Stereolithography (SLA) 3D Printing Technology
At a Glance
About the Process
Stereolithography, or SLA, is a 3D printing technology known for achieving highly detailed and functionally accurate parts. The technology utilizes a mirror that is programmed to direct an ultraviolet laser to draw and cure a part’s cross-section onto a vat of photopolymer resin. After each layer, the build platform lowers and a recouter blade wipes over a new layer of material on the top of the tank.
Once the part is complete, it is removed from the build chamber, cleaned of support and excess resin (typically using isopropyl alcohol), and then placed in a UV oven for further curing. This ensures the part reaches its optimal physical properties.
Our global manufacturing ecosystem includes manufacturing partners with 3D Systems professional grade ProJet printers that are capable of very precise and highly detailed printing. The main sections of the machine include the build chamber and the material chamber below. The build bed can be removed to carefully detach the printed part and clean it of any remaining support material.

Note that any surface in contact with support will have small nubs in the final product as a result of support removal. To optimize the overall surface smoothness of the part, avoid extra overhangs, steep slopes, or large flat planes that may add more structural support.
