We’ve all seen printers use ink, and if you’ve been to a Maker Faire you may have been lucky enough to see a machine printing with chocolate or pancake batter. RIT Assistant Professor Ted Kinsman decided that he wanted to print with coffee. “For many years I have thought about building a machine that could paint for me,” he says. “Since I always have leftover coffee, I thought it would be a fun medium to play with.” Using an Arduino and an x-y plotter, he’s been able to do just that.
