Selective Laser Melting (SLM) is an advanced 3D printing technology that uses a high-powered laser to fuse fine metal powders into solid parts. The process involves layering the powder and selectively melting it according to a digital design, allowing for complex geometries and lightweight structures. SLM is widely used in industries such as aerospace, automotive, and medical for producing components that require high strength and precision. This method enables rapid prototyping and reduces material waste, making it an efficient choice for manufacturing customized parts and intricate designs.
