Abstract

The flow and deformation of cement-based materials accompanies the full cycle of 3DPC technology and profoundly affects the quality of printed structures. Therefore, rheology is closely related to this technology. However, since printing materials undergo complex changes (from fluid to solid) during the entire technical process, it is extremely difficult to accurately obtain the rheological parameters of the material, which makes it difficult to characterize the material properties and explore the rheological laws within the technical cycle. In this regard, this article starts from the perspective of rheology, systematically reviews the performance requirements of 3DPC technology for printing materials, critically discusses the existing methods for characterization of material printability, including various conventional and unconventional methods, and clarifies the scope of application of each method. In addition, this article introduces several buildability models based on considering material time dependence, pointing out the direction for the performance optimization of printing materials.

从流变学角度看 3D 打印混凝土技术：综述

水泥基材料的流动和变形伴随着 3DPC 技术的整个周期，并深刻影响着打印结构的质量。因此，流变学与这项技术密切相关。然而，由于打印材料在整个技术过程中会发生复杂的变化（从流体到固体），要准确获得材料的流变参数极其困难，这就给表征材料特性和探索技术周期内的流变规律带来了困难。为此，本文从流变学的角度出发，系统回顾了 3DPC 技术对打印材料的性能要求，批判性地讨论了现有的材料打印性表征方法，包括各种常规和非常规方法，并明确了每种方法的适用范围。此外，本文还在考虑材料时间依赖性的基础上介绍了几种可构建性模型，为打印材料的性能优化指明了方向。
