Introduction

I'm working on a Stainless Steel piezo that can be heated to jet colored wax. This is to be used as a "Mask" for printed circuit board fabrication.

This process eliminates the need for photo resist and development of a copper clad board. Instead, I use my 3-D printer as a 2-D printer where a board can be placed on my bed and printed directly from Eagle PCB layout software. Then the copper board can be etched and used.

This device can be used for SO many other things besides PC board fabrication. The wax might be able to make 3-D objects but at the very least it can be used to label numbers and letters of your PLA, ABS, or Nylon parts. And an image could be applied to a surface of any 3-D printer device.

Basic Part

My Part 1.jpg

My part consists of 3 layers that are sandwiched together with a 20mm piezo on top. This design also works with a 12mm piezo and would most likely work with a 9mm piezo if the dimensions are adjusted slightly.

Getting it working

Remember that the piezo has a polarity: you want the short mark to eject the droplet and the longer space to allow refill from the tank. You may have to swap the leads to make things work.
