I like the idea of Filabot (and their kickstarter page) a lot. I generally go through a lot of plastic bottles and other materials during the week. While not ABS nor PLA, there is an aspect of being able to grind my existing plastic (matching materials of course) to make filament to print with… or even grinding prints that aren’t going anywhere to make more filament.
I’ve got plenty of motors around with some good torque, but no line heaters. If I could figure out a way to grind plastic pretty reliably into small enough pieces, I think that would help a lot.
I’m going to keep watching Filabot… In the meantime, I’m going to have kids cutting up the plastic and put it into 5 gal buckets to save for later.
