I had the opportunity to catch up with Dan from Slice engineering to talk about their incredible high flow rate Mosquito Magnum Plus hotend, plastic repellant paint that keeps your nozzle clean, and finally a silicone sock for their mosquito hot end.

Oh, a Slice engineering video....time to grab some popcorn and read the comments!
I like how it's featuring a slice hotend (whatevs) but the description has a link to e3d revo. LOL!
That is ironic, buy it's likely due to E3d sponsoring his trip to CTC.
This product is for users trying to print as fast as possible with a bigger nozzle. Think Core XY at 200 mm/s through a 0.8mm² nozzle, which requires around 90mm³ of melted plastic per second. This hotend allows you to melt over 3x as much plastic as a standard volcano (30W). If your printer is making you money, then this hotend allows you to print 3x as many parts (3x money) per printer, so $400 is easily justifiable in that case. If you're printing small doodads on your $200 bed slinger then obviously this isn't the hot end for you.
It’s a well built product for sure, but 400 does not make sense to me. While e3d is trying to innovate and bring the cost down they are adding slightly changes in the product and charging a lot for it. They are positioning themselves as a boutique brand with boutique prices. I wonder how long they will survive when the new e3d quickchange gets mass adoption.
This is exactly my first reaction to this. After watching the E3D product release, I wonder what Slice is doing here?!
Only thing that makes sense is targeting industrial/education markets. Hobbyists and print farmers are going to have a hard time justifying ultimaker and zortrax pricing, but if they can figure out a way to market themselves to markets with excess money wanting a "professional, highly polished", product they may have a chance. I can't for see any circumstances that would result in me dropping a printer on a hotend...
@@super_slo this is not professional nor highly polished, it looks goofier than the supervolcano
400$ is to much. Also when u look at the hotend, only thing you see is patents,patents,patents!!! That says a lot about that company, especially when they are trying to sell it to open source community... a big dislike from me
Yeah. Unfortunately this is incentivized at every level. As a ME, it helps ur career if your name is tied to developing more patents, and companies obviously make money off of them various ways.
Can’t tell you how many supervisors in the engineering world have an insane number of patents. Mostly bc they “supervise” the lower engineer that actually developed whatevever te patent is and then, somehow, bc they glanced at it and maybe offered 1 or 2 critiques, they get their name tied to it as well.
Slice also specializes on patent crapola
...and generalised ¢untery.
Nice interview, thoughtful questions and answers.
Adam, what is your opinion on the application of thermal paste to heat breaks?
Why would you use PTFE when you can paint on WS2 and the plastic won't stick. It also won't burn. You can use high speed impingement to apply it. There is an ASTM standard for it.
I thought Teflon couldn't go above 260°C due to it breaking down an releasing very toxic fumes. how are they getting it up to 290 and saying it just not effective, and you'd need to re-apply it. They make it sound like it's no big deal, but that a major health concern.
They likely have copolymerised it with something else to improve the decomposition temperature to 290 or a bit higher, the melting point is 300 so the limit is probably there due to that rather than decomposition. Copolymers tend not to be used on tubing or in the hotend as they want to maximise hardness and minimise friction. this is less important on the end of the nozzle.
@@bluedeath996 I expect it is actually the exact opposite.
Generally, impurities lower decomposition temperatures.
So more likely the paint is pure material, and the tubes are copolymerized with something to make it more durable.
The plastic repellent paint is only 1% PTFE by volume, and the amount of material that gets applied onto the nozzle/heater block is incredibly small.
@@creeper360bill yeah 99% water. But when that 99% water dries all that's left is the PTFE (+ any other additives they put in there)
@@brandoneich2412 This. Super this. IMO this is frankly a lot worse than running a bowden-lined hotend at 290. Because with that, at least the decomposition is happening inside a pretty well sealed chamber, with very little of it making contact with the hot zone. With this stuff though - here all of it is directly on the outside of the heaterblock and nozzle, cooking off in atmosphere while being continously blasted with back wash airflow from your coldend and parts cooling fans. Extremely efficiently dispersing it into the surrounding area/room.
Until SE produces some verifiable, independent lab safety tests on PTFE decomposition @ 290°C for _at least_ a couple of hundred hours of continuous printing - this goes firmly at the top of my "Sketchy asfuq severe health risk" product list.
I like how desperately he/they try to avoid saying E3D when the talk about their nozzles.
...ahh yes "smaller nozzle" "12mm", "RepRap compatible", that's how everyone describes them.
Same listening to this conman speak makes me furious lmao.
@@davechuasoup lol what
@mr gunk they claim and legally try to enforce that they invented hotends completely independent of outside inspiration, ie they never even saw an e3d product ever. Miraculously though, their nozzle and the e3d nozzles are completely identical in dimension.
Is that robot design available anywhere? (the one shown in the b-roll)
I like this Adam, the flexing was also such a special part :)
I was wondering could I get a mosquito then later upgrade the block to this?
I assumed that the threads were a significant insulator. My workaround to this is to use anti-seize. Eventually the Grease burns off which still leaves some air but it at least adds some solids which should increase the contact area between the threads and promote heat conduction across the joint
.
Unfortunately I didn't collect any data for this when I was flow testing my hotend modifications and it's a pain to clean out so I probably won't retest this condition. It's easy and cheap enough that I would just do it for any nozzle swap.
Copper or aluminium based? Did you have any issues with it seeping out/down the threads and nozzle? I've been thinking on trying this, but have worried a little that it would seep down along the nozzle and eventually end up on the print.
When the hotend costs as much as 2.5 ender 3s!
4 ender 3s with the magic microcenter coupon
Thanks for the loud beep at the beginning
I dunno about anyone else, but I wouldn't want to have a big "patents" link on my hotted. Bit tacky.
PTFE fumes coming from the nozzle... nice - no thanks.
"Good to 290" Yeah, someone has never read a SDS for PTFE. John Olive just had a nice bit about PFOA's. I immediately thought about this product when I saw it.
@@JamesBrassill if you don't mind to get cancer its fine so
@@philipp2104 PTFE fumes won't give you cancer, they will give you teflon flu and kill your pets. They might kill you too, but hey at least no cancer, right?
with all the buzz about ptfe-lined hotends and their potential health effects at high temps, literally slathering ptfe right on the nozzle set off an alarm in my head lol. The bottle probably has a warning about the how toxic it is in the state of California.
Pass.
Dam the sock is sold out waaaaaaaaaa
What i that droid in the video
Wow. Suspending a PFAS in water and heating it sounds like a HORRIBLE idea. Teflon in it's solid state is already a terrifying material as is.
So, does this hotend come with a free complementary lawsuit when you buy it? I hear Slice is big on that.
Nope, that's only free to people ignore their _granted_ Patent and selling/reselling a product infringing on that Patent.
@@Duraltia Oh sorry, it's hard to tell when the legal ground starts and ends when companies start racketeering vendors in the US for selling the Dragon, and even harder when they try to force their way through intimidating completely unrelated projects, like the hotends by australian company Takoto with their lawyers, until they realize they have no legal ground to stand on.
It's also hard to tell what's an abusive patent when words and expressions start to get patented. Heaven forbid anyone could ever be able to make a hotend with a nozzle that can be changed with one hand (also good thing I was able to reword that before Sleazy engineering could sue me)
@@Duraltia Fuck that patent that had prior art and fuck slice.
@@JamesBrassill Ah but you see, the prior art was eeeeeeeever so slightly different so it's totally ok. But what's not okay is to modify the design even by a landslide now that corrupt american patent judges greenlit it. It's all "legal".
@@Duraltia Their patent is bs. Creality had a multi support hotend before them.
Others have too.
Just because they got it legally granted doesnt mean they arent the bad guys here.
Is it just me or does he seem a bit nervous when he mentions that your viewers should know the Mosquito, like its infamous for some reason.
He's referring to this: th-cam.com/video/bDx0hCBUI28/w-d-xo.html
I need santa to bring me a magnum plus.. Will the bondtech CHT nozzle fit (they claim 30% extra flow from their core heating)?
Yay for silicone sock "welly boot" XD
Yep it fits
hmm, PFAS in liquid form
LSD extruder beats you
I love slice, but 400 is a brand new printer.
this isnt for those printers. they can be, but I wouldnt.
you could buy 3 of these for just the cost of the servos on my printer.
@@qwertyuiop6046 have you priced copper recently? thats a large chunk of copper in there.
Tribalism is real in these comments
I love your channel man, but I have to dislike this video out of principle cause it's giving my most hated company publicity. Sorry man.
Not a fan of proprietary parts froml slice and e3d. Goes against the open source nature of the community. Compete on quality, don't limit innovation.
LoL $400.00 for a hotend? Umm no.
talk about overpriced.
I'm a huge E3D fan, but Slice makes me want to get another Ender just for Slice equipment.
Buying a hotend that costs more than the rest of the printer seems like an odd choice...
@@_Piers_ Over paying for a 3D printer sounds like a poor choice. Trust me I hate the fact I bought a Ultimaker 2+ when the Ender 3 out preforms it.
