摘要： System and method for optimizing a three-dimensional model representing a shape of an object to be fabricated from a plurality of materials having known physical properties. The object is designed to exhibit one or more target properties and the three-dimensional model includes a plurality of cells. The system includes at least one processor programmed to receive a data structure including information for a material property gamut of microstructures for the plurality of materials and two or more of the known physical properties of the plurality of materials, and perform a topology optimization process on the three-dimensional model to generate an optimized model, wherein the topology optimization process is constrained based, at least in part, on the information in the received data structure and the one or more target properties.

摘要： According to some aspects, a method of designing an object based on a three-dimensional model representing a shape of the object is provided. The object may be fabricated from a plurality of materials having one or more known physical properties, wherein the object is designed to exhibit one or more target properties. The method may comprise determining a first composition of the object by providing the three-dimensional model as input to a reducer tree, determining one or more physical properties of the object with the first composition by simulating the object with the first composition, comparing the determined one or more physical properties with the one or more target properties, and determining a second composition of the object based on a result of comparing the determined one or more physical properties with the one or more target properties.
摘要翻译：根据一些方面，提供了一种基于表示对象的形状的三维模型来设计对象的方法。该物体可以由具有一种或多种已知物理性质的多种材料制造，其中该物体被设计为展现一种或多种目标性质。该方法可以包括通过将三维模型作为输入提供给减速器树来确定对象的第一组合，通过用第一组合模拟对象来确定具有第一组合的对象的一个或多个物理属性，将所确定的一个或多个具有所述一个或多个目标属性的物理属性，以及基于将所确定的一个或多个物理属性与所述一个或多个目标属性进行比较的结果来确定所述对象的第二组成。
