The authors propose "refrigerative stereolithography". In its process, photopolymer resin for a layer is supplied in liquid state and is cooled to become gel state before photopolymerization by laser. After repeating the process for every layer, a fabricated object is obtained by heating, melting and removing only non-photopolymerized resin. Since the object is fabricated in gel resin, support structures are unnecessary and distortion by photopolymerization is reduced. A method of restraining surplus growth caused by over-curing at bottom surface of floating part is also proposed. The effectiveness and possibility of the method are confirmed by fabrication experiments using prototype machine.
