This is something that has been floating around for quite some time now and I thought since it seems a few of us are getting into DIY projects I thought I would post it up.

Basically it is an inkjet printer but instead it uses liquid materials like plastic and builds 3D objects drop by drop. You can make anything you want basically if you use the right materials you could fab circuit boards, just watch the video. I want one so bad I can taste it, lol.
