The KeyCast from Keystone is a residue-free combustible 3D printing fluid for the digital production of cast patterns such as frames. The KeyCast is compatible with rapid burnout and gradual temperature rise workflows, and burnout without residue. The Keystone KeyCast is used with chrome, cobalt, gold and silver. The low shrinkage formula controls thermal expansion to achieve pore-free and accurate castings.
