A geometric model-based evaluation method, system, and apparatus for a key performance indicator in a production procedure are disclosed. The method includes extracting a geometric characteristic and a characteristic attribute thereof from a product model; converting the geometric characteristic into a process characteristic so as to obtain the steps of a process related to a whole production procedure of producing a product, and devices corresponding to the steps of the process; and based on the steps of the process related to the production procedure and the devices corresponding to the steps of the process, simulating the whole industrial manufacturing procedure of the product, and outputting the KPI of the industrial manufacturing. At least one embodiment can evaluate the KPI of the whole industrial manufacturing procedure of the product according to the product model.

An on-demand digital manufacturing platform receives digital design files for a product and analyzes producibility of the product by at least one digital manufacturing technology based on whether a set of attributes of the digital design files satisfies producibility requirements for the manufacturing technology. If the attributes do not satisfy the producibility requirements, the platform generates a modified digital design that satisfies the producibility requirements. A customer can place an order for the product from the platform. In response, the platform selects a target fabrication machine to manufacture the product. The target fabrication machine can be selected based at least in part on a determined match between specifications of the target fabrication machine and fabrication parameters that are associated with manufacturing of the product based on the modified digital design. The modified design can then be sent to the target fabrication machine to manufacture the product.
