精确控制打印层的形状，消除弯曲的侧面和内部应力集中，并提高机械性能，对于保证3D打印水泥基结构的质量至关重要。本工作旨在通过专门设计的成型板装置来实现上述目标。系统研究了SP-3DPC打印结构中的压力（应力）分布，以及SP-3DPC的截面形状、微观结构和力学性能。结果表明，使用成型板装置虽然会使打印速度略有降低，但能有效地抑制挤出物的自由膨胀，控制其截面几何形状，提高打印结构的表面光洁度和力学性能。该研究为成型板装置的设计和应用提供了理论依据和技术指导。
Precisely controlling the shape of the printed-layers, eliminating the curved sides and internal stress concentration, and increasing the mechanical properties are essential to guarantee the quality of 3D printed cement-based structures. This work aims at achieving the above-mentioned targets through a specially designed shaping plate apparatus. The pressure (stress) distribution in the printed structure with a shaping plate apparatus (SP-3DPC), and the cross-sectional shape, microstructure and mechanical properties of SP-3DPC were systematically investigated. Results indicate that using the shaping plate apparatus may slightly reduce the printing speed, but it can effectively constrain the free expansion of extrudate, control its cross-sectional geometry, and improve the surface finish quality and mechanical properties of the printed structure. This study provides a theoretical basis and technical guidance for the design and application of the shaping plate apparatus.
