Volkmann PowTrex Eliminates Metal Powder Waste
RAPID 2020: Volkmann’s PowTrex recovery station provides contained metal powder transfer, recovery of unused material, screening for oversize agglomerates and return-to-use of the material.

Volkmann PowTrex systems not only eliminate needless waste of costly metal powders but also to avoid risks when handling these potentially explosive or toxic materials during additive manufacture, thereby keeping the manufacturing operation running at peak efficiency.
Volkmann’s PowTrex recovery station provides contained metal powder transfer, recovery of unused material, screening for oversize agglomerates and return-to-use of the material. The system transfers high bulk density powders with high throughput rates, capable of handling powdered metals such as stainless steel, aluminum alloys, titanium, chromium-nickel alloys, copper and others. PowTrex operates at throughputs of above 1100 lbs/hr. for stainless steel on a 63µ screen, and above 660 lbs/hr for aluminum powder.
Two options are available, inert or non-inert, (both with high levels of containment) to meet requirements due to potential environmental issues, operator safety, and oxidation level requirements. The inert PowTReXi system is designed in a closed loop configuration so inert gas is both contained and reused, avoiding the additional cost of large volumes of inert gas. It offers a high performance, fully inert process with two O2 sensors, an active container and system purging along with a special configuration gas-tight electric pump to maintain system temperature and containment.
Investing in 3D printing for rapid tooling brought product development time from months down to weeks for this moldmaker.
Disrupted supply chains are just one more effect of the coronavirus pandemic. These 3D printing service providers are ready to help fill production gaps with parts, tooling and prototypes.
Arizona Home Floors considered buying a mold to produce a plastic version of its DustRam product. But when a prototype proved durable enough to withstand working conditions, the production strategy shifted to 3D printing.
