Our team loves stories that merge sustainability with 3d printing, and a new tool which uses old plastic bottles and bags to create objects is an excellent example.
Renegade, a new 3d printer pen which has already topped it's fundraising goal, is capable of using regular filament like the 3Doodler pen, however it can also recycle used plastic bottles and plastic bags from the grocery store, by extruding the plastic. The old plastic is turned into a useable form for the Renegade pen using a device known as the ChupaCut (see video below).
The team behind this new 3d printer pen has found a way to recover more of the 1 trillion plastic bottles and bags used around the world each year, of which we're only able to recover 5%.
"Renegade uses a robust and powerful extruder that includes a screw-feeder mechanism and heating system. These combine to transport, destruct, and melt the plastic tape produced by the ChupaCut plastic bottle shredder or even standard filaments," the company writes on its kickstarter page. "The rotating screw forces the heated plastic to move forward evenly and extrudes it from the nozzle. The molten plastic then cools down rapidly into a solid and stable spatial structure."
A basic Renegade Pen will run you approximately $80, and if you want the ChupaCut to go along with it, that's an extra $25.
