Stereo lithography is an additive manufacturing process that works by focusing an ultraviolet (UV) light source on to a vat of photopolymer resin. With the help of computer aided manufacturing or computer aided design software (CAM/CAD), the UV laser is used to draw a pre-programmed design or shape on to the surface of the photopolymer vat. This process is repeated for each layer of the design until the 3D object is complete. The advantages of stereo lithography is its speed and high accuracy, any of plastic extrusion methods cannot match with the good results of SLA, the stability characteristics of accuracy can be 0.025 mm, almost the best printing quality in the 3D printing industry.
Our expertise of this versatile prototyping technology is extensive. We run various stereolithography machines to produce high quality, low-cost prototypes, our printer that cures layers at ultra-high resolutions anywhere on the platform — even for large parts — and at build speeds much faster than conventional DLP or SLA /laser printers.
