Since 3D printing is becoming an increasingly big deal, it was only a matter of time before someone starting using 3D printer filament for social good. Founded by MIT environmental engineering student Sidhant Pai, ProtoPrint offers 3D printing services to students and professionals in India.
Through their collaboration with Prune, India cooperative SWaCH, ProtoPrint helps the SWaCH employed waste pickers, who collect plastic bottles and separate recyclable and organic materials. These bottles are cleaned and run through a shredder, then melted down and spooled into filament reels. In this way, ProtoPrint's ethical 3D printer filament bridges technology and grassroots recycling.
The ProtoPrint pilot is in its final stages and the organization is preparing to launch by the end of this summer.
