3-D printing, which is an automated production process with layer-by-layer control, has been gaining rapid development in recent years. The technology has been adopted in the manufacturing industry for decades and has recently been introduced in the construction industry to print houses and villas. The technology can bring significant benefits to the construction industry in terms of increased customization, reduced construction time, reduced manpower, and construction cost. A few isolated products and projects have been preliminarily tested using the 3-D printing technology. However, it should be noted that such tests and developments on the use of 3-D printing in the construction industry are very fragmented at the time of the study. It is therefore necessary for the building and construction industry to understand the technology, its historical applications and challenges for better utilization in the future. A systematic review shows that 3-D printing technology, after years of evolution, can be used to print large-scale architectural models and buildings. However, the potential of the technology is limited by the lack of large-scale implementation, the development of building information modeling, the requirements of mass customization, and the life cycle cost of the printed projects. It is therefore expected that future studies should be conducted on these areas to consolidate the stability and expand the applicability of 3-D printing in the construction industry. 相似文献

为了全面分析中国3D打印混凝土技术的研究现状,从“油墨”材料、施工工艺和应用场景等方面对3D打印混凝土技术的研究进展进行了回顾,从时间和逻辑2条线路分析了该技术的发展历程,介绍了主要的施工工艺及在建筑物和基础设施上的应用案例,并分析了3D打印混凝土技术在生态“油墨”材料、仿生设计、大型打印设备开发及施工工艺、3D打印混凝土技术标准与验收规范等发展趋势。最后分析总结了目前中国3D打印混凝土技术所面临的问题,并结合实际应用场景给出了部分研究思路。结果表明:3D打印材料是影响混凝土性能最根本的因素,混凝土须具有更好的流变性能,并能够在环境中快速凝固; 现有3D打印混凝土设备还不能够完全满足不同应用环境的特殊性要求,需要在机械设计和施工流程方面进行协调开发,促进面向建筑领域新型3D打印设备的精细化与自动化发展; 3D打印混凝土结构和普通混凝土结构形式不同,现有的混凝土结构设计施工标准和国家规程并不适合3D打印混凝土技术,缺乏面向3D打印建筑的标准和验收规范; 企业、高校和科研机构需加强合作,以工程应用为导向指引3D打印混凝土的研究和发展。 相似文献

In recent few years, significant improvement has been made in developing largescale 3D printers to accommodate the need of industrial-scale 3D printing. It is of great feasibility to construct structural components and buildings by means of 3D concrete printing. The major issues of this innovative technique focus on the preparation and optimization of concrete materials which possess favourable printable properties as well as the measurement and evaluation methods of their workability. This paper firstly introduces three largescale 3D printing systems that have been successfully applied in construction industry. It then summarizes the commonly used raw materials in concrete manufacturing. Critical factors that should be particularly controlled in material preparation are specified. Easy-extrusive, easy-flowing, well-buildable, proper setting time and low shrinkage are significant for concrete mixture to meet the critical requirements of a freeform construction process. Thereafter, measuring methods that can be employed to assess the fresh and hardened properties of concrete at early stages are suggested. Finally, a few of evaluation methods are presented which may offer certain assistance for optimizing material preparation. The objective of this work is to review current design methodologies and experimental measurement and evaluation methods for 3D printable concrete materials and promote its responsible use with largescale 3D printing technology. 相似文献
