Same. I'm thinking the whole time "you can't recycle film."
I think the problem is that "a 3D print" is a god-awful way to refer to a 3D-printed object.
ETA: Thinking more on it, I just don't think "printing" is a proper way to refer to this process in the first place. Whether we're talking about a motion film, or lithography, the whole idea is that you're forming an image on an existing carrier medium. That's not the case with 3D printing at all.
Analogously, while we call a copy of a film or painting a "print," no one would ever use that word to refer to something like a duplicate statue casting.
