Having tried a few 3D scanners, they typically give very noisy digital reproductions of a particular object, usually one side is missing. Moreover, 3D printers are very limited in terms of the strength and material of objects. Given that most objects of interest to duplication aren't just one solid chunk of a weak material, but usually consist of many parts created during the manufacturing process, this seems like a pretty trivial risk at the moment.
