I want to make a model out of resin. How should I start?

Epoxy resin is mainly used to make resin models, and its casting models are often used. In short, the pouring process has the following processes:

1. The original can be made of plexiglass or ABS.

2. The mold can be made of silica gel or gypsum, the former has good casting effect. The tool used is a vacuum pump (without a vacuum pump, there will be bubbles).

3. open the mold.

4. Casting parts with epoxy resin. The tools used are oven, curing agent and balance scale.
