在创建用于3D打印的物理模型时，物体的密度分布非常重要，因为它决定了物体的质量属性，例如质心，总质量和惯性矩。在本文中，我们提出了一种密度感知的形状建模方法来控制3D打印物体的质量属性。我们生成一个满足给定质量属性的连续密度分布，并生成一个3D打印模型，该模型使用桁架结构表示该密度分布。迭代优化节点的数量和它们的位置，以便最小化目标密度和桁架结构的密度之间的误差。通过我们的技术，可以制造具有所需质量特性的3D打印物体。
When creating a physical model to 3D print, the density distribution of an object is important because it determines the mass properties of objects such as center of mass, total mass and moment of inertia. In this paper, we present a density aware shape modelling method to control the mass properties of 3D printed objects. We generate a continuous density distribution that satisfies the given mass properties and generate a 3D printable model that represents this density distribution using a truss structure. The number of nodes and their positions are iteratively optimized so as to minimize error between the target density and the density of the truss structure. With our technique, 3D printed objects that have desired mass properties can be fabricated.
