Metal laser sintering

Definition

Metal laser sintering is a 3D printing process that uses a high-powered laser to fuse powdered metal particles together, layer by layer, to create solid metal parts. This technology allows for the production of complex geometries and lightweight structures that are often difficult or impossible to achieve through traditional manufacturing methods. By selectively melting metal powder in a controlled manner, it enables high precision and customization in part design.
