Just wait, SOLID 3D image printers are on the horizon.
Imagine if any small convenience item can just be printed up rather than buying. (think replicators on star trek)
Suddenly all those “little things” that no longer need be bought because they can be manufactured in the house.

Plastic printer that offers a 3D glimpse of the future
It is not the song that is being affected, here. It is the distribution model. (BTW Virgin Records is shutting down more stores)
Solid 3D printers have been available since the early 90's. They have just been well out of the range of affordable for the average person. The earliest ones employed a 3D solid modeling program driving a laser cured epoxy medium. The "printing" occurred at a thin slice boundary between the solid object and the liquid feedstock. It has been used for some time to generate prototype models and/or casting positives. The "printed" object isn't particularly strong or stable. Use it as a step enroute to an investment casting as used by Ruger and you have a great path from the computer to the factory floor.
