We’ve seen a great deal of 3d printing lately, with the RepRap as well as Cupcake, both the fused deposition modeling type. We don’t commonly see the Inkjet method. This is a excellent example of one, developed in someones home. instead of laying down layers of molten plastic, he utilizes the inkjet system to deposit glue like substances into layers of plaster. This job is much higher resolution than the other two, as you can see in the video of it making an RC engine situation below. He is currently rebuilding it to be even much better as well as larger.
