Abstract

This article discusses in detail the preparation technology and performance optimization of cement-based composite materials for 3D printing. Analyze the selection of preparation materials, clarify the types and performance requirements of raw materials, and propose selection criteria and proportion principles. Detailed discussion on the influencing factors during the preparation process, including raw material properties, preparation process parameters, and the impact of preparation environment on material properties. A comprehensive performance characterization system has been established to comprehensively characterize the physical properties, mechanical properties, durability, and printability of cement-based composite materials for 3D printing. Based on the performance characterization results, optimization strategies such as raw material ratio optimization, preparation process parameter adjustment, selection and application of additives, and performance testing and feedback adjustment were proposed to achieve performance improvement of cement-based composite materials for 3D printing. This study aims to prepare high-performance cement-based composite materials for 3D printing through scientific selection and proportioning of raw materials, optimized preparation processes, and reasonable application of additives. At the same time, by characterizing the performance of the system and adjusting feedback, the material's performance is continuously improved to meet the needs of 3D printing technology. This study not only provides theoretical guidance for the preparation of cement-based composite materials for 3D printing, but also provides reference for further research in related fields.
