Summary of Equipment
The rePowder platform is offered as a method of producing highly spherical nanopowders with a narrow particle-size distribution. The feedstock is either arc-melted or induction-melted over a cold crucible. 40kHz vibrations are applied to the melt through a transducer, freeing spherical particles which are cooled into powder via the argon atmosphere. After filtration, the powder is collected in a sealed canister for subsequent analysis or processing.
The powder produced is ideal for laser powder-bed fusion AM techniques. The system can be configured for 70kHz to yield powders that are suitable for binder-jetting, or LPBF with very narrow particle-size distribution. While the system was designed for 3D-print style processes, users may wish to use this system for its ability to recycle scrap material into powder, or as a precursor for other processes such as SPS.
In Research
A comparison of the microstructure-dependent corrosion of dual-structured Mg-Li alloys fabricated by powder consolidation methods: Laser powder bed fusion vs pulse plasma sintering
This research group examined the structural properties of a magnesium lightweight alloy produced by powder bed fusion and pulse plasma sintering. This material is favorable for its mechanical properties and corrosion resistance, but has poor ductility and formability, which effectively restricts its manufacture to additive manufacturing techniques. The powder for these processes was produced by re-powdering cast and extruded mg alloy pieces on the Amazemet platform. The powder was suitable for each powder consolidation method used. The corrosion resistance of powder bed-fused vs pulse plasma sintered Mg-Li alloys was evaluated, and traced to the differences in microstructure between each product.
