Thank you for a fine informative video.

Every time Jack Beuth mentions the metal powder stock in all the videos I've seen so far there's a smile and/or a strong statement about it's being manufactured and supplied by the printer companies. I don't believe he approves of the monopoly on powder supply. How much of Arcam's profits are derived from powder sales? What effect will Alcoa's powder manufacturing have on Arcam's powder market share?

He mentions that the void problem will be solved so post build processing needed for eliminating voids will no longer be necessary (HIP). That's good but to take care of the problem they have to detect voids during the build and fill the void, and, there's a small percentage of hollow metal spheres in at least Arcam's powder that have to be eliminated. Those hollow spheres lead to one type of void. I'm very interested in whether or not Alcoa has solved the hollow sphere problem in powder production.

With recent Beuth-Alcoa activity I'm not so sure they haven't solved the hollow sphere problem.

The other video where Beuth mentions the powder interests in in post # 4187.
