Selective Laser Sintering (SLS) 3D Printing
Description
SLS is a cutting-edge 3D printing technique that uses polymer powders. In this process, a thin layer of powdered material is evenly spread across the build plate. A laser beam then selectively melts the powder according to the design, layer by layer. As each layer is completed, the build plate descends, and a new layer of powder is applied, with the process repeating until the part is fully formed. The surrounding powder acts as a natural support structure, eliminating the need for additional supports. This method is particularly well-suited for producing intricate, high-strength components with exceptional durability.
