Yes, I can imagine using it. There a couple opensource hardware projects and a few closed source projects in the works that have different levels of promise.
Look at RepRap (I have half the parts for a PRusa now) & Makerbot
I saw those years ago, we had one at my old company....a buddy of mine was a manager for the company in this area, it is located in Burlington MA. the print head basically uses superglue as its ink. it "prints" a layer in a plastic powder, shakes and lowers itself a fraction and prints the next layer building up to its final 3-D print.
it was pretty amazing....it can actually print out fully functional ball bearings that rotate.
trust me....the first time I saw it....fishing lures were the 1st thing that popped into my mind

Someone has made a printer like this that uses a mirror and sand to make glass objects. It's 100% powered by the sun. Posted from my iPhone/Mobile device
