Doesn't that create a disruptive influence for any company creating smaller products and devices? Not suggesting that it's a catastrophe...but where does this road eventually lead?
But more seriously, seeing all this happen gives a very clear glimpse of the future. Stores full of merchandise will be slowly replaced by online catalogues where you can preview your object, optionally modify it as you like, and send it off for printing. Items may be eventually printed at home since every family will have a 3D printer just as every family now has a computer, but for short-term future there may be whole companies that will set up printing factories with high-end printers, and they will mail more complicated objects to you.
Think of it this way: a 3D printer is a general purpose tool; it really can't compete with individual tooling optimized to pump out millions of units of a single product. For prototypes and engineering testing, it's awesome (sometimes[1]); for mass production not so much.
[1] I have seen instances where a design engineer had to make a "hybrid" prototype part that was partially done on a 3D printer and partly on a traditional milling machine to make up for deficiencies in the 3D printer output.
To my mind though, this is only 1/2 of the problem. most fiction has focused on nano fabs + nano dissemblers. perfect recycling + perfect fabrication.
Of course at the beginning the products will be sold assembled from shops with 3D machines for rent.
