摘　　要：针对含能材料液体3D打印的特点,搭建含能材料增材制造系统,设计了可根据需要变换喷出直径的喷头,并采用新型的气压方式控制含能材料的挤出速度,使气压大小与喷头直径相配合.该方法能有效保证含能材料打印的安全性.针对打印线不容易测量问题,提出基于视觉图像处理的打印线宽度测量方法,并在此基础上进行了乳化炸药类似物的打印试验,打印的模型各层黏结良好且基本符合形状要求,该系统用于液体增材制造可行.According to the features of the 3D liquid printing with energetic materials, this paper sets up an additive manufacturing system of energetic materials, designed the nozzle which can be changed according to the needs, and used pneumatic control to control the extrusion speed of energetic material. By controlling the air pressure size and to match the nozzle diameter, this method can effectively ensure the safety of the printing of energetic materials. Aiming at the problem that print line is difficult to measure, this paper put forward the method based on visual image processing proposing to measure the wire diameter which can effectively measure the width of printed lines. Besides, conducted a printing experiment of the emulsion explosive analogues. The model layers of print out bond well and basically conform to the model shape. Indicate that the liquid printing is feasible.
