Prototype Process Selection

SLA - Stereolithography

stereolithography employs an ultraviolet laser to cure a thin layer of liquid plastic into a solid. The process operates by taking a thin layer of light-sensitive liquid plastic and passing the beam of a laser over the points where the part is to be solid. Once a pass is complete, another layer of liquid is added to the existing part and the process is repeated until the full part height is achieved.

This method produces prototypes that are extremely accurate and have excellent surface finishes. They are ideal for fit and form testing and visual aids. If you want to accelerate the design process, your completed SLA model, like LOM or FDM models, can be used as a pattern to produce “rapid tooling and castings” that can be used as functional prototypes or actual production parts.
