A normal 3D printer creates a figure cover after cover but this new printer do it diferent. This combines liquid resines, ultraviolet light and oxygen. The result of this method is to create the figure 100 times faster.
Opinion
It's a great idea that you can create something useful from your pc but it's so expensive. I'll afirm that is not only pay the priner itself, you need the liquid aand the design of the piece. To design it, you need a special program and some knowlege of drawingThe best thing is that you can create a organ or some part of the body for somebody who needs it because it doesn't damage your body and your health.Some printers have create a part of the face of one human. They created a duck leg also. They are very useful but we aren't using it at 100%.
The biggest problem is that some bad person can create arms with it.
