Workshop on Additive Manufacturing (3D Printing) for Civil Infrastructure Design and Construction; Arlington, Virginia; July 13-14, 2017

该奖项将支持一个研讨会，以促进用于民用基础设施设计和施工的增材制造（也称为3D打印）的研究议程。民用基础设施包括建筑物、住宅、地下结构、公用事业网络/设备以及构成建筑环境的其他结构。本次研讨会将于2017年7月13日至14日在弗吉尼亚州阿灵顿的国家科学基金会举行。作为一项快速发展的技术，3D打印有望从根本上改变制造业的性质，并在21世纪彻底改变许多研究领域。本次研讨会旨在探索3D打印在民用基础设施设计和施工领域的新研究前沿。研讨会将为来自增材制造、建筑、岩土和结构工程、建筑和材料领域的研究人员提供一个互动场所，以解决技术挑战并确定研究重点，以加速3D打印在民用基础设施设计和施工中的广泛应用。这反过来又有助于提高美国制造业的竞争力，提高民用基础设施设计和建设的成本效益，延长国家基础设施的弹性，并在美国相关领域创造就业机会。为期两天的研讨会的目标包括：(a)回顾与民用基础设施设计和施工相关的不同工程领域的3D打印技术，(b)分享联邦机构对民用基础设施设计和施工3D打印的观点，(c)确定在民用基础设施设计和施工中使用3D打印的差距和挑战，以及(d)提出研究优先事项的建议。讲习班将包括三项活动：(a)邀请来自不同工程部门的专家介绍3D打印案例研究，并邀请联邦机构的代表介绍其机构在土木基础设施设计和施工相关领域对3D打印的看法；(b)由发言人主持的小组讨论，讨论技术挑战和潜在的技术转让；及(c)由参加者作思想分享演讲，分享3D打印在土木基础设施设计和建造方面的最新技术和优势。讲习班的成果将在一份讲习班报告中提供。

This award will support a workshop to facilitate a research agenda for additive manufacturing (also known as 3D printing) for civil infrastructure design and construction. Civil infrastructure includes buildings, residential homes, underground structures, utility networks/equipment, and other structures that comprise the constructed environment. This workshop will be held at the National Science Foundation in Arlington, Virginia, on July 13-14, 2017. As a rapidly growing technology, 3D printing is expected to fundamentally change the nature of manufacturing and revolutionize many areas of research in the 21st century. This workshop aims to explore a new research frontier for 3D printing in the area of civil infrastructure design and construction. The workshop will provide an interactive venue for researchers from communities of additive manufacturing, architecture, geotechnical and structural engineering, construction, and materials to address technological challenges and identify research priorities to accelerate a wide adoption of 3D printing for civil infrastructure design and construction. This, in turn, can help enhance U.S. competitiveness in manufacturing, increase cost effectiveness of civil infrastructure design and construction, prolong resilience in national infrastructure, and create jobs in related fields in the United States.The objectives of the two-day workshop include: (a) review of the state-of-the-art of 3D printing in different engineering sectors related to civil infrastructure design and construction, (b) sharing of perspectives on 3D printing for civil infrastructure design and construction from federal agencies, (c) identification of gaps and challenges in using 3D printing for civil infrastructure design and construction, and (d) formulation of recommendations for research priorities. The workshop will be composed of three activities: (a) invited talks given by experts who will present 3D printing case studies from different engineering sectors and by representatives from federal agencies who will talk about their agency's perspectives on 3D printing in areas related to civil infrastructure design and construction, (b) panel discussions led by speakers addressing technical challenges and potential technology transfer, and (c) idea sharing presentations given by participants who will share insights about the state-of-the-art and advantages of 3D printing for civil infrastructure design and construction. The outcomes of the workshop will be made available in a workshop report.
