3D printer and inventory control and distribution system for 3D designs

A computer system configured for digital rights management (DRM) to control distribution and track downloadable proprietary source code defining a 3-D object usable to print the 3-D object, and to protect the 3D object data from unauthorized printing, said one computer system comprising:

• a 3D printer;
• said 3D printer configured to deposit successive layers of a material, to form the 3D object;
• one computer, said one computer comprising a memory;
• said one computer configured to store and permit download from an inventory of proprietary source code corresponding to designs of a plurality of 3D objects from a plurality of different designers, said one computer being a single board computer having a unique hardware ID configured to provide an online store environment to permit the plurality of designers to market the respective designs only from said one computer;
• wherein said one computer is configured to interact with an operating system that controls said 3D printer;
• wherein said one computer is configured to display the inventory of designs of the plurality of 3D objects in the online store;
• wherein said one computer is configured to permit a user to browse the designs in the online store, and said one computer is further configured to send a digital file containing the proprietary source code for each of the designs of the plurality of designers to said 3D printer when purchased;
• wherein said one computer is configured to permit the user to securely purchase use of the source code of a desired 3D object in the online store;
• wherein said one computer is configured to send a digital file containing the proprietary source code defining the desired 3D object to said 3D printer after it is paid by the user;
• wherein said one computer is configured to control each print of the desired 3D object made by the 3D printer to prevent further use of the source code when the purchased use is completed;
• wherein said one computer is configured to control the number of prints of the desired 3D object by controlling the proprietary source code defining the desired 3D object;
• wherein said one computer is configured to limit access to the source code to prevent unauthorized use;
• and
• wherein said one computer is configured to store the DRM associated with the purchased code in a database.
