“Stereolithography (SL) is an industrial 3D printing process used to create concept models, cosmetic – rapid prototypes, and complex parts with intricate geometries in as fast as 1 day. Stereolithography parts can be produced in a wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SL.
The SL machine begins the 3D printing process by drawing the layers of the support structures, followed by the part itself, with an ultraviolet laser aimed onto the surface of a liquid thermoset resin. After a layer is imaged on the resin surface, the build platform shifts down and a recoating bar moves across the platform to apply the next layer of resin. The process is repeated layer by layer until the build is complete.
SL is an excellent choice for rapid prototyping and project designs that require the production of very accurate and finely detailed parts. It’s ideal for producing show-and-tell parts to enable validation of concept ideas and ergonomic testing.”
