The Drip Printer by Ted Kinsman

An x-y axis printer is made by controlling a solenoid liquid valve. Slow and small resolution, but very inexpensive to print with. Here it is printing with blue water color ink, but it mostly prints with coffee. The drip size, and the nozzle distance, and the paper can all be changed. This machine prints with and on anything.
