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 therapid 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.
