Dumb question: what do you describe as "pre-consolidated"
Uwe
Here’s a presentation that shows some of the manufacturing steps. Step 1 is
the creation of powdered constituents using a gas atomization chamber. As I
understand it, the rest of the steps are unnecessary if one is going directly
to an SLM machine.

I’m packaging this information with the additional caveat that I probably don’t
know enough to know what I don’t know, so I don’t know what I’m not telling
you. If someone else knows what I don’t know, I’d appreciate knowing before I
mislead everybody.
