3D打印机为物体的形状和机械功能的原型制作提供了非凡的灵活性。我们研究了如何修改3D模型，以方便创建提供动态输入和输出的交互式对象。我们介绍了一种通用的技术，用于支持交互性的快速原型，从3D模型中删除内部材料，形成内部管道。我们描述了这种新的设计空间的管道交互设计，其中变量包括开口，路径约束，拓扑结构和插入的媒体。然后，我们提出了PipeDream，一个工具，用于路由这样的管道通过内部的3D模型，集成在一个3D建模程序。我们使用两种不同的路由算法。第一种是让用户定义管道的终端，并使用路径路由和基于物理的模拟来最大限度地减少管道弯曲能量，从而允许打印后轻松插入介质。第二个允许用户提供所需的内部形状，我们适合管道路由：为此，我们描述了一个图形路由算法。我们提出了几个使用我们的工具创建的原型，以显示其灵活性和潜力。
3D printers offer extraordinary flexibility for prototyping the shape and mechanical function of objects. We investigate how 3D models can be modified to facilitate the creation of interactive objects that offer dynamic input and output. We introduce a general technique for supporting the rapid prototyping of interactivity by removing interior material from 3D models to form internal pipes. We describe this new design space of pipes for interaction design, where variables include openings, path constraints, topologies, and inserted media. We then present PipeDream, a tool for routing such pipes through the interior of 3D models, integrated within a 3D modeling program. We use two distinct routing algorithms. The first has users define pipes' terminals, and uses path routing and physics-based simulation to minimize pipe bending energy, allowing easy insertion of media post-print. The second allows users to supply a desired internal shape to which we fit a pipe route: for this we describe a graph-routing algorithm. We present several prototypes created using our tool to show its flexibility and potential.
