NSF/DARPA DDFRP: Reduced Instruction Design for Solid Freeform Fabrication

该奖项支持通过开发一种用于分离设计和制造功能的语言来加强固体自由成形制造（SFF）的应用和使用的研究。 SFF是一种新兴技术，可以快速制造几乎不受限制的几何设计零件。 本研究 涉及三个主题：（1）开发一种精简指令功能说明语言，它包括一个用于说明功能性能的基本词汇和组合该词汇的基本元素以产生完整系统说明的机制;（2）一种综合方法学，用于产生满足功能要求的设计描述， 在一个统一的并行框架中将设计的概念、几何抽象、理想化、网格生成、仿真和优化阶段结合在一起;以及（3）设计和制造之间的数字接口的封装交换格式。 这项研究的成功完成将大大提高 SFF技术的出现。 这些技术可以大大增强设计人员的能力，特别是通过扩大可以制造的设计范围，它们将大大缩短新产品的上市时间。 这些进步将大大提高美国工业的竞争力。

This award supports research to enhance the application and use of solid freeform fabrication (SFF) through the development of a language for the separation of the design and fabrication functions. SFF is an emerging technology that enables the rapid fabrication of a nearly unrestricted range of geometrically designed parts. This research addresses three topics: (1) the development of a reduced instruction functional specification language consisting of a basic voca`ulary for specifying functional performance and mechanisms for combining primitive elements of this vocabulary to produce complete system specifications; (2) a synthesis methodology to generate design descriptions satisfying functional requirements that will bring together the conception, geometric abstraction, idealization, mesh generation, simulation, and optimization stages of design in a unified concurrent framework; and (3) an encapsulated interchange format for the digital interface between design and fabrication. The successful completion of this research would greatly enhance the emergence of SFF technologies. These technologies could provide substantially enhanced capability to designers, particularly by expanding the range of designs that can be fabricated, and they would significantly reduce the time to market for new products. These advances would greatly improve the competitiveness of U.S. industry.
