I've done some full color resin printing on Mimaki printers, and it's really incredible.
Hey Gears is about to launch their G1 on kickstarter, with the top of the line model supporting full 8 color (6 color plus support and transparent with an Epson print head) UV printing. It will have a print area of 420x330 (A3 size) by 150mm height, and will cost about $5K.
