Lifecasting

Lifecasting

Lifecasting is the process of molding and reproducing the human form. The most common material for lifecasting is Alginate. Accu-cast alginates are the industry standard for accurate face, hand, and body casts. In this tutorial we explain the basic hand casting process. Once the negative mold has been removed from the subject, any of our gypsums (plasters) may be poured into the mold.

For "lay-up" casts(much like a brush-on mold), a shell is required to support the alginate mold. In this tutorial we explain the basic use of our Plaster Bandages for making support shells.

 Accu-cast 590 is a great, medium setting alginate for face in hand casts. In this tutorial we make a basic face cast using 590 and plaster bandages. A face cast like this one requires about 1/2 pound of alginate and one 4" roll of plaster bandage material.

Our PlatSil Gels may also be used to mold the human form. In this tutorial we use Gel-10 thickened with TinThix to mold a hand. A Gel-10 mold is more expensive than an alginate impression, however, the finished Gel-10 mold may be used to produce multiple casts. A plaster bandage shell is required to support the Gel-10 rubber mold.
