/diy/ - Do It Yourself

My friend had a better idea: have a tropical fruit, and put a jellyfish in it at the same time. For this ill need to save the soft silicone, so now i just used silicone caulk.

I incrementally filled both halves and joined them. Im really hoping the opening will go smoothly. Ill have to do post finish anyway because of the layer lines.

Usually silicone caulk (white silicone didnt, transparent did) releases easily from PLA, but the lines are a problem. Spreading wax with hot air at 150-160C can hide the lines and it releases silicone chalk. I tried epoxy but this silicone stuck to it very good. Didnt try urethane coating tho.

Smooth-on dragon skin released from everything so i can use epoxy to coat the molds to cover the lines for the fruit jellyfish.
