Closed powder handling loop for Eos metal Am printers
In additive manufacturing, managing and handling metal powders both before and after printing can be complex and labor-intensive. Ensuring the purity and proper distribution of powders is essential to maintaining the quality of printed components.

Automate powder handling and ensure material integrity
The Closed Powder Loop: EOS edition by Volkmann is a fully integrated solution designed specifically for EOS M 290, M 300, and M 400 series 3D printers. This system automates the entire powder handling process, from preparation to post-processing, ensuring efficient and contamination-free operation. It includes modular devices such as the PowTReX, vHub 250, and vLoader 250, which together create a seamless workflow for powder transfer, cleaning, and loading. The system supports up to six 3D printers in a production cell, offering scalability for expanding operations. The PowTReX sieves and purifies metal powders, the vHub 250 acts as a central powder reservoir, and the vLoader 250 ensures continuous, inert-gas-purged powder delivery to the printers. The entire setup helps maintain high throughput and quality in metal additive manufacturing processes. The supplier for this system is EOS.
