Ph.D. Chemist Explains 3D Printer Resin
Рет қаралды 462,949
3 жыл бұрынResin SLA printers use ultraviolet light to turn liquid resin into cool solid models- but how!?? We're gonna talk about the ingredients of these resins, we're gonna do an introduction to photopolymerization, we're gonna do some mythbusting, and we'll even talk about chemical safety and disposal!

Hey All! It's been brought to my attention that I conflated a couple of different safety ranking systems- some count up from 1 to 4 and some count down from 4 to 1. With or without the numbers, you can trust the words in the SDS sheets to steer you right. My overall "respect the resin but don't fear the resin" viewpoint remains.

This is the same process they use to make microchips. I used to work in the photolithography area working on Electron microscopes and on the lithography machines. I did the photo resist qualifications as well. Those chemicals were the same as these chemicals on a much much smaller scale. They make patterns that are only microns wide. They hold patterns that are smaller than the wavelengths of light used to expose them. We used a lot of IPA to clean these things up too.

Nice overview. Just to add one important safety tip: If you get resin on your skin, never clean it with alcohol. The alcohol will only dilute the resin with a higher risk of absorbing parts of the resin in your skin. Use paper towels to clean of most resin, wash with water and soap and only after this use a wipe with alcohol if you need to. For safety always wear (safety) glasses and optionally a mask or a full face mask

here's a interesting history: as up to today I believe dental resins are on the 9th generation, one of the biggest problems of resins is resistance to compression, they are quite elastic but compression is the enemy when it comes to biting forces, by the 5th generation 3M fixed a lot of the issues by introducing microclusters which are conglomerates of polymers that form spheres bigger than the normal polymer chain, this created strong points for the resin to anchor on, as soon as other companies started to copy the technology 3M started to lawsuit the other companies as this was their proprietary technology. to fix this company instead of developed micro monomers, which means that they where just bigger monomers to act as anchor this circumventing the microcluster debacle. arguably microclusters is a better technology because they are the same monomers only arranged in a different format and this has been a great development on resin technology. I wander is this particular technology is present in 3D resins, granted you shouldn't squish your miniatures but who knows.

Squishy minis would be fun! I took a tour of the 3M facilities in the St. Paul area, they actually have a science museum there all about materials they've been developing- they've got so many crazy cool technologies that they work on, and one of their big divisions is dental tech.

to be honest about 4 years ago a company designed a burn up resin, this means they could 3D scan a carved tooth plaster model and designed a crown to perfectly fit this model then they just create a negative space in a mold by melting the rest away and filling it later with whatever material you need, pretty neat basically is lost wax method but with a perfect resin model instead of a hand carved one

Thanks so much for this really clear explanation of what is happening with these chemicals. I really struggled with chemistry at school but you’ve made this seem really straightforward.

Every single 3d printer enthousiast should watch this. Damn im amazed that we can watch this for free. THe power of internet and advertisement put to good use. Thank you so much kind sir for sharing your knowledge. You got a subscriber. 10/10 video.

Brent thank you for providing this type of knowledge to so many people. As someone who studied Plastics and Polymer Engineering in school I appreciate you sharing your knowledge on the subject. I dont think I could have done this video in 30 minutes if I were you, I wouldn't have been able to stop!

Thanks for the safety tips Bud. It is darn useful to have someone explain the actual process of dealing with it. Many of the videos I've watched are over stating the dangers and I'm glad to have the straight dope now. Well done!

This was hugely helpful, thank you! I realize that a lot of mini-painters don't necessarily use their prints to make molds but I'm a dice maker... Have you ever looked into the way 3d printed resin and silicone react? I know there's a lot of talk about cure inhibition and ways around that but I would LOVE to actually understand the science

As someone who hated Chemistry in highschool I'm really surprised you got me to stick around for the full thirty minutes! Great as always Goob and thanks for teaching this fellow (Computer Science) scientist something he didn't know!

I find the KZfaq algorithm is working, just bought a resin printer and looking up some things about it. And now I am seeing the mini figure youtubers I been watching is now popping up

Thanks for the clear explaination of complex chemistry in a way that non-chemists can understand. Also thanks for the explanation of how to dispose. Just getting into this space to make part molds from 3D printing and already have to deal with silicones, urethane, epoxies etc, so was stressing about this.

Extremely enjoyable, probably your best video to date! Your chemistry videos are honestly some of the best things on your channel ;) Perhaps we could get a quick-fire round on the chemistry of different glues (the various cements, CA glue, PVA, etc)? Or the mechanisms behind the various paint products such as flow improvers, retarder, thinners, or perhaps how mediums and binders work? Either way, great stuff, hopefully I might have given a little inspiration for new topics with this comment, and look forwards to the next video :) - The physics guy from your pigment video (if you remember!)

Hey thanks! I love making these, it's just a matter of deciding how to package this information as a video. I've got a few timelapse shots of PVA glue drying... but there really isn't too much to say about it! :-)

Thank you for this! Exactly the kind of info I was interested in. I've been going back and forth on the safety of having this in my home--especially related to the toxicity of the fumes. You've eased my mind a bit.
@brettlee4955 3 жыл бұрын
Thanks Brent! I think there are a lot of us that long for more in-depth explanations of the technical details. You did a great job of making the inner workings accessible. As a technical person (who's specialty is NOT chemistry), I thoroughly enjoyed this!
