It looks 3d-printed (edit: confirmed- there's footage of it being 3d printed on the FAQ page). I'd expect a process with a better finish for the final product, but who knows with products like this that are in beta.
Found this sort of funny too, from the FAQ:
> Is this production ready?
> No. The Roc Camera is currently in beta and we suggest you do not use it for anything important at the moment. We're open to feedback and suggestions. Please reach out to us at support@roc.camera.
