I’ve been testing different ways to make molds for resin. Insulation foam doesn’t really work. Resin heats when setting causing the foam to melt.

Resin Jackrabbit
Few months back I sent a smaller printed Jackrabbit to a friend who made a silicone mold from the object. After acquiring some new resin, I tried a cast with the new resin. The mold picked up everything from the surface of the 3D printed object, hence the ridges and the bubbles are from a lack of tamping when casting.
The new resin I found has worked well, and can be found outside of craft stores. The Famowood Gloss Oil-Based Polyurethane, which is intended for finishing flooring and tables. However, it’s the same components and works with resin dyes meant for craft polyurethane.
Happy Casting!
