Let our experts advise you on the gas supply modes and mixtures for optimized binder jetting outcomes
The liquid polymer binder is selectively deposited onto the powder bed to join the metal particles at room temperature. Even under these conditions, a controlled process gas atmosphere in the print chamber, using nitrogen for instance, offers major advantages relative to air:
- Safe handling of reactive powders, lowering explosion/ignition risks
- Flexibility to use widely available, less expensive and non-precoated powders
- Avoidance of powder oxidation and cohesiveness from humidity pickup
