Some experts say within a few years hobbyists will have their own 
low-cost machines, many created by other 3D printers. Adrian Bowyer, a 
mechanical engineering lecturer at the University of Bath in England, 
says he is developing a 3D printer that, when connected to a PC, will be 
capable of recreating most of its own parts -- allowing individuals to 
build new 3D printers for little more than the cost of the plastic resin.

3D printers can't replicate semiconductors or metal screws and bolts. 
But products made by printers should be as sturdy as the originals once 
they're assembled. Mr. Boyer predicts this could aid cottage industries 
making jewelry or home furnishings like hooks and vases, or even lead to 
homemade cellphones or digital cameras. He expects a 3D printer that can 
print itself might be ready in a few years. As the self-replicating 
machine spreads, "It will evolve," he says, with the most successful 
changes being widely adopted.

vlt: This sounds promising.  Self-replicating robots, almost.  It 
doesn't seem like too much of a jump to having a second "color" of ink 
that is conductive, leading to coils and motors.  Now fax me a pizza.
