Our painted finish improves the appearance of your 3D-printed plastic parts by providing a smooth, uniform, and professional cosmetic covering.
Painting is offered for both FDM and Resin parts, which helps to hide small surface irregularities, enhance overall uniformity, and provide a refined final appearance suited for display, evaluation, or functioning prototypes.

Design Considerations for Painting
1. Surface Accessibility
Large flat surfaces, exposed outer faces, and open curves paint cleanly.
Very tight interiors or partially enclosed features may show reduced coverage or minor shadowing.
2. Complex Geometries
- Deep grooves, small pockets, and internal corners may not receive even coverage.
Round edges and flat surfaces deliver the most uniform finish.
3. Dimensional Impact
- Painting adds a thin coating layer (~0.1–0.2 mm).
Critical tolerances or sliding features should be masked.
4. Material Differences
- FDM parts naturally absorb paint differently due to visible layer patterns.
Resin parts achieve a more consistent painted finish because of their inherently smooth surface.
5. Masking Requests
If certain regions must remain unpainted (snap fits, functional zones), mark them in your drawing so masking can be applied.
Painting Process
Painting gives 3D-printed parts a smoother and more finished look. It evens out surfaces, reduces visible marks, and gives both FDM and Resin parts a clean, consistent appearance.
How We Paint 3D-Printed Parts at Mech Power
- Inspect and clean the printed part after support removal
- Perform sanding (wet/dry for FDM, micro-sanding for resin) to minimize imperfections
- Apply primer coating for improved adhesion and uniform color
- Spray matte or glossy paint in controlled applications
- Allow curing for optimal finish strength and surface stability
- Final inspection for surface consistency, color uniformity, and finish quality.
This method delivers FDM and Resin parts that look polished, uniform, and ready for product displays, client demonstrations, or final visual evaluation.
FAQS
Frequently Asked Questions
Yes, always. It helps the paint look clean and consistent.
FDM supports many colors. Resin supports black only.
Matte is subtle and low-shine. Glossy is reflective and polished.
It hides minor lines, but sanding first gives the best result.
Only a little. If you have tight-fit areas, we’ll mask them.
