3D printing service bureaus are not selling the novelty of 3D printing (which is more than 30 years old). They are selling 3D printing's ability to accomplish things that cannot be accomplished via other manufacturing methods. Frequently, it's just rapid prototyping, but sometimes it is also superior cost-effectiveness for short production runs or the inability to produce an object any other way.

All technology is eventually replaced by better technology, but that can take a very long time. Magazines and newspapers are still printed on $1m+ printing presses at service bureaus and the current technology has been around since 1875, with previous printing press technologies dated centuries earlier. I don't foresee a personal 3D printer supplanting something like an Optomec LENS system ($3m+) any time soon, so I believe 3D printing services bureaus could be with us for quite a while – somewhere between 20 and 200 more years.
