Selective Laser Melting (SLM) Services

Selective Laser Melting (SLM), also known as Direct Metal Laser Sintering (DMLS), is a metal 3D printing technology that selectively fuses a fine metal powder in aluminium or stainless steel. This 3D printing technology is used to manufacture both prototypes and production parts, especially with very complex features and all-in-one assemblies.

Finishing Options for SLM 3D Printing

Pros & Cons of SLM 3D Printing

Advantages Considerations
Complex Geometries: SLM makes it possible to manufacture parts that cannot be produced with subtractive manufacturing Surface roughness is higher than with CNC machining
Powdered metals used for SLM 3D printing possess strong mechanical properties Higher costs than other manufacturing technologies
Variety of mechanical and electro-chemical post-processing options applicable for final part enhancement Limited volume size
