For all the automation effort, there's always something that has to be done by hand...

They define success as being a sample with >50% of the target material. I guess that's success, but wow you can't test any actual properties (hardness, electrical conductivity, etc.) with samples like that.
As the reviewers noted, they're only making oxides (no alloys or intermetallics).
