One of the major drawbacks of 3D printing is the price of print stock. In some of the more expensive systems, 3D-print material can cost as much as $450/kg for photopolymers. Even the price of cheaper filament material can come in at $48/kg.
To make the world of 3D printing a little more affordable, a company named Filabot has created a machine that will “grind down various types of plastics to make spools of plastic filament for 3D printers.”
Kerry Stevenson, aka "General Fabb" has written over 8,000 stories on 3D printing at Fabbaloo since he launched the venture in 2007, with an intention to promote and grow the incredible technology of 3D printing across the world. So far, it seems to be working!
