I just bought a printer and I'm looking for ways to re-use some of the waste: failed parts, support material etc. I have looked at videos about creating your own filament from scrap but that technology doesn't seem to be affordable at the user level yet.

I have seen reference to something called "ABS Slurry" which consists of waste ABS dissolved in Acetone. Has anyone worked with this? Is it moldable? Does it eventually dry out and harden?

Is there a chemical that will do the same with PLA?
