许多快速制造技术针对逐层印刷或基于激光的原型。我们提出了WireFab，一个快速建模和原型系统，使用弯曲的金属丝作为结构框架。WireFab近似于相应虚拟皮肤网格的骨骼关节和皮肤外观，并且它允许用户通过以下方式来个性化设计：（1）指定关节位置和部分分割，（2）定义关节类型和运动范围以构建基于线的骨骼模型，以及（3）将分割的网格抽象为混合维度外观图案或附件。WireFab旨在允许用户选择如何最好地保持拓扑结构和关节运动的保真度，同时选择性地保持几何外观的保真度。与基于3D打印的高保真制造系统相比，WireFab通过忽略不必要的几何细节来提高原型制作速度，同时保持结构完整性和关节运动。此外，其他快速或低保真制造系统仅生产静态模型，而WireFab生产可摆位的铰接模型，并有可能实现比生产它们的机器更大的个性化功能产品。
Many rapid fabrication technologies are directed towards layer wise printing or laser based prototyping. We propose WireFab, a rapid modeling and prototyping system that uses bent metal wires as the structure framework. WireFab approximates both the skeletal articulation and the skin appearance of the corresponding virtual skin meshes, and it allows users to personalize the designs by (1) specifying joint positions and part segmentations, (2) defining joint types and motion ranges to build a wire-based skeletal model, and (3) abstracting the segmented meshes into mixed-dimensional appearance patterns or attachments. The WireFab is designed to allow the user to choose how to best preserve the fidelity of the topological structure and articulation motion while selectively maintaining the fidelity of the geometric appearance. Compared to 3D-printing based high-fidelity fabrication systems, WireFab increases prototyping speed by ignoring unnecessary geometric details while preserving structural integrity and articulation motion. In addition, other rapid or low-fidelity fabrication systems produce only static models, while WireFab produces posable articulated models and has the potential to enable personalized functional products larger than the machines that produce them.
