"eliminates the need to have them shipped in from various factories" AND just what teleporter brings the materials that are used in the 3D printing process? So instead of rolled steel stamped on site and weled on location, you'll ship hundreds of thousads of tons of petroelum based meltable plastic to the 3D printer.

Anyone crash test this thing? Burn the flameless ethanol that you can't see its on fire? What happens IF it catches fire from an electrical short? Most plastic burns like crazy.

I love the idea of 3D printers. But they are not the cure-all.
