The goal of this project was to develop a low cost, open source inkjet printer utilizing standard inkjet technology, for personal use. This project was partly in response to the fact that there are no DIY inkjet kits available. There was a kit available from Parallax www.parallax.com/dl/docs/prod/robo/InkjetKitDocs-v1.0.pdf. This kit is no longer made and the book http://www.amazon.com/Inkjet-Applications-Matt-Gilliland/dp/0972015930 that was written to use that kit is now out of print. The prototype design used a carriage assembly constructed from steel rods that were assembled using connectors that can be printed on an FDM machine. The entire carriage system is driven along the x-axis by a belt attached to a stepper motor. The print cartridge, taken from an HP point of sale printer, is driven along the y-axis by another stepper motor belt drive. The electronic controls use an Arduino Mega to run all of the printing systems. The design resulted in a working prototype that fulfills all of the design constraints. The rod frame carriage design is lightweight, easy to assemble and easy to integrate with the other systems. The Arduino used in the electronics has a large library of resources available to perform things like LCD, SD card, and stepper control. Areas where future work should be focused include making molds and casting printable parts to bring down the overall cost, developing host side software, and optimizing the speed.There is a video of this working here: http://www.youtube.com/watch?v=fYeYeTGkvJM There are additional pictures here: http://www.flickr.com/photos/nicholasclewis/sets/72157626730985822/This was a group project involving: Patrick Hannan Jared Knutzen Nicholas C Lewis Joy Markham Print the parts contained in the "Mechanical.zip" file and assemble them as shown in the "DIY Inkjet Printer.pdf". Assemble the electrical components as shown in the "Circuit.zip" & "DIY Inkjet Printer.pdf". Flash your Arduino Mega with the firmware from "Firmware.zip". Use Processing.org to run the script in "Preprocessor.zip" and create a 'print.dat' file. Copy the file onto the SD card and print using the DIY Inkjet Printer.Optionally don't build the x-y carriages and just mount the print head to other robots for mobile printing applications.
