How To Make a Silicone Mold of a 3D Printed Part and Casting a Detailed Resin Training Skeleton


Watch how a medical training model is cast in resin.

The process starts with a highly detailed 3D print, which is coated and smoothed with XTC-3D epoxy.

Then a Smooth-Sil 936 platinum silicone block mold is poured, capturing every detail with virtually no shrinkage.

Lastly, Smooth-Cast 320 urethane resin is cast into the mold, making the perfect replica.

Several pieces can be cast from the same mold, or it can be archived for several decades in a mold library.
