Instead of trying to craft legislation addressing 3d printed guns directly, it might be more effective for governments to target the 3d printing hobby using environmental rhetoric. They could point to and ridicule the number of "Benchy" boats printed over and over again. A hobby that, at least at first glance, seems obsessed with creating useless plastic trinkets, seems vulnerable to social criticism in this age of environmental awareness.

Not really, not in the sense that most people think of it. It can be composted, but certainly not in the backyard pile of vegetable matter most people will imagine when you talk about composting.

Yeah, but it's definitely a step up from petrochemicals, or in firearms uses, glass-filled nylon.
