Inkjet Printer

This repository contains the code, PCB, and CAD of the custom-designed inkjet printer for printing ceramic thin films, which was created as part of the master thesis Development of an Inkjet Printer for Electrolyte Layers of Oxygen Ion Batteries.

See a preview of the control software: https://tuwrraphael.github.io/inkjet-printer/.

An overview image of the implemented inkjet printer.

Details about the printer, challenges and design decisions, its application and evaluation can be found in the thesis.

Repository structure:

• inkjet-printer-app: A web app that controls the printer, is used for planning print jobs, print monitoring & evaluation, calibration and maintenance. Runs in a browser using WebUSB and WebSerial for communicating with the hardware. A deployed version to test an be found here.
• inkjet-printer-zephyr: The Zephyr based firmware of the printhead drive electronics.
• pcbs/Xaar128-Driver: The main PBC design of the printhead drive electronics.
• cad: Various CAD files of attachments added to the printer.
