This is good stuff, but the important part is just briefly mentioned: It's the Fadal CNC machine. The other machines scan and build plastic prototypes or occasionally functional parts if plastic is sufficiently tough for the job. But once the plastic prototypes are tested and proven, the Fadal CNC machine then makes them out of metal. I would still like to know what kind of metals the Fadal can machine? And then there's the bet that this technology would continue to get cheaper. This is certainly true of semiconductors and software but will it be true for this, for CNC machines? And lastly, manufacturing "works" on a large scale. You buy raw materials in bulk, manufacture and then sell the now transformed materials in small units. Buy in bulk, sell in small is where the profit is made. But this is very long tail stuff. No one will need a large volume of a special custom widget. Would individuals buy this tech to use over a life time, like a good expensive tool box? Or would a small business buy this and then offer to ship custom parts in a small area where shipping is cheap?
