The PowTReX series enables the efficient reprocessing of build excess metal powder for applications in Metal AM. The integrated vacuum conveyor handles the feeding of the powder - e.g. directly from the build frame of the 3D printer. The recovered powder can be filled into bottles or containers or conveyed by pipe to downstream machines.
Handling the metal powder in a closed system provides a high level of protection for personnel. The PowTReX systems are ATEX certified and therefore also suitable for metal powders with dust-explosive risks.
The PowTReX family includes two series or performance classes: the PowTReX and the PowTReX basic. In addition, we can also offer customized solutions for special requirements.
PowTReX enables powder reprocessing at a high throughput, and is therefore also suitable for 3D printers with large build volumes, as well as for multi-machine arrangements.
PowTReX basic offers the essential functions for the reprocessing of metal powders. The performance is designed for small to medium 3D printers. The prepared powder can be filled, for example, into an EOS bottle, SLM bottle or similar containers from other manufacturers.
PowTReX in a customized design
In the event that your requirements are not covered by any of our standard PowTReX systems, we can also build customized special designs to suit individual requirements.
The metal powder is conveyed into the PowTReX through a hose or pipe by vacuum conveying. There are numerous possible setups:
The length of the conveying pipe can be up to 25 meters and can also accommodate height differences. The high conveying capacity allows on the one hand the buffer hopper in the PowTReX to be filled quickly and at the same time the discharge point is quickly available again for subsequent tasks.
Within the PowTReX, oversized particles, composites and foreign bodies are separated by a sieve. Stimulated by an ultrasonic generator, high throughputs are achieved. In addition, sensors continuously measure the loading of the sieve with powder. The material supply from the buffer hopper is controlled accordingly ensuring the sieve screen is always optimally loaded with powder. The particles and other foreign bodies separated during sieving are collected in a bin.
