r/SiliconeMolds

Hey guys. I want to cast a silicone mold in a 3D printed box with a 3d printed master. My master is a fairly intricate model (it has almost no overhangs, but it is an animal with some skin detail that I wish to preserve). I've had some success with PLA before but I want to explore other technologies.

My research led me to SLS Nylon and SLA resin. SLS is more expensive but apparently works with platinum silicone just fine. SLA is cheaper but requires more preparation such as UV treatment and epoxy coating to stop cure inhibition.

Am I right in my assumptions about these materials? Are there other printing technologies or materials I should be considering?
