Stereolithography

Stereolithography (SLA) is a process that rapidly builds complex geometries in plastic. The machine builds a thin layer of the part in two dimensions utilizing a laser and liquid polymers. This process can produce complex geometries in a matter of hours. Accuracy of the machines is approximately ±0.005 inches (±0.127mm).
