Using an inkjet to print water based glue?

I am thinking about playing with an inkjet printer to print 3d sand casting molds. To save time, I won't be too specific in my design, but I basically want to modify an inkjet to print a water based glue onto layers of sand to create sand casting molds like the 3d printer in this video:

Someone also made a crude version of what I want in this video:

My theory is that if an inkjet printer heats up the water in the ink creating a bubble of steam to push the rest of the ink out, wouldn't the same concept apply to a water based glue if you put that in the inkjet?
So here are my questions:
1) Would it be possible to put water based glue in an inkjet and have it print it?
2) Are water based glues are ok to use in sand casting molds?
Tell me what you think and thanks for your input.

1. Don't know - why don't you try it and let us know?

Now, now...what if that's what everyone said on your iPod topic? :-P
Because I don't know how to write apps, but I'm willing to bet the author here is able to have a go at hacking a spare printer.

Not many people have an unneeded spare iPod lying around (yet).

Believe it or not, I don't have an extra printer laying around, I'll need to go find one
: ). And the reason I asked was to find out if anyone has tried something similar and failed before I go wasting time on the idea. But since nobody brought up any red flags, I just might try experimenting with it... after I find a printer.
depending on the printer, you just need a cartridge, not a whole printer. most inkjet printers have the printheads built into the cartridge (that's why they're expensive...well...that's why they tell you they're expensive anyway). you "shouldn't" ruin a printer by just taking a black cartridge, emptying it, cleaning it, filling it with glue, and seeing what happens.
You might want to research more on the print head technology since the ink is thinned out to some consistency as not to have the ink pigment particles clog up the microscopic sized droplet hole. You would have to figure out what kind of glue would work. And the formulation of water based glues does not cure instantly when it hits the molding sand. You would have a slumpy pile of deforming wet sand if you do not have something that cures the glue on contact - heat lamps or halogen flash?
