Ryan Sparks of Terror Anatomical, LLC specializes in casting accurate, realistic body parts for clients that use them for films, stage productions, Halloween exhibits, medical demonstration models and more. A recent project for Spencer’s Gifts national retail chain called for making several hundred silicone and urethane plastic castings of a Werewolf’s arm display piece. Normally, Ryan would sculpt in clay and make a mold from that for production. Anticipating that this piece will be used for years to come, however, something more archival than clay is required. Ryan found Free Form® Sculpt sculpt-able epoxy putty to be the perfect medium to create and archival master. His process is chronicled below.
