摘要/Abstract

摘要： 水泥基复合材料的3D可打印性与打印工艺的协调兼容是无模快速建造成型的关键。然而,3D打印原材料和配合比多样,打印设备不同,成型工艺各异,且3D可打印性的量化与评估尚未形成统一标准,为该技术的工程应用和推广带来不便。本文分析了3D可打印性的影响因素,综述了混凝土3D可打印性的量化评价方法,总结分析了六种3D可打印性的优化提升方法,并给出了标准化推广的建议,对混凝土3D打印技术的工程应用具有实践指导价值。

Abstract: The coordination between the 3D printability of cementitious composites and printing process is crucial to the rapid additive manufacturing. However, due to the variety of raw materials and mix proportion, printing equipment and manufacturing process, etc., the quantification and evaluation of 3D printability have not been unified, which brings barriers to the application and promotion of this technology in engineering practices. The influencing factors of 3D printability are analyzed, the quantitative evaluation methods of concrete 3D printability are summarized, six optimization methods of 3D printability are summarized and analyzed, and suggestions for standardization promotion are provided, which provide practical guidance value for the engineering application of 3D concrete printing technology.

Key words: 3D printing concrete, 3D printability, quantitative indicator, optimization method, standardization promotion
