Complete Metal 3D Printing Solutions: Post-Processing & CNC

Beyond printing, we handle everything from support removal to surface finishing and precision CNC machining. We turn your raw printed parts into fully functional production components.

  • Support Removal: Carefully removed by experienced technicians. No residual marks on critical surfaces.

  • Surface Finishing: Sandblasting, Polishing, Anodizing, Electroplating.

  • CNC Precision Machining: Tight-tolerance milling and turning for critical dimensions.

Metal 3D Printing Service vs. CNC Machining: When to Choose 3D Printing?

CNC 5-axis machining offers high precision. But our DMLS/SLM metal 3D printing service breaks design limits. Here is how to choose the right process.

  • 1. Complexity (Design Freedom)

    • CNC: Limited by tool access. Cannot machine internal channels.

    • 3D Printing: Unlimited freedom. Ideal for conformal cooling channels, lattice structures, and consolidated assemblies.

    2. Cost Logic

    • CNC: High tooling cost. Complex geometry = higher cost.

    • 3D Printing: No tooling needed. Complexity is free. Cost depends on volume, not geometry.

    3. Efficiency & Lead Time

    • CNC: Requires programming, fixtures, and setup. Takes weeks.

    • 3D Printing: Direct CAD to part. Fast lead times from 3 days.

    4. Tolerance & Surface Finish

    • CNC: Tighter tolerances, smoother surface finish.

    • 3D Printing: Moderate as-built tolerance with layer lines.
