i'm not sure where else to ask this because this is the closest thing to a general board for crafts.
i'm trying to make injection molds from 3D printed molds. my questions are:
1. what kind of material should i use to make the prints with, that I can use on the lowest end 3D printers, and
2. what can be melted to use with a mold made from such material?
have any of you ever done this?
