This project began with plans to move: we were going to dismantle an existing powder mixing plant, relocate it and re-assemble it at the new location. However, the more the client grappled with this plan, the more it began to evolve. At first they wanted to optimise the plant, then they felt the need to expand it, until finally they decided to simply construct a brand new plant.
Two factors are particularly important when it comes to the cutting-edge technology of 3D printing: it must have great capacities and be highly flexible. The newly developed powder mixing plant combines these two specifications. On the one hand, it achieves a peak production of 3 tonnes per day – under batch and laboratory control in three-shift continuous operation. On the other, its design allows for flexible adaptation to future developments in 3D printing.
The powder mixing plant consists of a metal structure on three levels. It carries a 3-tonne powder mixer with a buffer vessel on top, as well as a sieving machine and dosing system beneath the buffer-mixer unit. During the installation of the mixing line, 300 m of pipelines were also laid.
