Have you been following the progress of their Kickstarter? Seems interesting. I wonder if there will be a day in which regular FDM 3d printers will be able to incorporate 3d printed circuit boards all in one piece. I would assume something like this would not be all that difficult to do. You would jut need duel extruders, one for the board and one for the FDM plastics. Technology is progressing at an almost scary pace right now, and that pace just continues to speed up.
