Ph.D. Chemist Explains 3D Printer Resin

Resin 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!

More Goobertown!

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. For more info:

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!

[matthewrayner]

Goobertown is now both the most wholesome mini painter, as well as the most relaxed chemistry teacher!

Just finished watching it: really educational and well formatted, brilliant video!

[lmccoll]

Is it mean that I just assumed you were just a gooby Goober? Now you're a whole doctor Goober, I dont know what to believe anymore...

[TheCrafsMan]

UNCLE BRENT! you just brought the INFORMATION with this right here! I had to let you know I appreciate how much you put into this.
Top-notch production value, vocal delivery, and comprehensiveness.

P.S. The only PhD I have is my post-hole digger. Bigtime respect to you, sir.

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.

[ThroteCHOP]

I feel like Brent could actually teach me to understand chemistry. Like the Mr. Rogers of chemistry.

[sysiphuspeart]

I was hoping you'd start delving into the chemistry of the hobby. Thrilled to see. Humbly; more please!

[unclewyrmwood]

Thanks for the lesson, teach. I am now less dumb :)

[antongunther]

Honestly I wish you were my organic chem teacher. This was to the point and unintimidating and the friends I showed this too that have no background in chem were able to get it. I'm glad to have someone like you in this hobby space

[justinjohnson]

I learned more about chemistry in this 30min than I have in my entire life. The way you introduced things simply and built on them with the actual science was very easy to make sense of. Thanks for the great video that answered every question I could think of in great depth.

[tyreiraeth]

I've explained this channel as "Bob Ross does Warhammer", and that comparison becomes more true every video. Love you man

[preece]

Normally I watch the painting videos whilst my chemist girlfriend sits and pretends she's interested. Today, she's nodding and providing commentary whilst my head melts. Cheers, Brent! Keep up the good work.

[Nathaivel]

I love how this starts out as a fun and engaging lesson in polymers and stuff I remember from high school and then sharply ramps up to Brent decoding trade secrets of major chemical companies and showing how you can make your own resin out of soybeans, no big deal.

[samhughes]

Wow. This was sitting in my "Watch Later" list for a while, but now I can't believe I didn't give it a go earlier. This was so good!

[ganzgrosseskino]

The first rule of ingredients is: You do not talk about ingredients!

Bit late to the whole 3D printing party, but really enjoyed this!

[yakidHB]

Im a Mechanical Engineering student and from now on this is the only way I accept to learn chemistry. Thanks Dr. Goober

[luigiboi]

Brent is in his element talking about chemistry. HAHAHAA

[XanderSoldaat]

Had to test my blood pressure this morning, and I knew exactly what channel to turn to, to get it down to the rest value in no time. Nothing cures hyper tension than that voice.

Thanks for the super informative, educational, and relaxing video!

“Like in Fight Club...” This magnificent video showcases several of the reasons that you are AWESOME. As someone who really had to slog his way through AP Chemistry in high school and then go get his PhD in the biological sciences because chemistry is too mighty, I appreciate the effortless way you broke this all down for your fellow hobbyists. Many thanks...
