Projet

Projet (not to be confused with Polyjet) was invented by 3D systems.  The Projet process is also inkjet based, but differs from Polyjet in that higher head temperatures enable the jetting of waxes.  The high resolution wax models that it can produce melt perfectly, and are ideal for investment casting jewelry or even functional metal parts.  Most jewelers and professional casting houses will agree that even the best wax filled resins pale in comparison to the castability of 100% wax.
