You should used the form3 resin in elegoo. The printers are the same in function so if elegoo slicer setting are the same for the form3 resin. you should get the same results. Test it.
I was going to comment the same thing. Apart from the fancy refill there both just UV LEDS, so the only real difference should be in the resin you use.
It isn't really that easy, since the Form3 is an laser-based printer (not UV LED+LCD), the resin is much less sensitive and requires higher activation energy than the mSLA resin for the elegoo. If it does work, it will be very very slow.
@@QuintBUILDs you shouldn't really need to do any fancy calibration, just make sure your exposure time is within the range on the bottle and you're good to go.
MSLA 3D printers like Elegoo/Anycubic printers also have tough resin options that can take up real-world abuses. We are happy to send you our Nylon-Like Tough and Tenacious resin for making impact-resistant parts for comparison.
Pro tip about holding water: process FDM-printed parts with a dissolver (f.e. ABS with acetone) and they become completely water / air tight. I've made many hi-pressure manifolds and valves that way.
Also, play with layer height. Most people think smaller layers = better, but tests show that's not the case (check out CNC Kitchen, for example). Smaller layers may result in higher resolution prints, but layer adhesion is worse, which is where you get water leaking. Been printing water-tight parts on an Ender 3 for ages without any post processing.
I prefer PETG, With the Highest temp I can for this type of part, with just a shade of extra flow if it's not too detrimental to the part. It holds water every time. In vase mode, I'm not sure, but with multiple walls yes. Also I think some parts can be annealed if necessary thoigh I've never done it
Great, video. Looks like it took 100+hrs to shoot and edit. I hated science and math growing up. If you were my teacher in school, I might be a whole lot smarter. Keep up the good work!
Quint, I love your videos. They bring me back to the lessons I learned my engineering courses. You are so great at explaining the theories and showing their applications in interesting ways. Keep up the great work and thank you!

Awesome, thanks! It really is my favorite 3D printer. Just last night my son and I ran timing pulleys printed in Clear up to 5,500 RPM. They handled it no sweat!
Looks like your printers and cardridges are unreliable at best and dont work at all at worst.. Unfortunately i'll have to remove your Printer from the collection i am eyeballing at the moment.. Elegoo it is then. A Buddy has no issues with Elegoo, even if requiring more manual work e.g. when refilling.. totally worth less money spent and less frustration. And with the cardridge-style we have the same issues as with normal printers too.. the printer says its empty when its not, the company can make the material extremly expensive to buy and even refuse to print with other types of resin not from that company.. Really bad practises.. pure evil! Seems like you went the same route. Full on capitalism!
@@QuintBUILDs You cant reenact the printer scene from office space with the formlabs pinter and then say they have a great product dude. Thats like saying me and my children are going to straight up MURDER you and when you are dead i will drag your insides behind me and then saying you love them. This is why they are in your comment section.. becouse they are afraid. And rightly so.. becouse how can they ever hope to recover from a diss THAT HARD. This guy is not messing around here formlabs.. you have been warned.
I'd love to see you experiment with more, cheap resins in the Elegoo. Things like Siraya Tech's stronger resins are very popular to mix into various ABS-like resins to increase durability and strength. I think it'd also be interesting to to experiment with different printing orientations. Printing the pieces on their side (as opposed to vertically) could increase their strength further. Layer de-lamination is less of an issue with resin versus FDM but it's still inherently present in the manufacturing method. Great video as always!
Fun fact, I obtain similar results on a 200 USD second hand Core XY printer that I modified to suit my needs, prinitng in Polycarbonate, PLA, and other materials like PPS PEI etc. The trick to not spend 5 gran for a printer and 200 bucks per liter of resin is the after print rebake in popcorn salt remelting at some 10 Celsius under the printing temperature, and keeping it so for a few hours than let it cool over the night, that eliminates in the semiliquid state (guiyii state?) all micro bubles of gas (mainly air) from the FDM printed parts allowing the polymers to weld into eacother without the part changing shape, well something changes but insuficcient to make the part usless from a parametric point of view. In the end I obtain same quality (nearly) as injection moulded parts, without the perfect aspect because... 3D printed.
Love the video. I use a Form 2 and a Form 3L at work and love them. Print quality is excellent and so easy to use. I agree with some of the other commenters that the resin is really expensive. A couple tips on getting the raft off the build plate: Use a thicker raft (2.5-3mm), soak the build plate in the alcohol for longer (once the parts are removed) or in a worst case situation, throw the build plate in the cure tank for 10-15 minutes on medium heat.
I saw a review of this printer and the reviewer had the exact same problem and Formlabs advised to manually fill and then cut a slit in the bottle, If I had bought that it would be going back to source I have a Voxelab Proxima Mono 4K for the very little resin printing I do and its a great printer, the quality is top notch and I cant see the layer lines without a microscope and the build plate is quite big at 8.9", I printed a lid on one of my FDM printers that turns the vat into a bottle to pour the left over resin back into the bottle, no mess whatsoever, the lid was water tight after printing but just to be safe I gave it a thin coat of the resin and cured it with a UV torch I have a tray that fits the whole of my workbench so if I did spill any resin it would not go far and is easily wiped up, the next project is a fume cupboard, I have low odor resin but I also bought some ABS like stronger resin and that is quite whiffy and the printer has to go in the garage when I use that
So cool that im taking my materials mechanics class this semester and able to apply/understand what is being said in this video. Very informative and a great visual example of what's being taught to me at school, thank you!
Material Scientist here, Tensile test pieces are indeed usually round and also have a narrowed part in the middle to ensure where the part breaks. for what you are trying for please increase the grabbing ends to be thicker ensuring you break in the middle or go for a wishbone that is much thinner but the same design as what you have. The main thing is you want to control the break. This is why most pieces are threaded to make sure you are not creating stressors but creating a good grip. For flat objects, you have to make sure your clamps can hold more than what you are testing but still be flat and I would have something between the flat metal and the plastic piece with a higher coefficient of friction.
This video explains exactly what a department at my work does for testing. With the items that I make for them to test the strength with. Thank you, I'm going to be sending this to people in my area so they can understand what happens to what we make.
This video really helped me understand a number of aspects of 3D printers. I have been thinking of buying one, however with so many price variations, and not knowing enough about them; I didn't know if the dearer ones were worth the extra spend. Nor did I really understand the different types. Thanks for helping me not only be more informed, but also show me what to look for. in a 3-D printer.
I have those same rims on my 86 f250. They were pitted out so I sanded them down filler primer, sanded, then painted them to a similar silver. Originally polished aluminum, American racing rims. Your truck looks nice.
It's too bad we haven't figured out a way to do resin printing with long fiber reinforcement yet. Imagine how strong we could make parts then! I'm also really impressed with the strength of that resin. I had always heard that you use FDM for parts that need to be strong and durable, and resin for parts that sit on a shelf and look pretty. Even if FDM IS stronger and more durable, this certainly shows that resin parts aren't just fragile things that will be destroyed the moment you look at them crosseyed.
I would like to recommend adding links in your description to the products used. Some of my favorite print channels do this and it helps a lot. Especially when you find products you like. I love the kind of information your channel provides and think taking this step would bump it up just another notch for us viewers. I believe you can even monetize this to make it more affordable to make even more content.
I started my career as a metallurgical lab technician. For three years, I made my living breaking steel wire. Breaks in the jaw were common and frustrating. What really amazed me, though was that I could influence the location of the break with just the heat of my fingertips. Simply holding my fingers on the sample for a few seconds was enough to ensure that the wire would break where touched. (Obviously, these tests didn't go in the records).
Man, your reenactment of the Office Space printer scene with your kids was just...amazing. Your kids are already doing some incredible things now. It's exiting to know what they will be up to in the future!
Polarized glasses, you get those when you go to a 3D movie! One lense is vertically and the other is horizontally, letting the image enter the left and right eye separately. If ever you get your hands on those hold them up to your phone or monitor- it's cool :D
with FDM you can make parts that can hold water, with the right settings. I build a watercanon which is tested at a waterpressure of 10 bar and i had no leak and that with pla
This resin looks strong ! But when you compared it against your FDM printer you should have used more materials than just ABS, since ABS is far from being the strongest, even the common PLA is near to twice as strong in this specific test. And by the way the youtube channel CNCkitchen has an interesting setup to test the strength of 3D prints ! For example in the tensile test he made samples with rounded edges and rounded supports on his machine to reduce the stress due to a potential misalignment
Hey Quint, could you discuss the setup more? How is the press setup for pulling the load? Is it a compression test? Just having a hard time understanding how you're able to pull with the press.
Had you considered designing groves in the part to line up with the ridges in the clamp so you could prevent slipping without having to apply so much squeeze? ;-) Nice video as always. Keep up the great content.
Great video! Couple of questions" 1) in the formlabs clear resin spec sheet, where it says 'green' does it mean as is just taken out of the printer (and washed of course), but no additional UV curing? (I hope it's not some kind of clear-green resin :)) 1.A) if so, then could we increase (and how much) the exposure time during printing to achieve higher strength before (or without) post-curing? My point is that with post-curing sometime uv light can't get deeper in the model, if it's not very clear, but while printing each pixel in each layer is exposed to uv for whatever time we set. 2) Is saw in a comment of your below "ran timing pulleys printed in Clear up to 5,500 RPM". Could you specify what's the radius of these pulleys? I'm considering building DIY centrifuge (a waste-oil processing one, that the fluid to be cleaned is poured in continuously and only the lightest one flows over an edge, meaning that any heavier particles would settle on the sides of the centrifuge drum), and I have some rough guestimates on what g-forces I should be able to reach with 140mm diameter spinning drum (the largest a Mars 3 can print in one piece). I'm going to use a Dremel that reaches up to 35000 RPM, so that shouldn't be a problem. I assume the material strength is going to be the limiting factor, but before making torture tests I'd like to get the proper resins and have somewhat accurate expectations. Any info would be greatly appreciated! :)
To defend the metric system: 1 Mega Newton/m^2 is the same as 1N/mm^2. N and mm are commonly used in engineering (because we do not have that big sticks either). And did I get it right that you use a unit of weight (lbs) to describe a force here? Fine on earth but it might get tricky on the moon
10:16 could it be so much stronger cause it can completely cure? Elegoo resin is not transparent so I’ve will not reach the core. Your exposure time when printing are the only uv hitting that center.
You should've tested that Formlabs resin in the Elegoo printer to see if you could get parts that matched the strength of the Formlabs machine while using the MUCH cheaper printer. I'm quite sure there are slicer settings out there somewhere for that resin on other machines.
Agreed it LOOKS taught, but watch when I check the right rear tire. The whole bronco sways and you can see the chain swing loosely. Should have reached over and touched it but I was out of my mind with excitement! 😜
I use a polariscope to check stresses in my glass everyday. It's very difficult to anneal coe33 solid objects over 100mm sometimes taking a few days to a week in the kiln. Seeing the stress helps visualize the annealing process. Look at a clear garbage bag ripping. It has a crazy stress pattern.
9:49 seems like these were printed standing? So in z-direction? This makes the part weaker by ~50% because you do not use the elastic capcity of the material since you put stress on the bonding area between the layers. Since the little meltzone between two layers is way weaker than the material itself, you will get bad results which is why I look very closeley at my CAD-design and check where forces attack and how the object/part is going to be stressed to most. According to my findings I print the part lying down so that I always stress the part in the direction of x and y. I try to avoid stressing in z-direction. If I have a part that will experience positive pressure (like something standing on it or the part being a bearing of some sort) I print it differently since the Infill will take most of the load and compressing materials is always harder than ripping them apart. I really like your video, I think resin 3D printing is almost a bit cooler than FDM, especially for technical solutions since the print accuracy is higher so you can achieve closer tolerances, but all the chemicals and necessary post processing is a bit offsetting :(
@@QuintBUILDs Yeah I saw that, but wondered why you showed the parts which where printed in z-direction. Got a bit confused there. Thanks for the answer!
Great Video! this is my first time on your channel, so glad I found it. What about so called engineering resins on the Elegoo? Formlabs resins are a small fortune, and theres likely no preconfigured settings or profile for them on the cheap chinese printers like Elegoo. Have you tried the Korean brand resin 3DMaterials? they have a SuperPCS resin that apparently can handle almost 7,000psi tensile strength.
I think you're right about the wavelength. I wonder how important the flexible formlabs window is though. They lift it up against the print with each pass of the laser as opposed to letting the whole layer stick to the FEP. At least that's my understanding from the animations I've seen.
If you printed, or even machined in matching grooves to the grippers, you wouldn't need to clamp them so hard? Or, would then the threads be the weakest link? Very cool video, and educational.
You should have done wired Ethernet - always more reliable than WiFi. Also, you probably got a bite valve without the normal sized opening. Close the top vent and flip it over, and work the bite valve until the slit is all the way across it. You might need to start it a bit in the center with a sharp knife. This happens regularly with new material tanks, and is also discussed on the Formlabs forums.
Regular printers with extruded plastics can be made MUCH stronger by putting them in the oven so the layers can completely fuse together. To prevent deformation, you can surround it in fine sand then course. So it does melt but has no where to go. There's maybe 3 to 8 percent shrinkage depending on what plastic you use.
Can you please tell me if the Formlabs resin will work in the Elegoo printer? And if possible do a test of strength between one printed on the Formlabs printer using Formlabs resin?
Form3 and Saturn would be my perfect setup. Instead I have 2 Saturns. I would use the Form3 for work, I'm a goldsmith and jeweler. The Saturn is great for hobbies.

It isn't really that easy, since the Form3 is an laser-based printer (not UV LED+LCD), the resin is much less sensitive and requires higher activation energy than the mSLA resin for the elegoo.

Why you dont use the whole "pipe" (fallrohr) from the gutter to the bottom for that syphon?

Couple of questions"
1) in the formlabs clear resin spec sheet, where it says 'green' does it mean as is just taken out of the printer (and washed of course), but no additional UV curing?
(I hope it's not some kind of clear-green resin :))
1.A) if so, then could we increase (and how much) the exposure time during printing to achieve higher strength before (or without) post-curing?

2) Is saw in a comment of your below "ran timing pulleys printed in Clear up to 5,500 RPM".
Could you specify what's the radius of these pulleys?
I'm considering building DIY centrifuge (a waste-oil processing one, that the fluid to be cleaned is poured in continuously and only the lightest one flows over an edge, meaning that any heavier particles would settle on the sides of the centrifuge drum), and I have some rough guestimates on what g-forces I should be able to reach with 140mm diameter spinning drum (the largest a Mars 3 can print in one piece).
I'm going to use a Dremel that reaches up to 35000 RPM, so that shouldn't be a problem. I assume the material strength is going to be the limiting factor, but before making torture tests I'd like to get the proper resins and have somewhat accurate expectations.
Any info would be greatly appreciated! :)
To defend the metric system: 1 Mega Newton/m^2 is the same as 1N/mm^2.
N and mm are commonly used in engineering (because we do not have that big sticks either). And did I get it right that you use a unit of weight (lbs) to describe a force here? Fine on earth but it might get tricky on the moon
i think strictly speaking, they use a modified version called pound-force, (lbf) which is normalised for relative gravity. still prefer metric.
10:16 could it be so much stronger cause it can completely cure? Elegoo resin is not transparent so I’ve will not reach the core. Your exposure time when printing are the only uv hitting that center.
You should've tested that Formlabs resin in the Elegoo printer to see if you could get parts that matched the strength of the Formlabs machine while using the MUCH cheaper printer. I'm quite sure there are slicer settings out there somewhere for that resin on other machines.
The chain looks taunt so is the 3D print solely holding up the truck?
Agreed it LOOKS taught, but watch when I check the right rear tire. The whole bronco sways and you can see the chain swing loosely. Should have reached over and touched it but I was out of my mind with excitement! 😜
you earned my sub for sure!
I use a polariscope to check stresses in my glass everyday. It's very difficult to anneal coe33 solid objects over 100mm sometimes taking a few days to a week in the kiln. Seeing the stress helps visualize the annealing process. Look at a clear garbage bag ripping. It has a crazy stress pattern.
Hilarious, this mix of GTA violence and product testing. Great at 1:30 am. Thank you. 🤣
You're welcome! 😂
I do this type of stuff at work and I love it🤙🏽
9:49 seems like these were printed standing? So in z-direction?
This makes the part weaker by ~50% because you do not use the elastic capcity of the material since you put stress on the bonding area between the layers. Since the little meltzone between two layers is way weaker than the material itself, you will get bad results which is why I look very closeley at my CAD-design and check where forces attack and how the object/part is going to be stressed to most.
According to my findings I print the part lying down so that I always stress the part in the direction of x and y. I try to avoid stressing in z-direction.
If I have a part that will experience positive pressure (like something standing on it or the part being a bearing of some sort) I print it differently since the Infill will take most of the load and compressing materials is always harder than ripping them apart.
I really like your video, I think resin 3D printing is almost a bit cooler than FDM, especially for technical solutions since the print accuracy is higher so you can achieve closer tolerances, but all the chemicals and necessary post processing is a bit offsetting :(
I printed everything in all orientations at least once, but those samples were printed lying down (watch the timelapse again).
@@QuintBUILDs Yeah I saw that, but wondered why you showed the parts which where printed in z-direction. Got a bit confused there.
Thanks for the answer!
Stellar content!
The office space skit made me subscribe.
I’m curious how the Prusa SL1 compares to these options
you were able to use the formlabs resin in the elegoo saturn?
Didn't try it, no.
Great Video! this is my first time on your channel, so glad I found it. What about so called engineering resins on the Elegoo? Formlabs resins are a small fortune, and theres likely no preconfigured settings or profile for them on the cheap chinese printers like Elegoo. Have you tried the Korean brand resin 3DMaterials? they have a SuperPCS resin that apparently can handle almost 7,000psi tensile strength.
Would liked to have seen you print with the Formlabs resin in the Elegoo. I believe they are both 405nm.
I think you're right about the wavelength. I wonder how important the flexible formlabs window is though. They lift it up against the print with each pass of the laser as opposed to letting the whole layer stick to the FEP. At least that's my understanding from the animations I've seen.
If you printed, or even machined in matching grooves to the grippers, you wouldn't need to clamp them so hard? Or, would then the threads be the weakest link?
Very cool video, and educational.
You should have done wired Ethernet - always more reliable than WiFi. Also, you probably got a bite valve without the normal sized opening. Close the top vent and flip it over, and work the bite valve until the slit is all the way across it. You might need to start it a bit in the center with a sharp knife. This happens regularly with new material tanks, and is also discussed on the Formlabs forums.
Regular printers with extruded plastics can be made MUCH stronger by putting them in the oven so the layers can completely fuse together. To prevent deformation, you can surround it in fine sand then course. So it does melt but has no where to go. There's maybe 3 to 8 percent shrinkage depending on what plastic you use.
Id be very interested to get a copy of your tensile test rig in 3D.
Thank you
The whole tester, not just the samples?
1 MPa is also 1 N per mm2, which sounds more familiar 🤙🏼
I'd love to see if your stress visualization worked on a Prince Rupert Drop. I think showing the stresses as the tail is broken might be really cool
Totally should work! 👍
We have a form 3 at work and haven't had any issues with it. Sorry you've had issues with yours
First resin printer was a Mars2. Never had an issue.
Can you please tell me if the Formlabs resin will work in the Elegoo printer? And if possible do a test of strength between one printed on the Formlabs printer using Formlabs resin?
That segway was BRILLIANT
I see what ya did there... 😂
Great content.
What software using to do design
Wonder if it would be different if you printed it horizontal vs vertical like you did.
Tried it but didn't make the video. No difference. Much bigger difference in fdm printers.
@@QuintBUILDs that's intriguing. I guess the layer lines fuse together stronger. Good to know.
Man, your such a cool dad!!
I'm assuming the formlabs polymer resin is a different wavelength than the elegoo so it's incompatible and proprietary?
Y'know I'll have to look that up. They publish the wavelength of their laser.
@@QuintBUILDs
I guess I could look it up 😆 thought you might know off top of your head.
Now will the elegoo print the formlab resin
Form3 and Saturn would be my perfect setup.
Instead I have 2 Saturns.
I would use the Form3 for work, I'm a goldsmith and jeweler.
The Saturn is great for hobbies.
