Body Double(TM)
Body Double(TM) Advantages: Body Double (TM) allows
you to make a mold directly from a live model. You are therefore capturing
"first generation" detail from the model vs. second generation detail with
the alginate mold process - assuming you want more than one casting.
Not having to make a second production mold from a one-off casting taken
from an alginate mold saves valuable time, materials, and money. And being
a platinum silicone, you can cast many materials into a Body Double(TM) mold
including resins, plasters, low-temperature melt metal alloys etc. - over
and over again. Body Double(TM) molds will last for years in your mold
library with no shrinkage.
Body Double(TM) Release Cream: Alginates will
release body hair easily by virtue of having no tear strength. Being a
high-tear strength silicone, Body Double(TM) will not stick to skin, but will
encapsulate and mechanically stick to body hair. Many "volunteers" from
the Smooth-On sales team found out the hard way by losing swatches of hair
from the forearm, that release preparation of some sort is required. In
our search for a release agent, we tried a variety of preparations,
including skin creams, hair conditioners, petroleum jelly, and
combinations of these products. We came up with a skin conditioning blend
that releases Body Double(TM) rubber better than any preparation or
combination we tried. This cream will not inhibit the rubber.

Perfect detail reproduction - and unlike alginate, this mold will
last for many castings. The total time, start to finish for making
the mold, support shell and finished cold-cast bronze casting was
about 1 hour. |
