Selective Laser Sintering (SLS) is a 3D printing technology that uses a laser to selectively fuse powdered materials, layer by layer, to create a 3D object. The process begins with a 3D model designed in CAD software, which is then sliced into layers by the printer's software.
The powdered material is stored in a bed, and a laser scans the surface of the material, selectively fusing it according to the design's specifications. The fused layer adheres to the previous layer, and the process repeats, building the object layer by layer until it is complete.
SLS can use a variety of materials, including plastics, metals, and ceramics, making it a versatile 3D printing technology. It is known for its ability to create complex geometries and functional parts, including parts with movable hinges or interlocking pieces.
However, SLS printing can be slower than other 3D printing technologies, and the powdered material can be expensive and require special handling to prevent contamination or degradation.
