How does Micro Stereolithography work?
Projection Micro Stereolithography (PµSL) uses a highly focused light source to selectively cure photopolymer resin at micro-scale resolution. The process builds each layer with micron-level accuracy, producing intricate, precise features impossible with conventional 3D printing. By repeating this layer-by-layer approach, PµSL creates smooth, highly detailed components suitable for microfluidics, biomedical devices, electronics, and research applications. Its precision, surface finish, and ability to handle complex geometries make it ideal for prototypes and functional micro-scale parts.
