3D Printers Get Less Expensive and More Functional

Drones may have been flying around the 2015 Consumer Electronics Show (watch 2015 CES on engineeringtv.com) but there were even more 3D printers. Prices are falling and are on par with many high end inkjet printers. They may be a little harder to use but not by much. There are new materials like carbon fibers and cookie dough. There are even handheld devices for the artist that wants to create a 3D model.
