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:

@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.
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?
This is excellent. Would you make more chemistry videos please?
@@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.
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.
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!
Hehehe, thanks buddy! :-)
i turned 50 right now, and some youtubers become my new teachers. this is so relaxing to listen too. Brent would be my dreamteacher :)
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!
UNCLE BRENT! Mannnnnnn, 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 love watching both your content so happy that the content community support each other so much mad love to The CrafsMan and Brent
Whoa it's Crafsman
Uncle Brent be steadycraftin
Keep on steady craftin
This is magic. It’s like that DC/Marvel crossover from the 90s. I love these guys.
Hands down the best TED talk I have seen.
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...
What a wild and crazy world! :-)
I feel like Brent could actually teach me to understand chemistry. Like the Mr. Rogers of chemistry.
Hehehe, I'll keep trying! :-)
I definitely got a strong Mr. Rogers vibe somewhere in the middle of the video. Lol
I perceive him more as the Bob Ross of miniature painting.
Me too! I didn`t understand chemistry on the school
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.
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.
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.
@@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.
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
Thanks for the lesson, teach. I am now less dumb :)
That's what I like to hear! ;-)
I feel much dumber to be honest. The stuff you don't know you don't know.
@@emceha but that's timeless wisdom you've acquired, it applies to everything 👍🏻👍🏻
Yet, I still feel stupid.
Samezeez
I was hoping you'd start delving into the chemistry of the hobby. Thrilled to see. Humbly; more please!
more! :-)
@@GoobertownHobbies DEFINITELY more please! Pretty please with a C30H31ClN4O7S cherry on top!
Definitely more!!!! (please)
Yeah great vid. Thank you so much. Also would love more vids on resin, like for example showing professional workflow whith resin printing, or telling something about common myths like overcuring, or savety issues with cured prints. ❤️
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.
yes. I wish I had Brent as a tutor when I was taking Organic Chem as an undergrad.
Research chemist here :)
One further thing to consider (that companies almost *never* list as factors) are the hazards of the *product/waste compounds*, it would be almost impossible to provide/find SDS info for the lovely solution you poured away as waste
As you say, probably not super dangerous, but always best to be overly cautious when handling unknown chemical cocktails
It’s great to see people also discussing responsible disposal :D
I've explained this channel as "Bob Ross does Warhammer", and that comparison becomes more true every video. Love you man
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.
Hehehehehehe :-)
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!
thanks for watchin! :-)
its not often you see someone visibly enjoying conveying complex(ish) information. Thanks goobertown. Thanks for the info, thanks for the smiles :)
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.
This is true. Brent is now for sure my favourite model person :D
Hehehe, hope she approves! Have a great weekend you two :-)
Brent is in his element talking about chemistry. HAHAHAA
oh no... ;-)
You could say he makes chemistry... elementry. his videos are... periodic. I'll go hide now sorry
I see what you did there. :-)
That's very punny.
Cuz SCIENCE!
Neck up - Nerd
Neck Down - Hench
Altogether - Wholesome
Awesome video!
The first rule of ingredients is: You do not talk about ingredients!
Bit late to the whole 3D printing party, but really enjoyed this!
wait wait, you were DOCTOR goober this whole time??
the whole time!
Doctor ~ Mad Scientist ~ not much to tell between the two.
@@Raven.flight oh yeah, there's a big 'ol overlap in that ven diagram
Suspected as much after his explanation of super glue. I have that same molecular model kit btw 😁
@@casperjanowski8187 Orks, I suspect.
This is brilliant. I will have to watch it a few times to really absorb the information, but thank you for making this kind of content.
My man!
My wife really likes you and your channel. She is absolutely not into minis or tabletop or anything like that. But she likes your style and "authenticity"(her words). Her English isn't the best, but she still likes to follow your videos each time I put them on Chromecast.
You and your channel are a true original of TH-cam. I really appreciate that. Keep it up!
Such a great video! The chemistry talk is *infinitely* interesting, and the disposal tips and safety info at the end was perfect. I love this channel so much. Thanks, Brent!
Im a Mechanical Engineering student and from now on this is the only way I accept to learn chemistry. Thanks Dr. Goober
Hahahaha, I better make some more vids! :-)
I'm here for the continuing education myself. Not a lot of chemistry classes in electrical engineering.
Don't forget NileBlue/NileRed and Explosions&Fire.
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.
I've got a few friends who work in that field, it's such crazy awesome stuff!
@@GoobertownHobbies it was fascinating. I was a huge process nerd. It's really cool seeing the technology being commercialized like this. It's a good example of better living through science.
Great job explaining! PhD in oncology here and man I wish all my chemist colleagues are able to explain as clearly as you can! 👏🏼👏🏼
"If you can't explain it simply, you don't understand it well enough"
Dude you should absolutely do relaxation audiobooks. Your voice is making me feel very relaxed. The fact I know how molecular binding work this is just soothing.
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!
Have a super chill and relaxing day! :-)
I relly enjoyed this episode. Wish you could do more (especially Goobertown Roulette) . I listen to Paint Bravely, but, am more visually inclined. I am starting to paint again since my accident, and enjoy the tips and info that you include. Thanks.
Glad you liked it! next episode is a roulette ;-)
Yeeessss! Thank you, Brent (Dr. Goob!)
“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...
I chortled at that line too. And yeah, good stuff!
Ah...what a wonderful video. As a science teacher and one who had apprentices in chemistry laboratories, I got to say, this is inspiring and gives me new ideas on how to break this down. Thank you!
Nice! It can be hard to find the right level for your audience- good luck!! :-)
That is so true. Thanks
Thank you for this delve into the chemical properties of differing resin compounds. I very much appreciate seeing not only the various behaviors of each component in the resin, but the significance of thier inclusion for the process of polymerization.
This is the best video on Resin I've found. Absolutely fantastic and exactly what I was looking for as a primer guide to handling this stuff as I consider getting into resin printing. Thank you for taking the time to publish this.
With a background of product design, 3d printing and model making, there are things I still learn within 20 years and still figuring out some stuff. Here, all info is organized, simple and well explained and truly solving all my dilemmas. That's communication skills at its finest.
Don't know how to thank you enough, a huge huge respect! Spreading the word to the community is the least I can do.
Really been getting into this hobby lately - This explained a lot that I didn't understand. The community has done a great job supporting it across many facets, but the most common thread is "don't pour anything down the drain".
Thank you for this video, really aligned with my current hobby process.
"This isn't even my final form!", Oligomers, probably
Most underrated comment Sir. GG
You make a good teacher.
You got a nice calm voice, friendly demeanor and you know your stuff :)
Finally! Thank you so much for your Hobby Science series. This has helped answer a lot of questions I've had. Having a chemist explain it thoroughly and in a digestible manor to people who don't work in the industry and still providing the information without "dumbing down" is definitely sought after content, perhaps not to a majority of masses, but definitely a community looking for answers. Again, thank you.
Only painting Jesus would make me want to watch a 30 minute chemistry lecture.
muahahahahah
Hey Brent, I just had to say how impressed I was by this video. I'm a teacher by trade and your ability to explain things clearly as well as simply was fantastic! Personally I felt that I wasn't being talked down to and my schema pathways started to reopen back to my days sitting in Senior Level Chemistry at high school. Ka pai!
As a newcomer to resin handling with a 3d resin printer I am grateful that this video shares handling, disposal and understanding to a whole new level. thank you for all the effort you have put into this video. i hope to watch more of them.SUBSCRIBED!
Very cool goober! I just finished my masters in chemistry and found this video so much fun as I clicked on it anticipating someone else but you just continued to talk and it was apparent YOU are the chemistry expert! Great explanation done with plenty of figures, very easy to follow.
I’ve worked in injection molding for over a decade and I think I just learned more in half an hour than I have in all my time actually working with the stuff.
Channel your 90's self and let's talk RADICALS!
Righteous!
Tubular!
Brent, thanks for the intelligent, organized, and clear description of the chemical process. This is just what I've needed.
Just ordered my first resin printer, but I have watched this video many times over the last year or so. Thank you for the knowledge you are imparting here. Your videos on science always make my day.
Brent releasing a long format video that utilises his professional expertise for the benefit and education of the community feels so wholesome. Love the video!
Hehehe, thanks, I'm glad you like it! :-)
I think I've seen this video before, but I like to learn and he's a wonderful teacher.
Absolutely fantastic explanation. I've always struggled with conceptualizing organic chem, so seeing it in such a relatable and interesting frame of reference was awesome. Thank you!
Just got back to this video after recently getting a printer. I looked at my printer's SDS sheet and learned that I am treating it correctly: with respect.
Belated thank you Brent!
I've been really enjoying these videos you've done on exploring the chemistry of the things we use every day in our hobby without even thinking about them, they've been entertaining and informative - what more could you want?! I also love that you've used one of the Combat Wheelchair sculpts as the demo print in this video.
Glad you like these! I love making them :-)
@@GoobertownHobbies you should do a side channel on chemistry. I know I'd sub!
Waiting for my Anycubic Photon. This has helped me so much! Thanks for taking the time to edumacate me!
oooh, have fun! :-)
I'm 12 seconds into this video, and I already wanted to compliment and commend you on the excellent audio production on this video. It really does make a difference, and shows that you care about quality.
Thank you, Brent. I'm an ecologist and the good folks in our Chem department aren't familiar with resin, so i appreciate ypur scientific support😊
this has a thesis-ish quality to it
I'd love to hear more chemistry stuff from you. Great stuff
I’m a senior at RPI getting my undergrad in Chemical Engineering. Seeing another painter whose in the Chem field makes me happy :D .
Brent, THANK YOU so much for presenting the information we need without talking down to us! I deeply appreciate having someone with your body of knowledge in the hobby to give us good info. Nerd on!!
Dr. Goobertown, thanks for all your awesome videos!
I'm not a miniatures guy, but I really appreciate the clarity of your chemical explanation videos. I would totally subscribe to a dedicated channel for that stuff, if you feel so inclined. Keep it up! And thanks.
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!
DUDE!!! By far the best youtuber out there for 3D printing. I just bought a Resin Printer, coming on Saturday and you were the first person to go into depth about resin and about safety. This video deserves more views than it has. Such a good one, my dude! You just got a new subscriber as I got it for doing action figures.
Really enjoyed the video. Makes me want to learn more about hobby supplies. Keep up the great work!!
appreciate the safety segment especially since its kinda hard to find info on resin safety. One thing that would have been awesome is a safety comparison to other household chemicals. How does it compare to dish soap or bleach for example? im still kinda scared to get into resin 3d printing because i got a feeling it could end up being like asbestos where people think its generally safe but it hasnt been explored enough yet to confirm its safety.
Same here! My wife is very paranoid about the fumes. That's why the elegoo 8k is in an ikea enclosure out in the garage! 😂
Just need more activated carbon in my life I guess. 😂
@@helixxharpell For example I recently found out that huffing primer fumes has a noticeable long term impact on your health. I just got a gas mask (which are surprisingly cheap) and havent looked back. Still not eager to start 3d printing due to the excessive time investment needed to get it working how you like tho
@@pepi560Spray fumes have been known to be bad for a very long time.
Like brent mentions in the video as long as you do it in a ventilated area and youre not standing there sniffing it for hours then resin will be fine.
I troubleshoot/work on jet engines and all of this went right over my head, but I could seriously listen to you talk all day.
Thank you for a smooth & fast intro 🙏🙌 so many videos about 3d printing are way over-complex at the beginning
So cool to get an explanation from someone that knows his stuff 😁
Awesomely informative content! Thanks for taking the time to edumacate us all!
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!
I love your laid back attitude
I think I have learned more from you Brent than my highschool chemistry class.
hehehehe :-)
I feel so much more comfortable with my methods of resin handling and waste treatment after watching this.
Thanks a bunch Brent!
Same here. Up until now I've treated resin like it were nitroglycerin.
The waste disposal at the end was really the cherry on top! Fantastic video :)
Love this! It was not only informative but also cleared many open questions I had about resin printers! Keep beeing awesome!
FINALLY. A video that ACTUALLY describes what happens. Thank you
You're welcome! I couldn't find this video either, so I had to make it :-)
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.
Right on! I'm glad this was useful :-)
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!
Brent! This is my first Goobertown chemistry video, but this was super informative and I'm grateful you did this for us. Thank you :)
I can't believe how much fun I had watching this video! Specially not being a chemist I could understand everything and it was extremely educational and... fun! I'd say this is in my top3 of your videos
Hey glad to hear it! :-)
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
i love how excited he got while explaining stuff, you can tell goober really likes this stuff
Your explanation is well done, simple illustrations that explain more complex interactions. thank you for taking the time to share your knowledge with this video.
Listening to this guy, I always thought "He is way smarter than I am, I am sure of it." After finding out that you're Dr. Goober, I have been proven correct.
;-)
Brent taught me more about chemistry in 30 minutes than all of public school did
I'm doing my part! Glad it was educational :-)
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.
And the silly pictures actually made it an 11/10 video for me =).
Thank you for the thorough and accurate handling of so many topics!
Thank you so much for all your videos! I really enjoy them :)

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
I remove it by soaking my hands in Xylene witch works great. Etanol is cancerogenic so I try stay away from it.
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.
Thanks Doc. The chemistry in this video, and your excellent presentation ignited a: "omg I was awesome at chemistry and somehow forgot that fact .. " and the level of concepts you presented was eye opening. I'm in my 40s, last chemistry lesson was in high school. Thanks again.
From one chemist to another, thank you for this video!
“Very long name that ends in acrylate”

Thanks for the breakdown of proper disposal at the end! Very helpful.
great video's I love how in depth you explain things same with your paint solvent and glue vids. thx.
For alcohol and resin.Leave the post cleaning solution out in the light and then filter. Some polymerization will occur which will allow the filter to catch the resin.
i feel more educated while enjoying hobby. keep it coming!
This video truly gave me more confidence in getting going in printing - Very thorough and clear! Thank you!
Thanks! Your video was so helpful for me to understand more about the resin, polymerisation and safety issues! Very clear video!!
