Rapid Prototyping -- Solid Ground Curing

Solid Ground Curing utilizes the general process of hardening of photopolymers by a complete lighting and hardening of the entire suface, using specially prepared masks. A photopolymer liquid in each layer is covered with a photomask and cured for several seconds by a strong ultraviolet lamp. The exposed liquid polymer is then removed and the voids are filled with wax to support the next layer.

Solid Ground Curing was originally developed and sold by Cubital Ltd. of Israel. Their system was very complex and therefore suffered from high initial and operating costs that eventually caused their downfall. The company no longer exists and its intellectual property has been acquired by Objet Geometries, Ltd in Israel.
