[Nicholas C Lewis, Patrick Hannan, Jared Knutzen, and Joy Markham], students from the University of Washington, have recently taken the wraps off a project which they have been collaborating on, a DIY inkjet printer. The group set out to construct a low cost, open source inkjet printer for personal use that utilizes standard inkjet technology. Their working prototype, pictured above, satisfies all of those requirements, making it an ideal device for the at-home hobbyist.
The printer was constructed from easy to obtain components such as steel rods and stepper motors, along with other parts that can be printed using a RepRap or similar machine. An Arduino Mega manages the steppers and repurposed print head, recreating whatever Processing-generated image it has been given.
The printer is quite a hit so far, and people are already talking about adapting the design to print on spherical objects (think EggBot), to create direct etch resist PCBs, and more. We think it would make a great direct to garment printer with just a few small tweaks.
