What is SLA rapid prototyping?

SLA(Stereo Lithography Apparatus)  rapid prototyping makes use of ultraviolet laser or ultraviolet lamp to

shine the sheet liquid photopolymer resin and forms any three-dimensional object model with complex

structure.Due to the forming material is liquid photopolymer resin,so the extremely thin forming layer can

be adopted.

Therefore SLA has a higher forming precision than other China rapid prototyping processes and

certain technological advantages in terms of forming fine structure. In practice, SLA can form

sculpture,handicraft and other electronic product design with assembly precision or casting investment

models of especially complex structure and higher accuracy.

Rison Prototype company is the first company to launch the rapid prototyping process.The technology is 

featured by high precision and smooth surface, but the material is brittle, cost is too high when dealing

with complex, higher requirements on the operators.So it is suitable for assembly design process.
