This weekend I decided to go out to few local garage sales, and I came up with 2 old HP printers. I took apart these printers and I found that most of the side panels are made out of ABS (what Legos are made and one of the most popular 3D printing mediums). Here is picture of the plastic panels:
These pieces are too big, so cutting them up is the next step.
This was purchased through an auction, and has served my recycling process extremely well. When it first arrived I encountered few hurdles. My father really helped a lot with figuring out the electrical side of things. Since the machine is 3 phase, it was not compatible with any electrical outlet in my house. After some googling I found that a static phase converter would work with a 220 volt outlet in my house. After that my father helped me hooked everything up safely. The plastic panels pictured above were turned into granulate after being run through the granulator. The second picture is what filament made from a mix of virgin ABS and the regrind from the plastic panels. I use a ratio of 20% regrind to 80% virgin ABS. Once you start recycling like this filament becomes very cheap (excluding your time spent granulating and extruding).
