selective laser sintering

Selective laser sintering (SLS) is a 3D printing process that creates three-dimensional objects by fusing powdered material, typically plastic or metal, with a laser. This method involves precisely heating and melting the powder particles at specific points, causing them to bind together layer by layer.1

The process begins with a digital design, which is then translated into thin, two-dimensional cross-sections. The 3D printer spreads a layer of powder and uses a laser to selectively sinter the material according to the design for that layer. This is repeated until the entire object is formed.1

Sintering itself is a manufacturing technique where particles are heated below their melting point to weld them together, reducing surface energy and improving material properties. SLS is a form of additive manufacturing, allowing for the creation of complex and customized parts.21
