The present invention relates to a 3D design file protection system that enables 3D printing material to be printed only from designated devices in order to prevent unauthorized copying, etc. of 3D design files, and with respect to a system for protecting design files for 3D printer printing, comprises: an interface unit providing an interface for inputting user information, registering and encrypting a 3D design file, and requesting the transmission of a design file; a first transmitting/receiving unit receiving a 3D design file registered through the interface unit; an identification information input unit receiving the input of user information through the interface unit; a file encryption unit encrypting the 3D design file by using user information input through the identification information input unit so as to generate an encrypted design file; a storage unit storing the 3D design file received through the first transmitting/receiving unit, user information input through the identification information input unit, and the encrypted design file generated by the file encryption unit; and a controller carrying out controlling to transmit the encrypted design file, encrypted by means of the user information corresponding to the transmission request, through the first transmitting/receiving unit, in response to the transmission request input for the encrypted design file received from the interface unit, wherein the user information includes device information on the 3D printer. |
