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.<p>Given that most objects of interest to duplication aren&#x27;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.
