SLS 3D printing uses thermal energy from a laser to bind cross-sections of polymer powder one layer at a time. Once the entire cross-section is scanned, the build platform moves down one layer and the process repeats. The result is a bin filled with parts surrounded by unsintered powder. When printing is complete, the parts are removed and the unsintered powder is recycled and reused in the machine for future builds. Support structures are not required for overhangs and undercuts as the powder from each previous layer acts as the support.
Selective Laser Sintering produces strong end-use parts and functional prototypes with outstanding resolution, surface finish, and edge definition. Post-processing steps can then be employed to improve visual appearance, such as dyeing or polishing.
