MakerBot has revolutionized open source printing by bringing it straight to your home at an affordable cost. But what if you could also supply your own material for 3D printing by using recycled materials? The creators of this blog represent a group of students working to build an attachment for the MakeBot that will allow for just this.

Our RecycleBOT will grind and melt your milk bottles, then extrude them at an appropriate circumference for use with the Makerbot. Let's get to printing.
