摘要： 基于墨水直写式打印(direct ink writing，DIW)的3D打印技术使3D打印材料摆脱了材料属性的限制，为多种材料提供了实现增材制造的可能.为了保证打印成品件具有陶瓷材料优良的力学特性，对陶瓷材料的3D打印挤出成型过程中的各项工艺参数进行了研究.通过流体理论计算并使用Fluent对影响陶瓷材料小口径挤出过程的挤出速度、挤出口径等工艺参数进行了数值模拟，得到相关挤出工艺参数与挤出量之间的关系.基于数值模拟结果设计了包括电机挤出速度、挤出头口径、打印移动速度、打印层高度和激光固化功率为因素的试验，分析了各项工艺参数对挤出成型过程的不同影响.

Abstract: 3D printing technology based on direct ink writing(DIW) enables 3D printed materials to get rid of the limitation of material properties， and provides the possibility of additive manufacturing for a variety of materials. In order to ensure the excellent mechanical properties of ceramic materials， the technological parameters of 3D printing extrusion molding of ceramic materials were studied. According to the fluid theory calculations， Fluent was used to numerically simulate the process parameters such as the extrusion speed and the extrusion diameter that affect the small-diameter extrusion process of ceramic materials， and the relationship between the correlation extrusion process parameters and the extrusion amount was obtained. Based on the numerical simulation results， a test including motor extrusion speed， extrusion head caliber， printed moving speed， printed layer height， and laser curing power was given to analyze the different effects of various process parameters on extrusion forming processes.
