Abstract: Systems and methods are disclosed for on-demand manufacturing. According to certain embodiments, the on-demand manufacturing system has a digital parts library and a pop-up factory. The digital parts library is configured to store manufacturing information of at least one part, and to receive an order for manufacturing one of the at least one part. The pop-up factory is housed in a mobile unit. The pop-up factory has a network connection, a 3D printer, and post-production equipment. The network connection is configured to receive the order and manufacturing information from the digital parts library over a network. The 3D printer is configured to print the part based on the manufacturing information. The post-production equipment is configured to finish the 3D-printed part based on the manufacturing information.
