what heat should my plastic be able to withstand without getting melty? idk if 80 degrees Celsius is good enough, might have to look at other materials

The theoretical maximum will to heat without complete melting will be the glass transition temperature (https://www.sigmaaldrich.com/content/dam/sigma-aldrich/docs/Aldrich/General_Information/thermal_transitions_of_homopolymers.pdf). This will be unique for the polymer you are using, and can vary with additives, molecular weight distribution, copolymers, etc. I suggest looking up the Tg of your specific polymer and staying below that to avoid deformation. If you go above Tm you are completely screwed, so don't do that. If you bought virgin polymer from a reliable source, there will probably be Tg and Tm listed on the packaging or with the properties sheet.

why is it gonna be at 80C?

came for dolly's... disappointed

Me too :(

idk lol i doubt it ever would, but i was thinking how hot do peoples rigs get, and what if a random keycap was on the rig without proper cooling and melted. kinda an absurd scenario i guess

I'm so entirely confused.

i think you need to update your thread title. Also got confused on the relevance of your title to your question. You might get better answers with a descriptive title :thumb:
