摘　　要：针对挤出式陶瓷3D打印用于制备铸造型壳,分析了不同层高下浆料的挤出与堆积情况。通过3D打印试验,对比研究了挤出口内径、层高和打印速度对打印过程及打印质量的影响,获得了合适的工艺参数值;对比研究了不同的空间倾斜角度、打印平面内的角度下打印件的质量,获得了打印件的空间最大倾斜角度和打印平面内的最小角度。结果表明,合适的工艺参数为挤出口内径0.6~0.8 mm,层高0.6 mm左右,打印速度20 mm/s;打印件的内、外最大倾斜角度为40°,打印平面内的最小角度为30°。The extrusion and accumulation of the slurry under different layer height were analyzed aiming at extrusion ceramic 3D printing for the preparing of casting shell.After 3D printing test,appropriate process parameter values were obtained by comparative studying the effect of extrusion head inner diameter,layer height and printing speed on printing process and printing quality,and the maximum space tilt angle and minimum angle in the printing plane of the printed part were obtained by comparative studying the quality of the printed part under different space tilt angle and the angle in the printing plane.The results show that appropriate process parameters are extrusion head inner diameter of 0.6 mm~0.8 mm,layer height of about 0.6 mm,printing speed of 20 mm/s.The maximum exterior and interior tilt angle of the printed part are 40°.The minimum angle in the printing plane of the printed part is 30°.
