If it can be seen and touched then a product can come to life.

Good prototypes can help ensure the suitability of a design and aid physical tests prior to production.

Prototype tooling for diecasting, plastic moulding and presswork

Stereolithography (SLA) prototypes are constructed from a liquid photopolymer that is selectively cured using an ultraviolet laser. The process begins with a 3D CAD file which is mathematically sliced into 2D cross sections. With the build platform positioned just below the surface of the photopolymer, a scanning system is used to draw the first cross section on the surface of the photopolymer, which adheres to the platform.

When the layer is complete, the elevator assembly lowers the platform into the vat and the next layer is drawn, with each new layer adhering to the previous one. The process repeats itself until the object is completed. Actual build times can range from under an hour to over a day, depending on the photopolymer, laser power, and the object geometry. Typically, a mechanical blade is used to sweep the surface of the photopolymer to ensure an even layer of resin for the next layer.
