Material-transfer, light cure additive manufacturing system and process

Abstract

An additive manufacturing machine and a method of printing a polymer precursor that exhibits a viscosity in the range of 1,000 centipoise to 2,000,000 centipoise. The additive manufacturing machine includes a light engine and a material feed system configured to feed a polymer precursor exhibiting a viscosity in the range of 1,000 to 200,000,000 centipoise, wherein the material feed system includes a hopper and a roller train, wherein the hopper delivers the polymer precursor to the roller train and the polymer precursor passes through the roller train. The additive manufacturing machine also includes a transfer film configured to carry the polymer precursor and move between the material feed system and the light engine and a support surface positioned at least partially under the light engine and moveable vertically towards and away from the light engine.
