3D Printer and Inventory Control and Distribution System for 3D Designs

A computer system is configured for digital rights management for distributing and tracking downloadable proprietary source code defining a 3-D object and being usable to print the object on a 3D printer and protect the 3D object data from unauthorized printing. The computer system stores an inventory of proprietary source code corresponding to designs of a plurality of 3D objects, and enables a user to see the inventory of designs of the plurality of 3D objects in an online store, and permits the user to securely purchase use of the source code of a desired 3D object viewed therein. The computer system sends the proprietary source code defining the desired 3D object to a 3D printer, and controls printing of the desired 3D object made by the 3D printer to prevent further use of the source code when the purchased use in completed, using one of three different typologies.
