Rapid Prototyping

High transparency grades will not hide the object inside the mold. Reproducing with artificial resins (PU, Epoxy, PES) will not detriment mold quality.
Pulling the object out of the mold will not damage the mold. All of this is RTV 3040 family.

Reproduction materials used:
→ Epoxies
→ Fast cast epoxies
→ Polyurethane & polyester resins
→ Waxes
