Need to grind your plastic down for an exruder?

[RobH2]

There are a few filament extruders making the scene and I'd guess that soon we will all own one. The problem is how do you get your scrap plastic down to the size of pellets? Most of the homebrew extruders I've seen don't include a good way to reduce that box of plastic to small pieces.

Here is one way, Liquid Nitrogen and a blender. It's as brilliant as it is radical. Only problem, where do you get it, how do you handle it safely and how much does it cost. There's always a hitch...?

Use Liquid Nitrogen to reduce your plastic.
