Why is Body Double better than alginate for life casting?
Posted on 7/25/2014
1. Molds made with Body Double have good tear strength and will last a long time and can be used repeatedly to make many copies (castings) of your original model. An alginate mold is destroyed after one use. On the off chance that you can use an alginate mold more than once, you need to do it fast. As an alginate mold begins to dry out, it will shrink and deteriorate quickly.
2. Casting Options; you are limited by what you can cast into an alginate mold – usually plaster. You can cast almost anything into your Body Double mold. You can cast liquid plastics, wax, plaster, low temperature melt metal alloys, concrete and other materials to make your reproduction.
