WHY 3D printing will fail

If all the crap we buy from China could instead be printed here in the United States, I'm all for breaking their rice bowls.

Sorry, Rodger, you're wrong on this, at least partially. There are quite a number of things unsuited for 3D printing, some that will never be suitable, and an increasing number that are.
About 30-35 years ago DARPA issued an opinion, not an RFP but "something to get people thinking" along the lines of better controlling defense logistics. Their idea was shorten some of the supply chain by shipping bits and bytes to remote CNC equipment to manufacture critical components rather than have a complex, heavily bureaucratic (and, hence, very inefficient) logistics system ordering, stocking and shipping replacement parts worldwide. Twenty years ago Nicholas Negroponte of MIT's Media Lab wrote Being Digital supporting the same concept; Negroponte's rallying cry was "ship bits not atoms."
I doubt the AC blower switch for your Fordrolet will ever be 3D'd on demand from behind the auto parts counter - too many different materials required (copper, steel, aluminum and plastic) plus a bit of complex assembly, nor will a replacement jack handle (too cheaply manufactured with Chinese labor), but various bracketry, knobs, and inserts will because that will be the most efficient way to make them available.
I wouldn't sell my UPS and FedEx stock just yet, but if I were in my 20s or 30s I'd start looking at broadening my investments. - 6/1/16, 4:56 AM

Actually the 3-D movies were a huge success. I can remember sitting through four showings of a Charlie Chan movie with Chinese subtitles because the theater was the only place in town with air conditioning. Revenues increased dramatically with the increased turnover.

They were such a huge success (in the 50's) that they disappeared for 50 years.

High volume mass production is not viable for 3D printers. You really think you can supplant injection molding for, say, rubber dog poop, lego blocks, pill bottles, USB connect shells, or any number of other things you can see without your glasses on? The value of 3D printing is in small run batch, high complexity parts not suited to molding. 3D printing commodity parts is a waste of 3D printing. Advantage is that injection molders will become hungrier so minimum run volumes will drop, letting more varieties of rubber dog poop get made cheaper.

Hey, don't forget rubber vomit. If you're gonna have rubber dog poop, ya gotta have rubber vomit.
