Ah vortex tubes, I haven't thought about making those for 15 years. I tried with plumbing parts and never got one working. Now I'd really like a 3D printer.
Thousands of 3d printing videos out there and of course yours is such a cut above the rest.

Hilsch Vortex.... It separates high and low energy gas molecules, but I'm pretty sure it can modify the oxygen/nitrogen ratio of air much like a gas centrifuge. Pity it takes a lot of energy to run, as it conceivably could be used to deplete nitrogen before going into an internal combustion engine in real time. I've wondered about this for 3 decades - If you have the tools to analyze the composition of the output, I would really like to know whether the effect would be useful.
Andy Lee Robinson What about for performance applications in IC engines? Although I've read that nitrogen is important to "cushion" the combustion event, hence the use of N2O/nitrous oxide injection instead of just oxygen injection. I've also read that nitrous oxide starts to "break up" ignition events at high power levels and it is why forced induction via turbo/supercharger or ultimately just plain compressed air is better. But maybe compressed air depleted of nitrogen a bit?
I don't know about knocking and cushioning, but I would think that an engine running on pure oxygen and gasoline would have terrific performance and produce no dangerous nitrogen oxides, and no CO if the combustion is complete. Perhaps there would even be enough energy left over for carbon capture. Hypothesis probably moot now as IC engines will be phased out of the mass market over the next couple of decades.
Not an engine expert, but I was under the impression that running an engine too "lean" (more oxygen to fuel) already burns hot enough to cause engine damage. Wouldn't this cause the same problem? One might need to redesign parts with higher operating temps in mind.
I was reading about the Formlabs ceramic resin. There is a big drawback-- it shrinks when you fire it in the kiln, burning off the carrier resin and leaving the ceramic. The shrinkage is dependent on the angle you print, too. This means you have to guess what sort of unequal scale factors to apply to the model so it will shrink to your desired size. All the other resins are quite dimensionally safe, allowing for those threaded parts and marquetry fits.
Shapeways offered glazed ceramics at least in 2011, but they discontinued it. Hella expensive. People designed lots of espresso cups: they're somewhat small, and the kind of people who drink espresso probably are more likely to afford them...
I am jealous of that 3D printer but what really shocked me was how much resin you must be going through, and that stuff is not cheap! Welcome to the 3D printing game though. Looking forward to what you will be doing.
USWaterRockets I’m a resin mfg for 3D printing. And I agree, it’s too expensive. What would you consider fair on a ml or liter basis for standard prototyping resin?
Avenue X, can I hijack you then, i'm less worried about the price, even if it is quite limiting, but about health impact. Dr. David Light from a Houston hospital said he was aware of some people being hospitalised with severe respiratory issues and one with persistent near-complete memory loss, who had a DLP printer at home. I understand that such impact may be very rare, but the risk is too severe to ignore. The resin was not specified, but I have my suspicions as to what it might have been. Do you think something can be done to make resins genuinely safe for home use? Especially if you could just about match the pricing of some of those cheaper suspicious resins, you might have a winner of a product on your hands.

I LOVE your videos man! If I had to limit myself to 10 content creators on youtube, you would definately be in there eventhough you dont post as often as others, your content is worth the wait!
and there is the Baader-Meinhof phenomenon in action- 2 weeks ago I hadn't heard of tesla valves- now it casually comes up in about every video I watch
That's pretty amazing. I've been looking for some plastic moulding clips for my car that are no longer made. Now I have a reason to buy one of these. Hehe.
I was thinking about that. At first it seemed like they wouldn't like people printing parts, but if I need a 314 stainless steel part, I could print it first to make sure it fits and is exactly what I need before ordering, especially in large quantities. Its great for making sure you're buying the correct part. A plastic print is worth about 50 cents, and is no substitute for $30 quality metal parts. This should be a win-win, at least in most cases.
MMC might agree with you, but I doubt they make all their models themselves. They're probably just passing on the license they're under from their 3D model suppliers.
The models are designed to test fit their catalogue to your designs digitally as part of product evaluation for purchase, and this is emphasized in the terms of use. It stands to reason that they don't want to give away their models to let people produce their own end-use parts, they are supposed to be a helpful tool for engineers and to help them sell their items. But it is to be considered that not everyone needs parts of the same strength and quality, a flimsy plastic dimensionally inaccurate part can be as good for some uses as a precisely machined metal one - but there's no reason why McMaster or their suppliers would want to or have to give away their property to enable those use cases, to their own detriment. Also to be considered, rapid prototyping techniques are developing at a rapid pace. SLS (laser sintering) is an existing technology that can be applied to metals. It is conceivable that we might have an affordable (
I'm assuming that they will publicly say to not do it, but won't care at all for personal use only. They know that your 3d printed part is inferior to their product.
This is great, the Form will be a great addition to your equipment It's a great video really showcasing all the features of the Form (and SLA in general) and it's actually the first time I've seen the color kit in action Can't wait to see what you'll do with the ceramic material
I suspect the vortex tube might not be performing as expected because you scaled it down by half - especially if it was specifically designed for air because of the intramolecular forces involved in compressibility of a gas at different scales. The efficacy of the vortex tube surely depends on the taper ratios being tuned to specific scales and so a direct scaling of the entire tube won't produce something that works as efficiently or effectively as the original design. I could be way off, but that's my theory. It does appear to be working at least somewhat, so that's cool. It's a heat pump!
That internal tubing and printing in negative space gives me an idea for a challenging project. You should try and print a Bernard Gitton style water clock, completely encased in resin! These clocks are usually crazy expensive and difficult to build because of all the specialised glass components, but printing the pipework in negative space could result in a very beautiful, miniature water clock!
i've been waiting for your debut into 3d printing, and my lord what a start. this is incredible. i have the form2 at my makerspace, but i had no idea how clear it could get
I've found that the McMaster-Carr models can have some variability on shoulder bolts, dowel pins, and threaded fasteners. Always worth a double check with the print before you go to order.
I'm a facilities manager for a cast acrylic factory, we make tubes and solid rods, we supply McMaster carr all of their cast acrylic tubes from 1 1/2" to 8" with wall thickness at 1/8" , 3/16" ,1/4", and 3/8". And solid cast rods from 3/8" all the way up to 6". If you've ordered cast acrylic from them, its come from us. McMaster also sells extruded acrylic, but it's cheaper and less machining friendly. And it doesn't come from us haha. U.S. Cast. - American made, owned, operated, and supplied :)
Doug Ankrum Ah, that isn't fun man... Hope it's nothing serious. I'm a radtech, so I've had several myself, but only one for a medical reason (the rest was for testing new sequences). People tend to overestimate the resolution of an MRI, so I thought that might be the case here too. Never even thought of making a 3D reconstruction of a brain, and converting it to a printable file. I have 0 knowledge about 3D printing, but I'm thinking about trying this myself. Would be cool to have my brain on a shelf...
You may be late to the 3D printing game but you have one of the coolest toys out there. My 4-year-old 3D printer that I built myself cannot do that. Too bad the Form2 is too expensive for me to afford or else I'd be all over it. I guess the next qualitative jump will be to 3D print brains with actual neurons. We're not quite there yet, but there are some advances in the area. Simpler organs like liver are already being worked on.
Very curious about the possibility of printing the YBCO superconductor devices. Looking forward to a video testing the efficacy of that process. Do be careful, that does actually sound like some pretty revolutionary IP, and I'd hate to have this video prevent you from taking out any patents. Novel geometries of superconductors: very interesting concept. It seems like the issue here might be controlling the alignment of the crystalline structure. Perhaps inserting a seed with a known alignment is in order (not sure if that would work with YBCO). Sounds like there are some applications in MRI-land. Perhaps this could improve the performance and/or manufacturing process for SQUIDs, too. Sky's the limit here - please do follow up with either another video, or, better yet, a startup with a few provisional patents in hand. Also excellent job with the microfluidics devices. Excited to hear that Verily is actively thinking about applications of that tech, hopefully you guys can pick up where Elizabeth Holmes left off ;)
I almost didn't click this video because I've already seen a lot of 3D printers but when I realized it said high res I decided to check it out and I'm not disappointed. The new Form 3's are actually quite affordable for their specs. Not sure about resin prices since I don't actually have a 3D printer of my own and don't know how much resin I'd need but it looks like that would be where I'd struggle (a high one time cost for the machine is less of an issue than a high cost per part).
Ben, you are really amazing. I am always waiting to see your new videos. I believe 3D printing technology (metal, biological material, buildings, ...) will have made our future. In the field of plastic mass production, they made a 3D Printed mold that is used for plastic injection. the main problem of making product especially resin base ones is the price of resins. I haven't seen any open source formulation related to make a resin. I suggest making an open-source resin for this community
i cant wait for 3D printers to become so cheap they are in every house, i think it will be as big of a revolution as the time when everyone was getting PC in their house and internet was becoming a thing
I don't think that everyone will need it for a while, it will be a massive revolution but not something that everyone needs. I am sort of thinking of the services that print things overnight and send them to your house. That is what the majority of people will need because most people don't need to print often enough to warrant a dedicated device in their house. Just my two cents, and entirely up to speculation!
Formlab could not have had a better advertisement than this. Besides, if they're sponsoring you, it might be worth mentioning that. Same if they arent.
Alexander Sannikov Nah, I am sick of people feeling like they have to say things like, "Formlabs has not sponsors me. I bought this with my own money." People don't believe them when they say that anyways. I like that he didn't say that.
re: Vortex Tube The thermal conductivity of the plastic is probably a lot less than that of metal. That means that the hot end won't won't get rid of heat as effectively. It would be less elegant, but you could probably design the vortex tube in pieces, and have the hot air pass through a copper or aluminum tube. If it has fins, so much the better.
It looks like a lot of teething issues have been fixed with the Form2. I would caution anyone against buying a used Form 1+ as a cheaper alternative. It's still a gorgeously made 3D printer, but I think it was very much a beta product. Some people had no issues at all, others could never get it to print reliably (myself included). My own opinions here: When the 1+ was released, there was no good documentation on post-print care. The instructions we got with the printer were laughably simple. We figured out that we needed to post-cure with UV, but it's only recently that Form developed proper wash and cure stations. These are absolutely necessary for good prints, and manually dunking in a bucket of IPA doesn't cut it. The printers are pretty sensitive to optical issues - dust on the galvos, smudges on the base of the tanks, the inevitable fogging (UV damage by the laser is inevitable, so the tanks are disposable after 2L of printing). Over time the software got better at support design and patches included easy-release tabs on the prints. Old resin will crack tanks - found that out the hard way when it leaked resin into the printing cavity, fortunately missing the important bits. In short there were a laundry list of little problems which meant that we could never get it working well - I don't think we were ever able to replicate the helix rook that Form provided as a demo print. I really wanted to love our SLA printer, and on a good day it's easily better than FDM or SLS, but it was so much faff making it work reliably that it's left a sour taste. This seems to be echoed by a number of other 1+ users on the support forum when I was trying to find comparisons. Happy to be proven wrong here, because the results in this video are very enviable.
One of the very first 3-D printers was a laser/liquid....but it was 'inverted' the laser cured the top layer (maybe .002" or so)...the part moved down as it was built.... I saw one at a tool show in 1995.
This is a really amazing video! I just purchased a form 2 and I'm really interested in doing time delay photography like you're doing here. I'm currently filming for my channel on my phone, so the high end camera might end up being a bit of a barrier for me...
A friend of mine in the 90s had a machine at work that he called "stereo lithography"... this souns like an affordable-budget version of what he described.
Read about 3D printing in Wired back in the late 90s. THIS is what was presented (along with a million dollar pricetag) back then, and I've been disappointed with commercial 3D printer offerings ever since. Finally the 3D printer of my dreams looks affordable!
7:24 This is perfect if I really want to know measurements and details. I know exactly where to drill when start experimenting and learning how to lobotomize on myself.
I actually have a brainscan lying around from a study I was a part of many years ago (I got painfully electroshocked in an MRI at random intervals) I also happen to have access to a resin printer of the industrial variety right now. Excellent timing, I just need to get an external CD drive to read the damn thing.
From the looks of it, you could modify such a printer to have a small air port on the moving print bed, so it could stop and blow out the epoxy not set so it doesn't get set later by excess light. This could potentially let you print finer resolution micro-fluidics.
That is pretty awesome! I wonder exactly how strong the various materials they offer actually measure. I also wonder if the frosted finished products could be made clear with an acetone vapor bath, like the way regular 3D printed stuff can be smoothed out with acetone vapor. If so, that would allow for making clear parts that aren't flat for sanding.
I am convinced you can cast+machine just cavities. You just have to make a water-solvable placeholder for that cavity, then pour epoxy into it, cure it, let the water-solvable plastic dissolve and you'd have the same result. Obviously this can be done with other materials than I mentioned, it was an example to show of my point.
That's an incredibly slick method. But it appears in the videos that the laser beam(s) fuse the resin at certain locations in the bath. But how do you stop a light beam at a desired distance? I assume the beam(s) are focused at the desired points to (a) fuse the resin at that point and to (b) avoid fusing resin along the path of the beam(s). I'd be interested in more info about how Form Labs' method works.
The future is bright on this channel, very cool ideas :-) I'm not sure if you should paint-coat the parts that are going to be used outside to protect them from the sun (UV)?
As awesome as SLA is, I would still recommend getting a high quality FDM printer for your own shop. Sure, the accuracy isn't the best, but the speed is hard to beat, and you don't always need to print microfluidic structures.
Hi, Really interesting video I've actually done similar things to your micro fluid experiments on a similar dlp printer (kudo titan 2) for a healthcare company that needed to do scans on heart vessels repeatedly to figure out good settings. I was able to get the smallest part of the vessel down to 100-200 microns. Have a nice day and keep doing interesting stuff ~Kira
Hii, amazing job. Could you please tell me how do you clean your prints? I want to make some microfluidic devices, and whenever I made channels with diameter smaller than 1 mm, I get the resin stuck inside and the channels are blocked!!
Michael Scofield That's good thinkin', but besides the problem of the snorkel blocking the laser, the snorkel tube would also have to be extremely thin because of the way the machine works... The print is made up of layers, and the way the machine creates these layers is it holds the already-printed portion of the part a fraction of a millimeter above the bottom of the resin tank. The laser then cures that very thin layer between the floor of the tank and the existing part. When the laser is done with the layer, the machine lifts the part, wipes the floor of the tank, and then lowers the part back into the tank (leaving a new gap, which will be where the next layer will be formed). The snorkel would have squeeze through that very thin gap.
I'm not much into the 3d printing scene but I do remember a Ted talk about Carbon3d. It can print very fast. Although I don't know of its precision. Just curious if you heard of it before.
Tesla valve is like a diode for liquids, or gases. I would think that if you vibrate axially it at the right frequency, it would behave like a pump and never wear out. May even be useful for an artificial heart.
Good luck with the temperature resistance resin. I have been using it for my prototype. Been auto-calved my parts at 120C for 15 mins and used at room temperature. The trouble is, the part became white, mat, very brittle to the point it break too easily ain't even usable. Have so much problem with it for the pass 6 month back and forth with formlab and they just wont acknowledge the problem. To me, the idea of all the different type of functional resin is amazing, but the technology just ain't quite ready yet. They have also just changed the user guide for resin tanks after years of cracked tank complains. So now you can't have resin stayed inside the resin tank for over a month. I have no idea what to do with mine as I do regular small prints every 1-3 days on each resin tanks. It is a nightmare if I need to clear them out every time. Plus you can told not to pour your resin back into the cartridge, so storing them separately is a pain.
A Promo Code and a Bunch of Savings is alll I need! 🙏👀👌 Each of those parts are definitely as detailed as I would like for 3D Modeled Objects. They're so functional! I don't think the striations caused by an extruding printer could match the structural strength of that lazer Printer either. Just, Wow!, that's so Cool!
Did you ever do a follow-up on trying out making the ceramic form-labs stuff conductive? (I think that's what you were talking about experimenting with at the end of the video?)
would there be any purpose in a 3d printed superconductor? couldn't you just cover the surface of a 3d printed plastic form with superconductor and it would work the same?
I can imagine uses for 3d printed superconductors embedded in a suitable 3d printed insulator. There's sensors, switches, and BIG MAGNETS! Muhahahaha. ...and that's just the start.
I'm so intrigued by the Forms printer. But, if overhangs require support structure (as mainstream 3d printers do) then how are you printing those embedded passageways inside things? how can there be a 90 degree angle hollow tube inside a cube without needing to break away support structure inside those tiny capillaries... or did you have to do that ?
Yeah, I'm pretty late to the 3D printing game too (as in I haven't bought one yet, but do get some things printed at Shapeways). Being able to print ceramic is mind blowing to me. So I'm up in the air as to do I get Formlabs or some PLA/ABS depositing printer. I would like to print Kynar (Fluorinar) which I've only seen Ultimaker print.
I stunned how good form 2 seems to be in through hole and "inside holes" stuff. I have sparkmaker - its of course no way comparison to form 2 but its also sla - and this stuff gives me most of headaches. Holes smaller than ~ 1.5mm comes out filled with half - cured resin, like a puddy, and you need to push it through (with a small drill bit for example), and hope it got not too hard. I wonder if new anycubic photon 2 has the same problem since paying 2k for form 2 is not an option unfortunately. I was wondering maybe you using ultrasonic cleaner maybe?
I remember being laughed at by my peers when I showed them a 3D printed gear - it was printed via powder process back in the late 1980s! So a big deal back then, they told me it was impossible to print in 3D never mind such a complex part - oh how technology has moved on"
Hello, I have a query regarding the formlab capabilities; can it be used to print 3 way valves like "3 way stopcock medical valves", the tunnel and the rotary element has to be aligned perfectly to avoid leakage

3D printed ceramic? The future was here yesterday I guess. Now we're in to science fiction-turned-science reality
Metal, ceramic, plastics, wood, fibers, so long you can deposit the item, you can print it.
I was reading about the Formlabs ceramic resin. There is a big drawback-- it shrinks when you fire it in the kiln, burning off the carrier resin and leaving the ceramic. The shrinkage is dependent on the angle you print, too. This means you have to guess what sort of unequal scale factors to apply to the model so it will shrink to your desired size. All the other resins are quite dimensionally safe, allowing for those threaded parts and marquetry fits.
It should be possible to simulate the shrinkage with the right software, right? So you would be able to adjust your part accordingly before printing.
I guess you still have to fire it - so we are still a long way off from a Star Trek replicator than creates a hot cup of Earl grey!
Shapeways offered glazed ceramics at least in 2011, but they discontinued it. Hella expensive. People designed lots of espresso cups: they're somewhat small, and the kind of people who drink espresso probably are more likely to afford them...

Drakkar Calethiel yep even metal.
SLM and DMLS are nothing new for me but printing ceramics was totally unknown for me.
That's pretty amazing. I've been looking for some plastic moulding clips for my car that are no longer made. Now I have a reason to buy one of these. Hehe.
If you read the terms of service for McMaster Carr, they forbid 3D printing of any of their models. Figured I'd give you a heads up.
hey software pirates have long dreamed of pirating hardware, this part of the video made me want to get an SLA 3d printer even more.

But it is to be considered that not everyone needs parts of the same strength and quality, a flimsy plastic dimensionally inaccurate part can be as good for some uses as a precisely machined metal one - but there's no reason why McMaster or their suppliers would want to or have to give away their property to enable those use cases, to their own detriment.
Also to be considered, rapid prototyping techniques are developing at a rapid pace. SLS (laser sintering) is an existing technology that can be applied to metals. It is conceivable that we might have an affordable (
I'm assuming that they will publicly say to not do it, but won't care at all for personal use only. They know that your 3d printed part is inferior to their product.
i love these videos so much. theyre like.. so calm and thoughtful, well paced..
in youtube terms this is life saving content
While being late in the game, you made one of the most in depth and B$ free rundown on SLA. I can't wait for your experiments with ceramics !
This is great, the Form will be a great addition to your equipment
It's a great video really showcasing all the features of the Form (and SLA in general) and it's actually the first time I've seen the color kit in action
Can't wait to see what you'll do with the ceramic material
I suspect the vortex tube might not be performing as expected because you scaled it down by half - especially if it was specifically designed for air because of the intramolecular forces involved in compressibility of a gas at different scales. The efficacy of the vortex tube surely depends on the taper ratios being tuned to specific scales and so a direct scaling of the entire tube won't produce something that works as efficiently or effectively as the original design. I could be way off, but that's my theory. It does appear to be working at least somewhat, so that's cool. It's a heat pump!
Formlabs also sells a rubbery-like material for printing with the same 3d printer.
That internal tubing and printing in negative space gives me an idea for a challenging project.
You should try and print a Bernard Gitton style water clock, completely encased in resin! These clocks are usually crazy expensive and difficult to build because of all the specialised glass components, but printing the pipework in negative space could result in a very beautiful, miniature water clock!
i've been waiting for your debut into 3d printing, and my lord what a start. this is incredible. i have the form2 at my makerspace, but i had no idea how clear it could get
kind of late at this 3d printing game > fills the gap with a killer machine. good job
Every video Ben reminds me of what Christmas Day used to be like for me as a kid.
I've found that the McMaster-Carr models can have some variability on shoulder bolts, dowel pins, and threaded fasteners. Always worth a double check with the print before you go to order.
How does the model of the windmills you printed look when placing a normal LED under it, does it carry and diffuse light like acrylic?
I 100% need a copy of the windmills. That's so nice looking!
So awesome! Big things will come from these emerging technologies. I would bet my life on it.
I very much look forward to the 3D printed superconductor, good luck!
I would love to see what you can achieve with the 3d printed superconducting composite material idea!
I'm a facilities manager for a cast acrylic factory, we make tubes and solid rods, we supply McMaster carr all of their cast acrylic tubes from 1 1/2" to 8" with wall thickness at 1/8" , 3/16" ,1/4", and 3/8". And solid cast rods from 3/8" all the way up to 6". If you've ordered cast acrylic from them, its come from us. McMaster also sells extruded acrylic, but it's cheaper and less machining friendly. And it doesn't come from us haha.
U.S. Cast. - American made, owned, operated, and supplied :)
You need a bigger printer for your brain.
I was going to say something...that brain is quite small....
Doug Ankrum The resolution of a regular brain MRI is too low to be scaled up full size...
Yeah, I got that...I've had 3 MRI's so know the deal...!
Doug Ankrum Ah, that isn't fun man... Hope it's nothing serious.
I'm a radtech, so I've had several myself, but only one for a medical reason (the rest was for testing new sequences).
People tend to overestimate the resolution of an MRI, so I thought that might be the case here too.
Never even thought of making a 3D reconstruction of a brain, and converting it to a printable file. I have 0 knowledge about 3D printing, but I'm thinking about trying this myself. Would be cool to have my brain on a shelf...
laurens b That way you can do a lot of drugs and still have a backup brain!
I generally don't like 3D Printers, but this is one I can get behind! Great stuff!
Seriously, just found/followed this channel. Amazing man. You rock!
I saw a video about this stacking printer, and have been waiting for a commercially available one since. I can't wait until the prices drop!
I haven't been so impressed and inspired by a 3D printer video in years! That is just damn cool!!
Absolutely incredible! One wonders where we will be in 2, 5, 10 years!
You may be late to the 3D printing game but you have one of the coolest toys out there. My 4-year-old 3D printer that I built myself cannot do that. Too bad the Form2 is too expensive for me to afford or else I'd be all over it.
I guess the next qualitative jump will be to 3D print brains with actual neurons. We're not quite there yet, but there are some advances in the area. Simpler organs like liver are already being worked on.
Very curious about the possibility of printing the YBCO superconductor devices. Looking forward to a video testing the efficacy of that process. Do be careful, that does actually sound like some pretty revolutionary IP, and I'd hate to have this video prevent you from taking out any patents.
Novel geometries of superconductors: very interesting concept. It seems like the issue here might be controlling the alignment of the crystalline structure. Perhaps inserting a seed with a known alignment is in order (not sure if that would work with YBCO).
Sounds like there are some applications in MRI-land. Perhaps this could improve the performance and/or manufacturing process for SQUIDs, too. Sky's the limit here - please do follow up with either another video, or, better yet, a startup with a few provisional patents in hand.
Also excellent job with the microfluidics devices. Excited to hear that Verily is actively thinking about applications of that tech, hopefully you guys can pick up where Elizabeth Holmes left off ;)
I almost didn't click this video because I've already seen a lot of 3D printers but when I realized it said high res I decided to check it out and I'm not disappointed. The new Form 3's are actually quite affordable for their specs. Not sure about resin prices since I don't actually have a 3D printer of my own and don't know how much resin I'd need but it looks like that would be where I'd struggle (a high one time cost for the machine is less of an issue than a high cost per part).
What kind of work you do? I just love your channel, the quality and detail on everything... Superb!
The world definitely needs lots and lots of copies of Ben Krasnow's brain.
Ben, you are really amazing. I am always waiting to see your new videos. I believe 3D printing technology (metal, biological material, buildings, ...) will have made our future. In the field of plastic mass production, they made a 3D Printed mold that is used for plastic injection. the main problem of making product especially resin base ones is the price of resins. I haven't seen any open source formulation related to make a resin. I suggest making an open-source resin for this community
Your videos are always so interesting.
Very impressive. Never knew you could print like that with those laser liquid type printers.
Wow Ben actually talking about something he does in his daily job. Thought it was a secret project. Interesting to hear the bits at least :)
i cant wait for 3D printers to become so cheap they are in every house, i think it will be as big of a revolution as the time when everyone was getting PC in their house and internet was becoming a thing
I don't think that everyone will need it for a while, it will be a massive revolution but not something that everyone needs. I am sort of thinking of the services that print things overnight and send them to your house. That is what the majority of people will need because most people don't need to print often enough to warrant a dedicated device in their house. Just my two cents, and entirely up to speculation!
they already are that cheap $200 for a 220x220x220 is pretty good
This is so much cooler than seeing a see of benchees!
Excellent! Very nice solution) I want this printer to my home lab!
The prints this printer creates make this printer a true bargain. WOW
Formlab could not have had a better advertisement than this.
Besides, if they're sponsoring you, it might be worth mentioning that. Same if they arent.
Alexander Sannikov Nah, I am sick of people feeling like they have to say things like, "Formlabs has not sponsors me. I bought this with my own money." People don't believe them when they say that anyways. I like that he didn't say that.
re: Vortex Tube
The thermal conductivity of the plastic is probably a lot less than that of metal. That means that the hot end won't won't get rid of heat as effectively.
It would be less elegant, but you could probably design the vortex tube in pieces, and have the hot air pass through a copper or aluminum tube. If it has fins, so much the better.
It looks like a lot of teething issues have been fixed with the Form2. I would caution anyone against buying a used Form 1+ as a cheaper alternative. It's still a gorgeously made 3D printer, but I think it was very much a beta product. Some people had no issues at all, others could never get it to print reliably (myself included). My own opinions here:
When the 1+ was released, there was no good documentation on post-print care. The instructions we got with the printer were laughably simple. We figured out that we needed to post-cure with UV, but it's only recently that Form developed proper wash and cure stations. These are absolutely necessary for good prints, and manually dunking in a bucket of IPA doesn't cut it. The printers are pretty sensitive to optical issues - dust on the galvos, smudges on the base of the tanks, the inevitable fogging (UV damage by the laser is inevitable, so the tanks are disposable after 2L of printing). Over time the software got better at support design and patches included easy-release tabs on the prints. Old resin will crack tanks - found that out the hard way when it leaked resin into the printing cavity, fortunately missing the important bits.
In short there were a laundry list of little problems which meant that we could never get it working well - I don't think we were ever able to replicate the helix rook that Form provided as a demo print.
I really wanted to love our SLA printer, and on a good day it's easily better than FDM or SLS, but it was so much faff making it work reliably that it's left a sour taste. This seems to be echoed by a number of other 1+ users on the support forum when I was trying to find comparisons. Happy to be proven wrong here, because the results in this video are very enviable.
One of the very first 3-D printers was a laser/liquid....but it was 'inverted' the laser cured the top layer (maybe .002" or so)...the part moved down as it was built....
I saw one at a tool show in 1995.
I love your videos man. Super informative, always learning something new.
This is a really amazing video! I just purchased a form 2 and I'm really interested in doing time delay photography like you're doing here. I'm currently filming for my channel on my phone, so the high end camera might end up being a bit of a barrier for me...
A friend of mine in the 90s had a machine at work that he called "stereo lithography"... this souns like an affordable-budget version of what he described.
If you haven’t yet, check out the movie “Print the Legend”. It was on Netflix. Formlabs is showcased in it.
Lovely. Thank you! Have you tried the pressure ratings in your microfluidic channels? How about a rockonachip? Warping post printing?
Now 3d prind some microfluidic logic gates! Maybe a small ripple carry adder?
"I happen to have quite a few scans of my brain lying around" ...... as one has....
You lead an interesting life ...
Paddy
Read about 3D printing in Wired back in the late 90s. THIS is what was presented (along with a million dollar pricetag) back then, and I've been disappointed with commercial 3D printer offerings ever since.
Finally the 3D printer of my dreams looks affordable!
Man! I have a MRI Scan of my head laying around for years! I never had time to figure out how I can make a stl out of it!
Thanks for that information!
7:24 This is perfect if I really want to know measurements and details. I know exactly where to drill when start experimenting and learning how to lobotomize on myself.
I actually have a brainscan lying around from a study I was a part of many years ago (I got painfully electroshocked in an MRI at random intervals) I also happen to have access to a resin printer of the industrial variety right now. Excellent timing, I just need to get an external CD drive to read the damn thing.
From the looks of it, you could modify such a printer to have a small air port on the moving print bed, so it could stop and blow out the epoxy not set so it doesn't get set later by excess light. This could potentially let you print finer resolution micro-fluidics.
2:53 That's the best looking like glass 3D print I've seen in videos'. How about lenses?
Man, this Ben guy is really smart and inventive, I wish I had his brain.
I’m sitting here going “wow….” Then I realized this video is 4 years old… I wonder how far along they are now.
That is pretty awesome! I wonder exactly how strong the various materials they offer actually measure. I also wonder if the frosted finished products could be made clear with an acetone vapor bath, like the way regular 3D printed stuff can be smoothed out with acetone vapor. If so, that would allow for making clear parts that aren't flat for sanding.
I am convinced you can cast+machine just cavities. You just have to make a water-solvable placeholder for that cavity, then pour epoxy into it, cure it, let the water-solvable plastic dissolve and you'd have the same result.
Obviously this can be done with other materials than I mentioned, it was an example to show of my point.
That's an incredibly slick method. But it appears in the videos that the laser beam(s) fuse the resin at certain locations in the bath.
But how do you stop a light beam at a desired distance? I assume the beam(s) are focused at the desired points to (a) fuse the resin at that point and to (b) avoid fusing resin along the path of the beam(s).
I'd be interested in more info about how Form Labs' method works.
The future is bright on this channel, very cool ideas :-) I'm not sure if you should paint-coat the parts that are going to be used outside to protect them from the sun (UV)?
It's not necessary, UV doesn't break up these resins, it catalyses the crosslinking reaction, so they get better the more UV they get :)
Very cool printer!
Based on This Old Tony's videos on his home-made vortex tube, I'd say your hot side isn't long enough.
As awesome as SLA is, I would still recommend getting a high quality FDM printer for your own shop. Sure, the accuracy isn't the best, but the speed is hard to beat, and you don't always need to print microfluidic structures.
Hi,
Really interesting video I've actually done similar things to your micro fluid experiments on a similar dlp printer (kudo titan 2) for a healthcare company that needed to do scans on heart vessels repeatedly to figure out good settings. I was able to get the smallest part of the vessel down to 100-200 microns.
Have a nice day and keep doing interesting stuff
~Kira
Hii, amazing job. Could you please tell me how do you clean your prints? I want to make some microfluidic devices, and whenever I made channels with diameter smaller than 1 mm, I get the resin stuck inside and the channels are blocked!!
You're one of the most interesting channels i've subbed to... =D
For cup shaped pieces could you not submerge a tube in the resin bath, an snorkel of sorts, to equalize air pressures?
Probably not because it would block the path of the light/optic/laser thing.
He could put the printer in a vacuum chamber, there is no pressure to equalize...
Friend: "why on Earth does this vase have a screw-on bottom?!?" Me: "...reasons."
Michael Scofield
That's good thinkin', but besides the problem of the snorkel blocking the laser, the snorkel tube would also have to be extremely thin because of the way the machine works...
The print is made up of layers, and the way the machine creates these layers is it holds the already-printed portion of the part a fraction of a millimeter above the bottom of the resin tank. The laser then cures that very thin layer between the floor of the tank and the existing part. When the laser is done with the layer, the machine lifts the part, wipes the floor of the tank, and then lowers the part back into the tank (leaving a new gap, which will be where the next layer will be formed). The snorkel would have squeeze through that very thin gap.
I'm not much into the 3d printing scene but I do remember a Ted talk about Carbon3d. It can print very fast. Although I don't know of its precision. Just curious if you heard of it before.
Tesla valve is like a diode for liquids, or gases.
I would think that if you vibrate axially it at the right frequency, it would behave like a pump and never wear out.
May even be useful for an artificial heart.
Good luck with the temperature resistance resin. I have been using it for my prototype. Been auto-calved my parts at 120C for 15 mins and used at room temperature. The trouble is, the part became white, mat, very brittle to the point it break too easily ain't even usable. Have so much problem with it for the pass 6 month back and forth with formlab and they just wont acknowledge the problem. To me, the idea of all the different type of functional resin is amazing, but the technology just ain't quite ready yet. They have also just changed the user guide for resin tanks after years of cracked tank complains. So now you can't have resin stayed inside the resin tank for over a month. I have no idea what to do with mine as I do regular small prints every 1-3 days on each resin tanks. It is a nightmare if I need to clear them out every time. Plus you can told not to pour your resin back into the cartridge, so storing them separately is a pain.
I too have multiple 3D prints of my brain laying around... still haven't found the problem though.
A Promo Code and a Bunch of Savings is alll I need! 🙏👀👌 Each of those parts are definitely as detailed as I would like for 3D Modeled Objects. They're so functional! I don't think the striations caused by an extruding printer could match the structural strength of that lazer Printer either. Just, Wow!, that's so Cool!
Did you ever do a follow-up on trying out making the ceramic form-labs stuff conductive? (I think that's what you were talking about experimenting with at the end of the video?)
would there be any purpose in a 3d printed superconductor? couldn't you just cover the surface of a 3d printed plastic form with superconductor and it would work the same?
Plastic won't stand up to liquid nitrogen, the shrinkage and hardening will tear it apart, that's the issue here.
I can imagine uses for 3d printed superconductors embedded in a suitable 3d printed insulator. There's sensors, switches, and BIG MAGNETS! Muhahahaha.
...and that's just the start.
Strange, this wasnt suggested in my normal feed. Only found it through Patron.
For your negative wind-turbine prints, you should push some LED dies up into the tops and give them hidden beacon lights.
I'm so intrigued by the Forms printer. But, if overhangs require support structure (as mainstream 3d printers do) then how are you printing those embedded passageways inside things? how can there be a 90 degree angle hollow tube inside a cube without needing to break away support structure inside those tiny capillaries... or did you have to do that ?
Yeah, I'm pretty late to the 3D printing game too (as in I haven't bought one yet, but do get some things printed at Shapeways). Being able to print ceramic is mind blowing to me. So I'm up in the air as to do I get Formlabs or some PLA/ABS depositing printer. I would like to print Kynar (Fluorinar) which I've only seen Ultimaker print.
3d print a mold for another attempt at gecko tape
I stunned how good form 2 seems to be in through hole and "inside holes" stuff. I have sparkmaker - its of course no way comparison to form 2 but its also sla - and this stuff gives me most of headaches. Holes smaller than ~ 1.5mm comes out filled with half - cured resin, like a puddy, and you need to push it through (with a small drill bit for example), and hope it got not too hard. I wonder if new anycubic photon 2 has the same problem since paying 2k for form 2 is not an option unfortunately. I was wondering maybe you using ultrasonic cleaner maybe?
Superb demo. Thanks.
I remember being laughed at by my peers when I showed them a 3D printed gear - it was printed via powder process back in the late 1980s! So a big deal back then, they told me it was impossible to print in 3D never mind such a complex part - oh how technology has moved on"
Late? You have 3d printed more cool stuff in 1 video than whole channels in multiple videos.
Hello, I have a query regarding the formlab capabilities; can it be used to print 3 way valves like "3 way stopcock medical valves", the tunnel and the rotary element has to be aligned perfectly to avoid leakage
12:55 your layer names are pretty sweet.
