【Abstract】 The influence of polymer filler on the shrinkage of photocurable resin used for stereolithography is studied by measuring the viscosity、the specific gravity、the photocuring speed、the linear shrinkage,and the volume shrinkage of the resin containing polymer filler.The resin containing polymer filler is tested on Laser Rapid Prototyping Manufacturing System,and the result indicate that the resin containing polymer filler can reduce the shrinkage of the photocurable resin for stereolithography.更多还原
