3D打印技术在工程建设中的应用及前景

THE PROSPECTS AND APPLICATIONS OF 3D PRINTING FOR CONSTRUCTION

近年来,3D打印技术受到国内外技术人员的格外重视,在各行业中发展迅速,并逐步得到应用。通过惯3D打印技术在建筑工程中的应用的基础上,简要阐述3D打印技术的概念及其在建筑工程中应用的可行性,介绍了现有3D打印建筑的应用实例和设想,通过对3D打印结构力学性能的分析,对3D打印技术应用于建筑工程的前景进行展望。综述表明:将3D打印技术应用在工程建设领域既面临机遇也面临挑战。面临的挑战包括价格昂贵、需要建立对3D打印技术的性能评价体系等。提出未来的进一步发展需要政府、企业、研究单位的合作,共同推进3D打印技术在建筑工程的应用与普及。

In recent years, 3 D printing technology has gained special attention of researchers and engineers worldwide. It is developing fast and has been gradually put into application in various fields of industries.On the basis of summary summarized the application in construction engineering for 3 D printing technology the concept of 3 D printing technology was introduced and the feasibility application in construction engineering was briefly expounded. The engineering structures built with 3 D printing technology or to be built were introduced. Moreover, the paper also gave a review on the mechanical properties of structures built with 3 D printing technology. Finally, an outlook on 3 D printing technology with respect to construction engineering was presented. According to the literature review, there still existd some challenges in 3 D printing technology, including over-high cost, lack of performance evaluation system and so on. To promote the development of 3 D printing technology in the field of civil engineering, the paper suggested the government, enterprises and research institutes should work more closely in the future.
