Metal powder handling

Alu+Edelstahl Pulver

The correct handling of powders within the additive manufacturing industry

Whether it is metals or plastics there are numerous different powder handling tasks to be solved within the Additive Manufacturing (AM) industry.

However, for various reasons, metal powders represent a greater challenge for powder handling. This involves the powder supply to the 3D printers the recovery of unbound material and its reclassification and recovery (recycling) for reuse.

With the Volkmann PowTReX, the combination of the process steps of vacuum conveying, controlled sieve dosing and ultrasonic screening represents a compact platform to solve these demanding tasks.

Printer and PowTReX

In connection with the correct container and container handling, safe, sealed and – if necessary – inert powder handling can be achieved. This means that not only stainless steel powders, also aluminum and other sensitive metal powders, for example, can be safely handled.

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.

Volkmann are proud to support Materials Solutions, based near Worcester in the UK, who are a Siemens business (since 2016). They utilise additive manufacturing (AM) technologies for the production of parts and tools for the aerospace, automotive and power generation industries worldwide using a variety of metal powders including Ni superalloys, Ferrous alloys and Aluminium alloys.

Materials Solutions has seen an increase in production which has led to the company’s expansion to a larger facility to accommodate additional AM machines to keep up with demand. Their new larger facility now boasts a greater selection of AM machines from various suppliers and in different sizes to increase their manufacturing flexibility. This increase in demand meant that a more efficient, reliable and versatile processes was required to help speed up the powder reclassification procedure between builds.

With some unsatisfactory powder reclassification systems trialled on site Volkmann was contacted back in early 2018 to help with an alternative solution and since then several systems have been supplied. The flexibility of the PowTReX has also enabled Materials Solutions to plan new powder handling and reclassification projects utilising Volkmann equipment which has enabled them to improve their powder reclassification process.

The PowTReX utilises a Volkmann vacuum conveyor to transfer powder from the build chamber to an ultrasonic sieve, via a dosing system which helps prevent overloading of the sieve mesh. With a sieving rate of approximately twice that to other available solutions on the market (using equivalent powder) the PowTreX is a good solution to help speed up the reclassification process.
