Rapid prototyping resin compositions

摘要

A resin composition suited for rapid prototyping is provided comprising (I) an actinic energy radiation-curable silicone composition, (II) an actinic energy radiation-sensitive polymerization initiator, and (III) an actinic energy radiation absorber. The resin composition experiences little viscosity buildup and maintains fluidity during ling-term storage at elevated temperature, and is effective in rapid prototyping or shaping by stereolithography using any actinic energy radiation.
