The problem here is that a revolution is coming, at it will be sooner rather than later, and the change will be very hard on the elite Brahmin of "old money" who think themselves our "betters" by right of riches.
There's a great deal of confusion right now between the technology and end products used in RP (Rapid Prototyping) and what is used in actual consumer product manufacturing.
So, many of the materials used in RP are not much more substantial than "hot melt glue." Which is fine, they do not have to be. (The very first prototype for Google Glass was made from clay and bent coat hanger wire and part of a sheet protector sleeve, and was finalized in 45 minutes.)
There are many out there talking about how "complicated" the process is. Except, it's not--the reason it's called "printing" is that a finished file for anything, a coat hanger, kitchen tools, filter wrench, the ^&@$#@ vinyl rivets that hold license plate frames to front bumpers are simply loaded into the printer with suitable feedstock, and the "Print" button is pushed. To the End User, it will be no more complicated than running a reloading press.
Case in point--suppose you wanted to buy an entry-level 3D printer, they are on eBay now, and for $2-3K. The parts on those printers are largely made on other printers.
Materials technology is not sitting still, either. Partially from the fact that the problem is being looked at from a different angle.
Imagine if, instead of filling up a cabinet with tupperware, you simply pull up a storage container web page, and click on the container you need. If there's IP involved, you get dunned for using that intellectual property, same as you would buying a product in a store. But, you'd only pay the royalty, since you are providing the raw material.
Things will change; others will stay the same.
