Most people immediately associate the technological magic of 3D printing with replicators from Star Trek (“Earl Grey, hot”), but that’s hardly the only example of this sort of device in sci-fi. My personal favorite comes from the pages of Transmetropolitan, and the twisted mind of Warren Ellis. Ellis’ version had a few problems, but it also had a recycling feature that allowed the machine to break down anything from beer bottles to old boots into new materials to feed itself.
As so often is the case, sci-fi is the prophet of actual science. Although it isn’t quite able to recycle old boots, the Filabot can recycle used plastic to create spools of filament that can be used in 3D printers. Begun as a Kickstarter project by Tyler McNaney, a mechanical engineering student at Vermont Technical College, the Filabot is ready for use, but hasn’t quite hit the mass manufacturing stage.
Filabot has been designed to fit on the desktop, with measurements of 24x2x12 in. You can’t feed whole plastic bottles into the current design, which requires the user to chop the plastic he means to recycle into around 4-in. pieces. These pieces are fed into the machine, which grinds the plastic down into smaller pieces.
While the Filabot does use heat as part of the extrusion process, McNaney says that as long as users follow guidelines provided with the machine, no toxic smoke is produced. The plastic filament produced by the Filabot passes through either the user’s choice of a 3mm or 1.75mm nozzle onto a sizing roller, before being rolled into a spool.
While the Filabot isn’t exactly for sale quite yet, interested individuals who donate $425 or more to McNaney’s Kickstarter account are guaranteed a kit which they may assemble at home. Projects like the Filabot are another stepping stone toward home 3D printers becoming every bit as much the norm as personal computers.
Below you’ll find the original pitch video that outlines the basics of how the Filabot works.
