SLS printing, or Selective Laser Sintering, is a 3D printing technology that uses a laser to fuse powdered materials, typically plastics or metals, into solid objects. The process begins with a thin layer of powder spread across a build platform. A laser then selectively melts the powder according to a digital design, layer by layer, until the final object is complete. This method is known for producing strong and complex geometries that are difficult to achieve with traditional manufacturing techniques. SLS printing is widely used in industries such as aerospace, automotive, and healthcare for prototyping and producing functional parts.
