Surface Finish
- After sintering: ≈ 600 μin Ra (15 μm Ra )
- Bead blasting: ≈ 300 μin Ra (7.5 μm Ra )
- Barrel finishing: ≈ 50 μin Ra (1.25 μm Ra )
Post Processing
After printing is complete, the parts are cured in an oven, which enables the parts to be handled. After curing, the parts are sintered and infiltrated with bronze above 1100°C. Cool down can be varied to control the machinability and hardness of the material.
