Even without recycling. Imagine these which are already happening:
1. A women gets her jawbone printed and transplanted successfully;and
2. A guy prints a working gun and another embarks on a project to enable people to easily and cheaply print guns (last I heard the 3D printer he was to lease to run the project was withdrawn by the owner citing his lack of permit to manufacture guns).
And then there are scientists talking of printing body organs!
