A Comprehensive Guide to SLS 3D Printing in China
3D printing has revolutionized manufacturing, offering innovative solutions for rapid prototyping and production. Among the various 3D printing technologies, Selective Laser Sintering (SLS) stands out for its ability to create complex geometries without the need for support structures. This guide explores SLS 3D printing, its technical features, and its applications in China, highlighting key players in the industry.
What is SLS 3D Printing?
Selective Laser Sintering (SLS) is a powder bed fusion technology that uses a high-powered laser to fuse powdered materials into solid structures. The process begins with a thin layer of powder spread across a build platform. The laser selectively fuses the powder according to the 3D model, layer by layer, until the final part is complete. This method is particularly advantageous for producing durable and functional prototypes.
