I have seen 3D printers and they are the equivalent of a dot matrix b&w printer. The printer is slow in that it is making the part layer by layer and the "ink" has to solidify before the next layer can be added. As such, it is better for prototyping but not for mass production. 3D printing can be good for customizing a design and embedding features that can't be done through current manufacturing processes.
3D printers will take off once the "ink" can consist of multiple materials at the same time, conductive materials combined with transparent materials and insulator material can make more than just a body part.
