Hands-On With the Voltera V-One PCB Printer (hackaday.com) 37
szczys writes: Eric Evenchick was one of the first backers of the Voltera V-One PCB Printer and just received the 6th device shipped so far. He ran it through its paces and published a review that gives it a positive rating. The hardware uses conductive ink to print traces on FR4 substrate. The board is then flipped upside down and the traces baked on the machine to make them robust. Next the printer dispenses solder paste and the same heating method is used to reflow after components are placed by hand.
