Despite the increasing availability of personal fabrication hardware and services, the true potential of digital fabrication remains unrealized due to lack of computational techniques that can support 3D shape design by non-experts. This work develops computational methods that address two key aspects of content creation:(1) Function-driven design synthesis, (2) Design assessment. For design synthesis, a generative shape modeling algorithm that facilitates automatic geometry synthesis and user-driven modification for non-experts is introduced. A critical observation that arises from this study is that the most geometrical specifications are dictated by functional requirements. To support design by high-level functional prescriptions, a physics based shape optimization method for compliant coupling behavior design has been developed. In line with this idea, producing complex 3D surfaces from flat 2D sheets by exploiting the concept of buckling beams has also been explored. Effective design assessment, the second key aspect, becomes critical for problems in which computational solutions do not exist. For these problems, this work proposes crowdsourcing as a way to empower non-experts in esoteric design domains that traditionally require expertise and specialized knowledge.

赋能非数字制造专家的计算设计和评估方法

尽管个人制造硬件和服务的可用性越来越高，但由于缺乏可以支持非专家 3D 形状设计的计算技术，数字制造的真正潜力仍未实现。这项工作开发了解决内容创建的两个关键方面的计算方法：(1) 功能驱动的设计综合，(2) 设计评估。对于设计合成，引入了一种生成形状建模算法，该算法有助于非专家的自动几何合成和用户驱动的修改。从这项研究中得出的一个重要观察结果是，大多数几何规格是由功能要求决定的。为了支持高级功能规定的设计，开发了一种基于物理的形状优化方法，用于柔顺耦合行为设计。根据这个想法，还探索了通过利用屈曲梁的概念从平面 2D 板生产复杂的 3D 表面。有效的设计评估是第二个关键方面，对于不存在计算解决方案的问题变得至关重要。对于这些问题，这项工作提出了众包作为一种方式，可以在传统上需要专业知识和专业知识的深奥设计领域赋予非专家权力。
