Mold Making and Resin Casting

Making your Molds
There has been quite a lot of recent interest in this subject so I figured I would help out and contribute a step by step article on how to go through the process of mold making and reproducing parts in resin.

First of all, let's go through the materials you will need to get started.
  • Clean mixing bowls - Plastic rubbermaid type works the best
  • Spatulas - The flexible kind that you would frost a cake with
  • Mixing cups ( I use the clear plastic drinking cups you can buy at a discount store or supermarket. They come in different sizes and usually have lines molded into the sides of them which makes 1/1 mixing easier)
  • Wooden stir sticks
  • Rubbing alcohol
  • Vaseline (petroleum jelly)
  • Different sized small paint brushes (cheap ones, not your Winsor and Newtons!)
  • Some clean rags - for wiping spills and your hands!
  • Sharp Hobby Knife
  • Plasticine clay (Any non sulfurous clay such as Kleen Klay)


There are other materials that will be discussed as we go along, so you may want to make note of them

Good informative article, very interesting. I've often considered making my own castings but have been deterred by the cost and lack of advice- at least one of those hurdles has now been addressed!

Informative article, thanks, now maybe I can get rid of those lousy rubber/vinyl tires...... :-) :-) :-) :-)

Yep, that is what I do also. It's in the article! Thanks Again guys for the compliments. LogansDad, I also use the 10:1 ratio RTV as it is more economical but much harder to use especially for someone just starting out. I used the 1:1 ratio RTV for the artivle for simplicities sake.

Great article, Steve. I recently made my first attempts at molds and casting, and it seems like fun. Your info will help a lot. Thanks for all your hard work!

I was trying to use the micro - mark info but it wasn't as awsome as yours. Now I might be able to do some stuff without ruining it., or waste money to just buy one part from a figure set. Thanks for the info. Happy Modeling
