The recent consolidation in the #3DPrinting market has been interesting from its lofty promise back around 2015 or so.
I can recall many pilot programs at many manufacturers that I saw personally.
#Manufacturing is a tough nut (perhaps, the toughest nut) to crack in terms of displacing entrenched, proven processes like #CNC machining and casting.
Newer entrants like #DesktopMetal and #Markforged, complete with some very innovative metal printing technologies, never really did take off near as I can tell from my view of industry.
