Aspiration, screening und recovery of metal powder for AM

3D printer with connected PowTReX and optional return-to-use transport of sieved metal powder back to the 3D printer.

Aim of the PowTReX to recover usable expensive metal powder after the printing process and to discharge material that is no longer usable for the printing process. The sieved powder returned to the production cycle, increasing efficiency.

The system provides reliable and safe operation with all common metal powders for additive manufacturing, including stainless steel, aluminum, titanium and others.

The system has a high material throughput of up to 500 kg / h for stainless steel and up to 300 kg / h for aluminum powder in a very small footprint.

Optionally the sieved powder can be recover automatically back into the 3D printing process by vacuum conveyor technology.

The explosion-proof system with its integrated HEPA filter ensures a safe and clean working atmosphere.

Also available as closed-loop / inert system.
The system works with both, normal atmospheric air and inert gas. If inert gas delivery is required or desired for product protection, the PowTReXi system will run in a “closed loop” mode. The inert gas is kept in the system cycle and will be reused, not consumed. Additional costs for large amounts of inert gas are thus avoided.
