The PowTReX is a vacuum, transfer, sieving and recovery system for metal powders, developed for use in the additive manufacturing (AM) industry. It is used to transport metal powder from, for example, 3D printers and unpacking stations with a high and constant suction power. The extracted powder is sieved and the material with the appropriate particle size can be automatically returned to the process.
The system has a small footprint of less than 1 m² and offers a high and stable material throughput. The PowTReX is a reliable, safe and easy to use system which utilises a HEPA filter for protecting against harmful substances. Installation in an EX zone 22 is also possible because it is an ATEX-approved system with type-tested components. It is operated using a touch display and one-button operation.

With this system, classification of all common types of metal powder and their alloys for additive manufacturing is possible (including stainless steel, aluminum, titanium, amongst others). Operation under fully inert conditions with a residual oxygen content of <1% is also possible, as is a complete closed loop solution for the inert gas recirculation.
