What is
Selective Laser Sintering (SLS)SLS 3D printing service refers to a type of additive manufacturing service that utilizes Selective Laser Sintering (SLS) technology to create intricate three-dimensional objects. Essentially, SLS 3D printing service provides users with the ability to produce complex, geometrically precise, and durable components out of a wide range of powdered materials, without the need for any support structures. It gives the possibility to produce low volume items in a cost-effective manner without investing in expensive moulding tools.
The process goes with a high-power laser or multi-laser to selectively melt the metal powder laid on the platform. This process continues layer by layer, according to the pre-set 3D slice parameters, until all layers are completely fused together. After each layer, the platform sinks accordingly and the scraper recoats the metal powder. The thickness of the new coating is 20 to 100 µm, depending on the accuracy requirements. These steps are repeated until the entire 3D model is completed. Before the post-process the unmelted powders will be removed as well as the support.
