MPW scores key Westinghouse contract for assessment of powders for nuclear sector, page-12

From 2017

The MPW process does not involve heat at all: they simply grind metal to produce powder mechanically.

They don’t disclose details of how this grinding process actually works, but the results are impressive. They claim 95% yield, which is comparable to 6K’s – however, less energy is used, and thus one could consider MPW’s process sustainable, particularly over plasma-based powder production.

What’s really interesting is that MPW can apparently not only control the size of the particles, but their geometry as well. They have a “software-defined process that can create a wide range of pre-defined part shapes. This includes particle shapes that would be ideal for additive manufacturing.

At the time, they only had 2 metals...now they’re at 16. 8 years later one can only imagine where their concept will be utilised.
