I guess it was inevitable. I've seen 3D printers a number of times now, including at the NRC offices in Ottawa and at CFB Gagetown here in New Brunswick. As the story indicates, they work by laying down layers of filler material joined with an adhesive or a laser. The electronic circuitry is created using a squirt tube. The printers that copy themselves still need to be assembled and still need computer chips.
