Process
Description

SLA builds plastic parts a layer at a time using a laser to cure liquid photopolymer. SLA produces parts with very good dimensional accuracy and surface finish. Vowin employs master model makers to finish your SLA parts accurately to your 3D Data. Choices of materials are available to emulate a variety of thermo plastics.

SLS uses a laser to trace over powder to selectively melt and bond the layers until the part is built. SLS builds parts in durable materials including Nylon and metals. A good choice for proto's that need to be tough.

PolyJet utilizes an inkjet that deposits photopolymer onto a build tray, the layers are cured by UV. PolyJet builds in super thin layers down to just 16 microns (0.0006 inch). Best for small parts with fine details.

FDM extrudes material via a nozzle. The nozzle is mounted to a mechanical stage which can be moved in both horizontal and vertical directions. FDM builds parts in ABS and PC. Surface finish and accuracy is rougher than our other RP processes.

The Rapid Casting process utilizes a master pattern to create a silicone rubber mold. Duplications are then cast in a vacuum chamber. Parts are very durable and cosmetically resemble injection molded parts. Vowin specializes in casting for Low Quantity Production, Over molded Parts, Lens, and Large Parts.
