Abstract: A system allows for the delivery of products through the use of 3D printing technology, enabling a non-technical user to locate, select, and print a product with minimal effort. The system provides a listing of one or more 3D object files for display to a user at a client machine. Once a user selects one or more 3D object files, the system establishes a network connection between the online server and the client 3D printer and then streams the selected 3D object file from the online server to the 3D printer in a format supported by the 3D printer. The system may also process received 3D object files to produce a plurality of formatted 3D object files, each formatted 3D object file converted to a format based on the received set of printing parameters and a set of capabilities for a different 3D printer of a plurality of 3D printers.
