Vac-U-Max’s additive manufacturing metal powder recovery system, AM-MPRS, is capable ofconveying, screening and recovering metal powders including Inconel, stainless steel, Haynes 282 and cobalt chrome. The system increases productivity by extracting metal powders from the printing bed via vacuum, and then sieving the metal powder for future use. According to the company, it can cut metal powder recovery time by 85 percent. The system is designed for ease of use, conveying metal powders in a closed system, eliminating operator exposure to metal dusts and maximizing plant and personnel safety.

The vacuum extracts the metal powder, conveys it to a vacuum receiver and then discharges it into a sieve. The sieve then discharges the metal powder into a pail, drum or IBC in a contained and inert environment. The system is NFPA 484 compliant for handling metal powders and is designed to reduce the risk of cross-contamination. It is said to enable full metal powder recovery and quick dismantle without tools, and its ergonomic low-profile design and mobile frame enable easy rolling with lockable casters.

The system includes pick-up hand tools, and a static-conductive hose with smooth bore. FDA- and USDA-approved PVC hoses are available for non-aerospace applications, and flexible, stainless-steel hoses are available for aerospace applications. The company offers inert gas-purge fittings and an optional gas-purge manifold. Additional features include HEPA filters and canisters, a high-output suspended vibratory sieving machine with US230 mesh, an ultrasonic de-blinding kit and a vacuum receiver.

The Vac-U-Max 316L stainless steel vacuum receiver package offers 36 ft.2 of filter area and a counter-weighted discharge valve. The vacuum generator includes the company’s single Venturi power unit. Compressed air is driven by a vacuum generator with a ½" NPT high pressure air connection. The system requires 35 cfm at 60 psi for operation, with variable orifice assembly for vacuum level adjustment. A NEMA 4, UL-Certified Vac-U-Max control panel offers micro PLC for vacuum conveying functions, a starter for the sieve, a grounding and bonding monitor and face-mount ultrasonic controls.
