Abstract: A computer-implemented method for designing a manufacturing product. The method including obtaining a set of materials for manufacturing the product, a set of use and/or manufacturing constraints for the manufacturing product, and specifications indicating an extent of compatibility of one or more reference materials with the constraints. The method further including determining an optimal subset of the set of materials for manufacturing the product. The determining includes classifying the materials with respect to compatibility with the constraints and based on the provided specifications. This constitutes an improved method for designing a manufacturing product.

Abstract: A computer-implemented method for 3D printing planning including obtaining a set of spare parts to be manufactured in one or more factories comprising 3D printers and other manufacturing machines. The method further including obtaining 3D printing constraints. The constraints include one or more constraints each representing a 3D printing constraint and/or a mechanical constraint for a spare part. The constraints further include one or more 3D printing capacity constraints for the one or more factories. The method further includes obtaining a reference set of one or more spare parts each classified either as compatible with the constraints or as non-compatible with the constraints. The method further includes determining an optimal subset of the set of spare parts to be 3D printed. The determining includes optimizing one or more objective manufacturing functions under the constraints and based on the reference set.
