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
