Fabrication of materials with desired characteristics from base materials having determined characteristics

摘要

In an object generation system, consumable base materials are characterized in a characterization process wherein an object generation system can use a plurality of so-characterized base materials. User input representing a desired object and set of characteristics for that desired object are processed, using a computer or computing device, to derive a mapping of locations for placement of portions of the plurality of base materials such that when the mapping is provided to an object generator, the generated object approximates the representing a desired object and set of characteristics. The characterization of a base material might include elasticity of the base material, the user input might be a desired shape and elasticity, the object generator might be a 3D multi-material printer and the generated object might at least approximate the desired shape and elasticity as a result of being constructed from the plurality of base materials used by the printer.

主权项

1. A method, using a computer, for generating a recipe for generating a physical object, the method comprising:
determining material characteristics of a plurality of base materials; determining a set of characteristics of a target object, wherein one of the set of characteristics is affected by a material property of at least one material in the target object; generating a model of the physical object; calculating locations of a plurality of the base materials in the model of the physical object, wherein the plurality of locations are calculated to approximate the desired set of characteristics of the target object when some of the base materials are placed at the calculated locations; and outputting instructions for generating an object from located portions of the plurality of base materials.
