摘　　要：利用FLIR热成像仪扫描得到3D打印机喷头散热片热量云图,对影响热量分布情况以及打印质量的打印参数进行了分析,结果表明:当加热温度确定时,散热片与室温之间的温差随着风扇转速的增加而降低,当风扇转速确定时,散热片与室温之间的温差随着喷头加热温度的增加而升高;中间轴线处的温度最高,依次向四周递减;结合温差分布以及打印质量得出打印机最优参数设置为加热温度220℃、散热风扇转速200 r/min。Use FLIR thermal imager to scan to obtain the heat cloud image of the heat sink of the 3 D printer nozzle, and analyze the printing parameters that affect the heat distribution and print quality. The analysis results show that when the heating temperature is determined, the temperature difference between the heat sink and the room temperature decreases as the fan speed increases;when the fan speed is determined, the temperature difference between the heat sink and the room temperature increases as the heating temperature of the nozzle increases;the temperature at the middle axis is the highest, and it decreases gradually to the surroundings. Combining the temperature difference distribution and the print quality, it is concluded that the printer’s optimal parameters are set to a heating temperature of 220°C and a cooling fan speed of 200 r/min.
