I started this project because I wanted to build a binder jetting 3D printer like https://hackaday.io/project/86954-oasis-3dp, but with a selfbuild printhead. So I started building my printhead based on https://reprap.org/forum/read.php?153,52959,page=1 and https://reprap.org/wiki/Reprappable-inkjet.
First I build the Reprapple-Inkjet design, but with an acrylic block for the "fluid chamber" instead of a 3D printed part.
Later I changed from the transformer to a H-bridge and added the upper connection for flushing the air out.
After that I tryied to build a pressure control system based on load cells to keep the pressure stable when the fluid level in the tank gets lower, but I figured out that it was not precise enought to work.
