Introduction
This is an inkjet head that is completely makable in a RepRap machine. It was inspired by Johnrpm's Scratchbuilt_Piezo_Printhead.
It has only three reprapped parts. The other parts are standard easily-obtainable items. There is no machining involved in making it - the only tools needed are scissors, a scalpel or razor blade, a hammer, a short piece of 3 mm steel rod to use as a punch, and a glue gun.
It uses a piezoelectric buzzer to drive the ink.
It is experimental, so it's reliability is not yet perfect... But it does work (there's a video below).
I need to do more work on the driver electronics. Then I'll see if I can add heater elements so we can inkjet waxes and wood's metal...
