目的 研究了熏香3D打印机的初级试验参数，达到为后续优化和批量生产提供技术规范和数据支持的目的。方法 基于课题组前期设计试制的熏香3D打印机进行试验，通过试验分析挤出压力、打印速度、出料口与打印平台的距离、模型复杂程度、出料口直径、水料混合比等参数对熏香3D打印机的打印效果和打印效率的影响，分析研究影响熏香打印机的主、次参数。结果 挤出压力为0.4～0.6 MPa，打印速度为1800～2400 mm/min时，打印效果较好；出料口与打印平台的最适宜距离为10～12 mm。结论 挤出压力与打印速度是影响熏香成型效果的最重要的2个因素。

The paper aims to research parameters for preliminary test of incense 3D printer to provide technical specifications and data support for subsequent optimization and mass production. Based on the experimental design of the incense 3D printer, the test was carried out to analyze the extrusion pressure, printing speed, distance between the discharge port and the printing platform, model complexity, outlet diameter, water mix ratio and other parameters. Their influences on printing effect and printing efficiency of the incense 3D printer were analyzed to analyze and research main and secondary parameters affecting the incense printer. When the extrusion pressure was 0.4 MPa to 0.6 MPa and the printing speed was 1800 mm/min to 2400 mm/min, the printing effect was better; the optimum distance between the discharge port and the printing platform was 10 mm to 12 mm. Extrusion pressure and printing speed are the two most important factors affecting the effect of incense molding.
