Adventures in epoxy casting part 2

Art, Projects


I’ve done a lot of casting, but all plaster so far. I knew that if I was going to make more complex detailed designs then I would need to move to epoxy plastic casting. In hindsight I should have started with a simpler, one piece mold. I thought that since this shape is basically a ball it would be easier.

  1. Not building a outer mold
  2. Forgot the pour spout in the mold making.
  3. probably should have cast this upside down, to avoid bubbles in the face.
  4. I worried way too much about getting all the angles perfect on the prototype, i’m going to have to fix all these bubbles anyway.
  5. I should have built in places to screw this down.
  6. probably should have used deeper registration marks.

Trying to make a mold for a small project I’m working on. I thought it was going to be a simple sculpture to start with. But the size and the fact that I wanted to keep it hollow are making it very challenging. I’ve followed a bunch of different tutorials online about making the mold. That’s not really the hard part. I think it’s very difficult to judge how much silicone you’ll need. Like everything in this it’s really important to plan ahead… which I’m not that good at.
