There are a large variety of secondary services that can and in some cases should be performed depending on the alloy being printed.
For Surfaces:
- Finish CNC (3- and 5-axis milling)
- Turning
- Wire EDM
- Polishing
- Plating
- Passivation
- Anodizing
- Tapping and Reaming
- Hardware Installation
- Powder Coating
- Assembly
For Heat Treatments:
- Hot Isostatic Pressing (HIP)
- Solution Annealing
- Aging
- Stress Relieving
- NADCAP
For Powder Analysis:
- Chemistry
- Particle Size Analysis
- Traceability
For Testing:
- Tensile Bar Pull
- Rockwell Hardness
- X-Ray
- Stress Testing

Technical Info
Tolerances for as-printed parts are + 0.010” throughout
Wall thickness should be designed at 0.030” (supported)
Wall thickness should be designed at 0.039” (unsupported)
Minimum feature size 0.015” but 0.020” is optimal
Minimum hole size is 0.030” and in some cases can be as thin as 0.022”
Lettering should be designed at 0.19” tall or deep with a minimum font size of 14
Fillets are valuable in that they reduce stress which tends to occur with DMLS metal 3D printing
Improved tolerances can be achieved by adding approximately 0.045” worth of stock to all areas where finish CNC is desired. Finish CNC can achieve improved tolerances of + 0.0005”
