> The idea of software in a printer preventing you from printing counterfeit currency is ridiculous. ...but it works well enough. It is embedded in certain graphics program and in (computer-driven) printer/copiers for office use. Not sure about printer drivers, but probably just as well. The tech behind it is quite simple, actually: http://en.wikipedia.org/wiki/EURion_constellation http://en.wikipedia.org/wiki/EURion_constellation However, I can't imagine any similar solution working for 3D print. When one tries to copy bank notes, the `EURion constellation' is there, included by the issuer. However, when trying to print third-party designed 3D item, if the designer did not bother with including any protective markings, those simply won't be there.
