摘要/Abstract

摘要： 提出一种基于旋转喷头的四轴联动多材料同步3D打印技术方案，引入三喷嘴微喷头同时挤出三种材料，同时为喷头增加一个旋转自由度，当三种材料同步挤出时，喷头根据打印路径旋转，防止三种材料的打印路径重叠和材料干涉，实现三种材料的同步3D打印。基于上述方案，开发了专用的多材料挤出喷头和四轴联动同步3D打印设备。以Pluronic F127作为测试材料，制备了适合打印的浆料。研究了多材料的挤出气压组合、扫描速率、层厚对打印工艺的影响，优化了打印工艺参数，获得了效果良好的多材料打印结构，并通过各类图形验证了打印工艺的有效性。本研究提出的四轴联动多材料同步3D打印方法有望应用于多材料功能器件的一体化制备，推动3D打印技术在复杂功能器件领域的应用。

Abstract: A four-axis multi-material simultaneous 3D printing based on rotating nozzle is proposed. A print head with three nozzle micro-holes is introduced to print three types of materials simultaneously. In addition, a rotation motion freedom is introduced to avoid the overlapping and interference of the three materials during the printing process. Based on this idea, a multi-material extrusion print head and four-axis simultaneous printing machine are developed. Pluronic F127 is selected as the material to test the printing process and inks with appropriate rheological properties are prepared. The effects of printing pressures, scanning velocity, and layer thickness are investigated. The printing parameters are optimized and multi-material structures with good shapes and geometries are obtained. Furthermore, the printing process is validated by printing various complex geometries. The four-axis multi-material simultaneous 3D printing process proposed in this study can be utilized to fabricate multi-material functional devices in one-step, and push forward the applications of 3D printing in the fabrication of complex functional multi-material devices.
