What is BMF projection micro stereolithography (PµSL) 3D Printing?

Projection Micro Stereolithography (PµSL) is a type of 3D printing technology that uses a UV light projector to cure a liquid photopolymer resin into a solid object. The resin is added to a tray, and the UV light projects the desired shape onto the resin. The light cures the resin and solidifies it, layer by layer. The process continues until the entire object has been built. PµSL is known for producing high-quality parts with a high level of detail and accuracy.

Its application spans microelectronics and medical devices such as delicately bespoke surgical stents or microfluidic channels for labs-on-a-chip devices. It can print at 10µm layers to achieve a surface polish of up to 0.4µm Ra on top surfaces and 1.5µm on sidewalls with a diverse  material range including metals, plastics, and ceramics. Users can tailor the material to their application.
