The research objective of this EArly concept Grant for Exploratory Research (EAGER)is the creation of a research-driven framework for developing, integrating, and evaluating digital fabrication technologies with biologically inspired form generation to support sustainable construction. Functionally Graded Rapid Fabrication (FGRF) is a novel design approach and technological framework enabling the controlled spatial variation of material properties through continuous gradients in functional components. The work will provide research-based evidence for variable-property form generation informed by environmental performance criteria such as variable-density concrete beams and variable-elasticity polymer panels. Spatial variations of material properties are traditionally achieved as discrete delineations in physical behavior by fabricating multiple parts comprised of different materials, and assembling them only after the fabrication process has been completed. Recent advances in Computational Topology Design (CTD) and Solid Free-Form Fabrication (SFF) are promoting the creation of building components with controlled micro-, and macro-architectural features. The FGRF approach will combine a novel software environment with a mechanical output tool designed as a 6-axes, 3-D printer to allow computer control of material distribution within a monolithic structure. If successful, the project will advance the ability of machines to fabricate with variable properties, and will enable the control of their variation according to the desired environmental input. The new approach will expand current fabrication platforms and will be a significant first step toward variable property digital fabrication. Being the first FGM construction technology, the project has the potential to lead to a line of new research. This interdisciplinary award makes contributions to the fields of digital fabrication, computer-aided design, material science and mechanical engineering. As a novel research platform, the FGRF approach has the potential for reaching a large number of designers, engineers and scientists operating at the intersection of digital design innovation and sustainable construction. Through far-reaching collaborations applying new expertise and engaging novel interdisciplinary perspectives across MIT, the investigator will not only invent these tools and discover how to use them, but lead their translation into design applications while evaluating their contribution to a radically new approach in sustainable design & construction. Long term, this research is also expected to contribute to understanding the theory and practice of sustainable rapid fabrication of variable-property construction. Results will be distributed in all of these communities through peer-reviewed publications and conference presentations, as well as through physical installations and demonstrations.

这项早期探索性研究概念赠款（急切）的研究目标是创建一个以研究驱动的框架来开发，整合和评估数字制造技术与生物学启发的形式，以支持可持续结构。功能分级的快速制造（FGRF）是一种新型的设计方法和技术框架，可以通过功能组件中的连续梯度对材料特性的控制空间变化。 这项工作将提供基于研究的证据，以通过环境性能标准（例如可变密度混凝土束和可变弹性聚合物面板）告知可变的形式。传统上，通过制造由不同材料组成的多个零件，仅在制造过程完成后将其组装而成，从而将物质特性的空间变化视为物理行为的离散描述。计算拓扑设计（CTD）和固体自由形式制造（SFF）的最新进展正在促进具有控制的微型和宏观构造特征的建筑组件的创建。 FGRF方法将将新颖的软件环境与设计为6轴，3D打印机设计的机械输出工具相结合，以允许计算机控制整体结构内的材料分布。如果成功，该项目将提高机器使用可变属性制造的能力，并根据所需的环境输入能够控制其变化。新方法将扩大当前的制造平台，并将是迈向可变属性数字制造的重要第一步。该项目是第一个FGM建筑技术，有可能导致一系列新的研究。该跨学科奖为数字制造，计算机辅助设计，材料科学和机械工程的领域做出了贡献。作为一个新颖的研究平台，FGRF方法具有潜力，可以吸引在数字设计创新和可持续结构的交汇处运营的大量设计师，工程师和科学家。通过采用新的专业知识和吸引新颖的跨学科观点的深远合作，研究人员将不仅发明这些工具并发现如何使用它们，而且将其转化为设计应用，同时评估其对可持续设计和构建中一种彻底新方法的贡献。从长远来看，这项研究还预计将有助于理解可持续快速制造可变质体结构的理论和实践。结果将通过同行评审的出版物和会议演示以及通过物理装置和演示在所有这些社区中分发。
