Time running out for 3rd parties?

Is the future of Transformer addons and custom parts in rapid prototyping/self-replicating machines?
There are a few projects going like the RepRap project or MakerBot Industries. Basically these are machines that can create 3d models of almost anything you can create in a CAD/CAM program. They're biggest claim to fame, however, is that they can produce (almost) all the parts needed to create new machines, meaning they're cheaper than current commercial prototyping machines (which run $30,000 and up). Currently, kits for either machine run about $1000, or if you can find someone who has one, the price of materials plus the parts the machine can't make yet (motors and circuit cards). As the technology matures, the price should come down as the machines are able to produce more of their own parts.
What's this mean for us? How would you like to be able to create or download specs for a part, say a custom gun, or a broken arm, and "print" a copy in a few hours, for pennies? No more waiting months for companies like iGear to produce and ship kits, just buy the files and do it yourself.
In due time, you might even be able to buy the spec from HasTak and create whole figures. No more waiting for stores to stock the 'Formers we can't find! 'Course, that's a long way (10-15 years at least) off, but this could be the key to Star Trek-style replicators.
