What is Stereolithography (SL)?
Stereolithography (SL) is a laser-based 3D printing process that uses a liquid photopolymer resin which is selectively hardened by an Ultra Violet (UV) laser beam. The imaging process is done layer by layer as the platform lowers until the printing is complete. The object is then rinsed and further cured in a UV oven.
SL is a widely used rapid prototyping process that can handle large prototypes and odd shapes. It is an ideal solution for the inexpensive and quick fabrication of 3D models for use in a wide range of applications. Objects made with an SL Apparatus (SLA) are accurate, durable, and have smooth surfaces.
