Process analysis and application for rapid prototyping based on stereo lithography apparatus

LI Xiao-jing

Abstract

As one of important advanced manufacture technology,stereo lithography apparatus(SLA) has an important practical value.The presents the working principle for rapid prototyping technology based on SLA and summaries its merits and faults.Then the basic constitution of SLA system,such as optical device,vessel system,photosensitive material and control system are discussed,respectively.Taking a non-standard gear as experimental object and the manufacturing process is specified,which final products are manufactured on SCPS350B rapid prototyping machine.Moreover,the application of SLA in production design,mould manufacturing,precision casting and biomedical engineering is discussed.Finally,the future development of SLA is prospected.
