not only the level of engineering but the level of politics moving into printing???? wow is there further direction to this to come i wonder...? maybe an APP...
8. overview -the whole damn thing is thermal dynamics nothing is actually MADE by the maker to be a Patent in my opinion yet the arrangement that already exists! via Fasteners from the hardware store and nothing more.
I feel they know its not going to be challenged as the start up guys simply cant contend with them even if it was for making a cheese sandwich! like municipalities they too will dry you up long before you get to make your point and for this reason we have loving things like open source support!
unicorn in training
care bear count down!
Vezey dont ever stop YOU! but I understand when the 7 is stolen from the calculator you must recalculate (cant wait to see the changes!)
Cheers
new sub here
Slice’s creativity and innovation is stagnant had no other choice other than to patent.
Then what gives Copycat Chinese companies the right to register names such as: LDO, Voron and others that have spent time developing their products? Babu Labs seems to be hot in the market now. No open source there either but, everyone is buying one......
It's a little bit funny the inyection molding example, how much that machines cost. The y are almost a very few of them in 3dprinting, that's why we can have cheap machine in our houses. So they use an open source community to sell expensive close source hotend, nobody should buy the products.
The buddas extruder, great example, that hotend also have a kind of bi material heatbreak
