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 |
