Stereolithography (SLA)

*** NEW "Pick Your Ship Date"^TMfeature recently added. You now have the ability to choose when your stereolithography parts will ship out. This is just another way that Quickparts lives out the mission of making it easier for you to get the custom parts that you need.***

Stereolithography (SLA) is often considered the pioneer of the Rapid Prototyping industry, with the first commercial system introduced in 1988 by 3D Systems. The system consists of an Ultra-Violet Laser, a vat of photo-curable liquid resin, and a controlling system.

A platform is lowered into the resin (via an elevator system), such that the surface of the platform is a layer-thickness below the surface of the resin. The laser beam then traces the boundaries and fills in a two-dimensional cross section of the model, solidifying the resin wherever it touches. Once a layer is complete, the platform descends a layer thickness, resin flows over the first layer, and the next layer is built. This process continues until the model is complete.

Once the model is complete, the platform rises out of the vat and the excess resin is drained. The model is then removed from the platform, washed of excess resin, and then placed in a UV oven for a final curing. The stereolithography model is then finished by smoothing the "stair-steps."
