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

As-printed（SLM)

Support structures are removed, and the part is media blasted to provide a uniform finish.
Final result:
- Typical surface roughness is between 150-400 µin Ra
Bead blasting

Depowdering of parts with bead blasting. The final parts are slightly grainy in the touch with a satin-like matte appearance.
Notes:
Semi-sintered surface particles remain on the part even after initial depowdering.

Slightly grainy in the touch

Uniform, matte or satin-like appearance
Custom

If a you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually 1-2 business days.

Notes:

Submitting for manual review with a custom request does not guarantee a quote.

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
