About SLA Process


SLA Printer builds accurate parts directly by converting liquid material and composites into solid cross-sections, layer by layer, using an ultraviolet laser.

SLA Description
 

SLA is a laser-based process that works with photopolymer resins, that react with the laser and cure to form a solid in a very precise way
to produce very accurate parts. It is a complex process, but simply put, the photopolymer resin is held in a vat with a movable platform inside. A laser beam is directed in the X-Y axes across the surface of the resin according to the 3D data supplied to the machine , whereby the resin hardens precisely where the laser hits the surface. Once the layer is completed, the platform within the vat drops down by a fraction (in the Z axis) and the subsequent layer is traced out by the laser.This continues until the entire object is completed and the platform can be raised out of the vat for removal.

 

SLA process utilizes a vat of liquid photopolymer resin cured by Ultra Violet (UV) laser to solidify the pattern layer by layer to create a solid 3D model from customer supplied 3D data. The SLA process addresses the widest range of, including the most demanding, rapid manufacturing applications.
