摘要：添加剂制造（印刷）是常用的物理模型的广泛应用，从考古学的设计。而静态模型直接支持，这是可取的，也能够打印模型功能，如手关节和关节，不需要手工装配组件。除了有解决的固有限制的印刷过程，这构成了特殊的挑战阐述模型应该是各种：允许模型保持一个姿势，关节需要表现出内部摩擦承受重力，没有他们的部分融合在三维印刷。这不可能与以前的可打印的联合设计。在本文中，我们提出一个方法的三维模型转化成可打印的，功能性，非模型内部摩擦。为此，我们设计了一个直观的工作，需要一个适当fl操纵三维模型，自动fi其小说3d-printable和各种接头，并提供一个接口指定转动约束。我们表明一些结果不同的模型阐述，证明的效力，我们的方法。



Abstract：Additive manufacturing (3D printing) is commonly used to produce physical models for a wide variety of applications, from archaeology to design. While static models are directly supported, it is desirable to also be able to print models with functional articulations, such as a hand with joints and knuckles, without the need for manual assembly of joint components. Apart from having to address limitations inherent to the printing process, this poses a particular challenge for articulated models that should be posable:to allow the model to hold a pose, joints need to exhibit internal friction to withstand gravity, without their parts fusing during 3D printing. This has not been possible with previous printable joint designs. In this paper, we propose a method for converting 3D models into printable, functional, non-assembly models with internal friction. To this end, we have designed an intuitive workflow that takes an appropriately rigged 3D model, automatically fits novel 3D-printable and posable joints, and provides an interface for specifying rotational constraints. We show a number of results for different articulated models, demonstrating the effectiveness of our method.
