The as-manufactured surface is just the starting point. Surface finishing transforms functional prototypes into production-quality components. PrintVX offers comprehensive post-processing for both 3D printed and CNC machined parts.
Surface Roughness Guide (Ra)
| Process | As-Built Ra | After Finishing Ra |
|---|---|---|
| SLA (Resin) | 1-8 micrometers | Down to 0.2 micrometers (polished) |
| SLS (Nylon) | 8-15 micrometers | Down to 1.6 micrometers (standard) |
| FDM | 8-25 micrometers | Down to 3.2 micrometers (bead blast) |
| CNC Aluminum | 1.6-3.2 micrometers | Down to 0.1 micrometers (polished) |
Finishing Options at PrintVX
Bead Blasting
Uniform matte finish that hides layer lines. Recommended baseline finish for SLS nylon parts. Adds 1-2 business days, typically 10-20% additional cost.
Polishing and Buffing
Mechanical polishing achieves near-mirror finish on metals and selected resins. Used for jewelry, dental restorations, and premium consumer products.
Anodizing (Aluminum Only)
Type II (standard, 10-25 micrometers) and Type III hardcoat anodizing (25-75 micrometers). Available in black, gold, clear, blue, and red. Adds corrosion resistance and surface hardness.
Electroplating
Chrome, nickel, gold, and zinc plating available. Enhances appearance, adds conductivity, improves wear resistance and corrosion protection.
