3D printing is rapidly becoming accessible and affordable, and may someday support a variety of manufacturing, craft, and creative jobs. However, a number of barriers remain to its more widespread use. One key barrier is the sequential nature of 3D printing workflows, in particular, the gap between modeling of the the shape to be printed and "slicing", developing a plan to create the model on a given 3D printing device. Most 3D printing tools separate these steps, which can cause wasteful printing or fundamental design problems if there is no easy way to render a particular model using a given device's capabilities; these problems are especially vexing for novice makers. This project will develop tools that provide both modeling and slicing capabilities and interfaces that help designers better consider device constraints and choose appropriate devices for their models. The team will leverage existing research on making slicing tools more efficient and ideas from how 2D design programs incorporate printer characteristics to address a number of challenges in integrating modeling and slicing. These include the need to rapidly generate slicing plans for a number of possible 3D printers, present feedback about potential problems that supports designers without overwhelming them, suggest alternative designs that address those problems, and understand how integrating these constraints affects designers' processes and abilities. In the course of the work, the team will produce a comprehensive catalog of 3D printing device characteristics that will support other research and design work in this space, as well as classes that will use the integrated tools to better teach the relationship between design decisions and design outcomes. The team will first classify different fabrication processes, devices, and materials available for 3D printing, then systematically analyze which fabrication parameters are useful to know about during 3D editing. They will both review existing products and manuals as well as interview experienced users about problems with fabrication that most affect their modeling, and develop a library of extensible, human- and machine-readable .xml files that incorporate these most relevant constraints. They will then study effective interaction models for such an integrated 3D editing environment. This includes both (1) how to present information about fabrication constraints, comparing the effectiveness of overlaid or parallel views of the rendered object alongside the 3D model mesh versus textual or audio warnings and (2) ways fabrication constraints might be embedded into how the tools work with users, such as snapping to grids based on the resolution of a selected device. Finally, they will explore how these interactions and tools might support seamless switching between different fabrication devices and plans for multiple-device environments such as makerspaces and fabrication labs. This entails developing semantic but device-independent annotations of a model's functional requirements as well as methods for generating and metrics for comparing a number of fabrication plans in order to suggest effective ones for a particular model. The goal is to leverage locality of design changes to make those methods fast enough to use not just at the end of modeling, but as a model is being constructed, allowing tools to present information about design choices that rule out or favor particular fabrication possibilities and the associated costs in time, materials, and money.

3D打印正迅速变得易于访问和负担得起，并且有一天可能会支持各种制造业，工艺和创意工作。 但是，许多障碍仍然更加广泛地使用。 一个关键的障碍是3D打印工作流的顺序性质，特别是在给定3D打印设备上创建模型的计划之间的建模与“切片”的建模之间的差距。 大多数3D打印工具将这些步骤分开，如果没有简单的方法可以使用给定设备的功能渲染特定型号，则可能会导致浪费的打印或基本设计问题；对于新手制造商来说，这些问题尤其令人烦恼。 该项目将开发提供建模和切片功能和接口的工具，并帮助设计师更好地考虑设备约束，并为其模型选择适当的设备。该团队将利用现有的研究来使切片工具更有效，并从2D设计程序结合打印机特征来解决整合建模和切片方面的许多挑战。其中包括需要快速生成许多可能的3D打印机的切片计划，提出有关潜在问题的反馈，这些问题支持设计师而不压倒它们，提出了解决这些问题的替代设计，并了解整合这些约束如何影响设计师的流程和能力。在工作过程中，团队将制作出3D打印设备特征的全面目录，该目录将支持该领域的其他研究和设计工作，以及将使用集成工具来更好地教授设计决策与设计成果之间关系的课程。该团队将首先对可用于3D打印的不同制造过程，设备和材料进行分类，然后系统地分析哪些制造参数在3D编辑期间很有用。他们将既将回顾现有的产品和手册，又要采访经验丰富的用户有关制造的问题，这些问题最影响其建模，并开发了可扩展，人类和机器可读的.x​​ml文件的库，这些文件包含这些最相关的约束。然后，他们将研究这种综合3D编辑环境的有效交互模型。这两者包括（1）如何提出有关制造约束的信息，将渲染对象的叠加或并行视图与3D模型网格与文本或音频警告以及（2）方式进行比较的有效性以及（2）方式可以将制造约束嵌入到工具中，例如基于用户的工具，例如基于所需设备的分辨率捕集的用户。 最后，他们将探讨这些交互和工具如何支持不同制造设备之间的无缝切换，以及用于多个设备环境（例如制造商空间和制造实验室）的计划。这需要开发模型功能需求的语义但与设备无关的注释，以及生成和指标的方法，用于比较许多制造计划，以便为特定模型建议有效的计划。目的是利用设计更改的局部性，以使这些方法不仅在建模结束时使用，而且还可以在建造模型时使用，允许工具提供有关设计选择的信息，这些信息排除或偏爱特定的制造可能性以及时间，材料和金钱的相关成本。
