Ok, check out this Discord. I’m the person that was tasked with designing a printing head that can be 3D printed. If anyone reading this wants to chime in, I can return to work too, and some more help and ideas would be appreciated.

Btw, there is no patent currently active on the most common inkjet printing mechanism that I’m aware of. Other people in the Discord seem to agree. Anyway, this will use a different design, and the code I wrote for my ongoing solid state lab project.
