Surface Finishing for SLS Parts
Standard Bead Blasting
- Removes loose powder and evens surface texture.
- Default finish for most functional SLS parts.
- No additional finishing required for internal or non-cosmetic components.
Vapor Smoothing
- Reduces surface roughness and seals surface porosity.
- Recommended for visible housings or parts exposed to moisture.
- Not required for internal components or fixtures.
Media Tumbling
- Improves surface uniformity on small or complex parts.
- Used when a smoother touch feel is required.
- Limited impact on tight dimensional features.
Color Dyeing & Coatings
- Adds color and improves surface appearance.
- Used for branded housings or visual prototypes.
- Cosmetic only; does not significantly change mechanical performance.
Specialty Finishes
- Secondary processes such as priming, conductive coatings, or inserts.
- Applied based on application and assembly requirements.
- Feasibility and impact on tolerances are evaluated during quoting.
