Ph.D. Chemist Explains 3D Printer Resin

[@GoobertownHobbies]

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.

@Tzuede Off the Cuff Check with your Waste Management organization. In my town they have one Saturday a month you are can drop off hazardous substances like old resin, it's something they don't advertise a lot, but you can found out pretty easy if you call.

[@einekleinerockmusic8152]

question brett: I live in a studio flat with limited ventilation options at the moment, but I brought my Mars with me because I read enough about the risks that i thought I could work something out. Is this a dangerous line of thinking? Should i permanently have my windows open?

[@calchen6603]

This is excellent. Would you make more chemistry videos please?

[@tudoroltean3183]

@@einekleinerockmusic8152 there are 3rd party designs for activated carbon filters and/or exhaust tubes to vent all the fumes outside without having to keep the window open.

[@elofgren1]

Sort of channeling the same feeling you being a chemist, I find myself working with resin sort of the same way I used to work in microbio labs. Always assuming surfaces are "hot", trying to minimize stray messes even if the rest of my hobby space is in shambles, etc.

[@mtgtraininggrounds6879]

Hi Brent! Chemical Engineer here, and I want to thank you for this video. You've done what many teachers struggle to, tie complicated science to everyday fun (in this case a hobby we viewers all share). Bravo you beautiful goober!

I would really love to see a new video talking about water-washable resins and how they differ chemically from traditional resins that are washed with alcohol.

[@zapl80]

Probably not much. Would imagine the difference is probably just that ingredients are more water soluble so the sticky mess can be washed off with water. They should still not go down the sink or your throat because they aren't any more healthy because of that.

[@ralfsstuff]

Pretty much what I've learned. The only thing you get rid of by using them is the alcohol. Other than that they're supposedly just as toxic.

[@seitenryu6844]

​@@ralfsstuffAt least you save the expense and small hazard of alcohol. You don't have to careful how you much use to clean your part either.

[@bruceottenberg373]

yes. I wish I had Brent as a tutor when I was taking Organic Chem as an undergrad.

[@NicolasSalencPBP]

Hey, awesome video. Quick question: Once the part has been printed, you're supposed to shine a UV light on it to fully harden the part. How does an opaque resin print get cured on the inside since the UV is only hitting the surface of the part? Wouldn't the pigment block the UV? Would transparent resin be more effective at curing evenly? Thanks

[@Triskelle420]

its not often you see someone visibly enjoying conveying complex(ish) information. Thanks goobertown. Thanks for the info, thanks for the smiles :)

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.

First post for a first time viewer. Thank you for this post I have been blessed with! I have recently retired as a HASWAPER in California, USA. I am also been attracted to 3D printing and have avoided liquid resins because of my industry sponsored training. With Your down-to-earth explanations of the resins and their reaction process, I am willing to explore this fantastic process! The finer detail achievable can be a powerful draw! Currently I accept granulated resins and process them into a filament that feeds my print heads, a cost reduction of 90%, the last time I checked, and I get to choose the colors I am working with. Extending my hobby dollars while i was working was paramount! Now that I have a better understanding of the liquid Polymer process from your explanations, I am willing to delve into this side of the 'Additive Machining Process' and buy a liquid based 3D printer to augment my current fleet of filament printers. May the final days of the 2022 season bestow lasting blessings to all that respond to this post. 🦊Riki2Tails

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

Brent, thanks for the intelligent, organized, and clear description of the chemical process. This is just what I've needed.

[@1polvomagico]

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.

[@GoobertownHobbies]

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.

[@enveritas4948]

Imagine the look on your dentist face when you show up with a pre-printed crown or tooth implant with an imperial aquilla on it. Can't wait for dental grade 3D printer resin.

[@1polvomagico]

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

you could totally make a tooth crown with an aquilla incrustation now, just need to find a lab technician dextrous enough to craft it

A question: If one were to shine UV light on the used IPA, would the leftover resin polymerize and be easier to filter out? Would that be a feasible option?

Not really. It will polymerize but depending on how much resin is mixed in to the IPA it will just create a hard wall with a liquid inside. It also smells to high heaven.

Niceeee! I actually printed one at ~90% for a good size for typical size dnd squares. (of course I've also printed big ones!!)

@@GoobertownHobbies Heroic scale is where it's at, it is hard to squeeze the larger models onto some of the 30mm bases. also thankyou for the educational videos, the previous deep dive into pigments changed how i see colour.
