PhD in additive biofabrication here (basically cell biology + additive manufacturing + polymer chemistry)- what your doing here is thermal curing of unreacted monomer groups in the polymer. There is something called a degree of conversion, even in a solid "cured" polymer there is still a high level of unreacted monomer groups trapped. For all intents and purposes this is fine but applying heat leads to thermal curing of some of these trapped monomers and essentially "cures more" hence higher rigidity. You can even go so far as to heat in a vacuum oven under intense heat and pressure to a degree that actually evaporates any trapped monomer Depending on the monomer of course). I've done this before with on top of more aggressive solvents such as (PGMEA) in order to eliminate any unreacted monomer groups that would be toxic inside a human body in order to make experimental polymer implants biocompatible. Be aware that the more you cook you do eventually damage the macro structure of the polymer and it leads to extreme brittleness. A little heat (60-80 C)along with UV is the best curing option without going too extreme, they even sell UV ovens for this purpose (mostly for dentistry) but they can be a bit expensive for a hobbyist. Also always ventilate these fumes.

This is great! Thank you for taking the time to experiment with the material.

Just to add, the HERC Flex resin is specifically designed for thermal curing without cracking or degrading. This process allows you to fully cure the material and produce a non-cytotoxic part, greatly expanding its functionality. As a result, it can be used in applications where typical resins wouldn’t be suitable.

It's important to note that light alone cannot achieve a full cure in 3D photopolymer; thermal curing is essential for a complete and thorough cure. Please be aware that most resins are not designed for thermal curing and may be damaged if subjected to heat.

It's a coincidence that you uploaded this. I was just looking for this info to see if I could do some repair work using sculpey, but wasn't sure if my prints would hold up to the heat! Thanks!

When I tried baking a hollowed print it caused it to shatter after less then an hour. even at just 170f. there were plenty of holes to let out air but the heat seemed to make the whole print soft and the supports inside either expanded or contracted breaking the entire print

[colesutra]

I’m looking forward to getting my hands on some of that Hercules resin. Curious about how well it takes paint, and how well the flexibility is retained after a few months. And curious about how well it handles hollowed out prints.

[AcoylteKraven]

18:06- Well, that answers my question! It’s still very cool and I’ll have to figure out how much a toaster oven costs and if I can get one for cheaper?!? But my real first thought was, how good is paint going to stick to it?!? I mean the flexibility sounds great……. until you remember that the paint you plan on putting on it might also need to be able to do that also!?! It almost seems like even if the paint sticks perfectly to this, after a few weeks you are going to have a bunch of cracks at each “bendy” spot!?!

[AtlasD]

Thank you so much for sharing this Jessy! Really appreciate it.

[Ellery-USA]

Just curious if you tried baking a larger model that is hollowed. Would that help cure the inside?

[hightde]

I find it really interesting how much talk there is over the tilt vat feature of the Elegoo's. I always wondered if there was an actual benefit to the tilting vat feature of the Prusa resin printer but it never really got talked about much. What a difference price point makes!

[JPWestmas]

Yes!!! Super glad to see this kind of progress.

[DonsArtnGames]

1:26 Okay it has a nice smell... is the smell toxic? What kind of VOC is it putting out?

[mrnlce]

How does it compare to tenacious? And can you add it to other resins to improve the resilience of a cheaper resin?
Great video. Keep up the good work.

I got invited to rapid tct by shining3d, but I already had plans for 2 professional events for the games industry, 1 Caextreme classic arcade and pinball convention, and a family vacation this year. So, my bank account is currently screaming between that and new 3D printer related purchases.

I could have met the man, the myth, the legend, Uncle Jessy himself. I guess I will have to settle for the fact that Uncle Jesse from Full House used to come to my family Christmas parties back in high school when he dated my cousin.😂

I work at a college as a 3d art studio specialist, and some of my students started calling me Uncle Marcus out of nowhere, but I took it as a compliment.

I finally ordered an elegoo resin printer instead of my usual go to brands.

Thanks for all of the fun and informative videos!

I bought a cheap food dehydrator. After I wash in ipa, I let the models air dry, then put them in the food dehydrator for a few hours. Then cure em. My prints have never come out better

[GeekDetour]

2:43 You are getting addicted to this thing, @UncleJessy :) Soon you will enjoy the smell of all resins, ha ha ha.

[kaijuk]

I bought the Elegoo Jupiter SE and I have 5kg of Jayo standard grey resin but I've heard bad things about the resin such as it's crap and really brittle. I have been told that mixing 10% of Siraya's tenacious resin with 90% Joya it fixes the issues making t hem stronger and more flexible. Fingers 🤞🏻

[leedunning]

I can see the more flexible resin being great for small projects, but it seems that the larger the print, especially if it has wings, outthrust arms with weapons, or a heavy figure perched on a slim support, the weight will cause it to sag over time and also make it more prone to toppling over.

[pingbot]

new video! Just ordered my S4U a week ago so i look forward to it. Maybe im confused but on your S4 it looks like u forgot to remove the screen protector?

[DJapan]

I used the resin from My Mini Factory and it was TOO soft after the print. I washed it and let it sit to dry only to find the parts were drooping before they could be cured.

[tristanc]

I built a toaster-curer but ran into a few problems. I got a turntable, but they kept warping and cracking under the heat.
I may punch a hole through the bottom and keep the motor outside the oven.
