This is my attempt to build an open source inkjet printer by myself. I started this project because I wanted to build a binder jetting 3D printer but could not find any open source inkjet printer designs for this. So I started trying to build one.
The first toolhead design is a piezo printhead inspired by https://reprap.org/forum/read.php?153,52959,page=1 and https://reprap.org/wiki/Reprappable-inkjet.
It's controlled via a L298N H-Bridge and PWM from the 3D printer. The printhead runs on 36V DC and the puls is created by an Arduino Uno.
The next design will increase the printing speed by the use of multiple printheads.
