Despite their great potential for individualization, 3D-printing processes for polymer parts like SLS (Selective Laser Sintering) and FDM (Fused Deposition Modeling) have the particular disadvantage of a high surface roughness; therefore, surface finishing is often necessary. However, current finishing procedures often have deficits such as low flexibility, long process times or incorporation of abrasives in the component. Therefore, Fraunhofer ILT is developing a non-contact, laser-based polishing process for additively manufactured plastic components.

Laser Sintering 3D Printer, Sintratec, Reaches CrowdFunding Goal, Announces New Materials

Sintratec launched their SLS desktop 3D printer on Indiegogo back in November. Selective laser sintering is completely foreign to desktop 3D printing, and certainly hasn’t been anywhere near affordable. Sintratec, whose printer goes by the same name, changed all this when they offered the world’s first desktop SLS printer for under $4,000.
