Long before I found my home here at homemadetools.net I made a powder based 3D printer from an old inkjet printer.
I spent a bunch of time testing different powders and liquids in the inkjet cartridge. Back in 2008 there was a thread on the Reprap forum with some of the discussion at the time:

This is a picture of my homemade powder based 3d printer made from an old inkjet printer.
I used a very labor intensive process with this homemade printer. I didn't find a material that I was satisfied with so I never automated the process.
below is a video of my homemade powder based 3D printer in action.
