News:Â American college student Tyler McNaney has invented a desktop machine that makes the raw materials for 3D printing by grinding up waste plastic from bottles, wrappers and even Lego bricks.

Mechanical engineering student McNaney came up with the Filabot as a cheap alternative to the spools of filament used by 3D printers. A kilogram of filament from Makerbot, for example, costs around $50.
Any type of recyclable plastic can be turned into filament, from food wrappers and drinks bottles to water pipes and Lego bricks. The machine grinds up the plastic, melts it down and then extrudes it as a material that can be fed into a 3D printer.
As well as waste plastic, the machine also allows users to recycle their unsuccessful or unwanted 3D-printed objects. "It is a one stop shop for all the filament you could ever need," he explains.

Initially launched on crowdfunding website Kickstarter last October, the machine soon overtook its initial target of $10,000, with backers pledging over $30,000 in total.
McNaney now plans to launch a small range of the machines led by the Filabot Reclaimer, a fully enclosed machine that comes fitted with a plastic grinder. Also available will be the basic Filabot Wee, which comes without a grinder and requires self-assembly, and the Filabot Core, which comes fully assembled. A stand-alone grinder will be available separately.
The first batch of Filabots will be sent out to Kickstarter backers before the machine goes into general production, according to McNaney.

Last year Dezeen also spoke to Bre Pettis, head of 3D printer manufacturer Makerbot Industries, who told us that 3D printing would reverse the industrial revolution by placing factories back in people's homes.
