摘　　要：为研制一种圆柱坐标式多材料食品3D打印设备,对其挤出、成型及多材料等工艺参数进行试验研究。以马铃薯泥混合材料为打印原材料,利用搭建的样机进行工艺参数试验。结果表明:打印喷嘴高度在1.1~1.6 mm,喷嘴直径大于0.8 mm,挤出速度与打印速度相匹配,具有良好的挤出特性;打印速度对产品成型尺寸偏差的影响最大,单层层厚对产品表面质量及成型效率的影响最大;快速、均衡及高精3种工况下,多材料的最佳回抽时间分别为12.5,14.5,15.0 s。研究为确定及优化圆柱坐标式多材料食品3D打印设备的工艺参数提供指导。A cylindrical coordinate multi-material food 3D printing equipment was developed,and the optimal process parameters such as extrusion,molding and multi-material were studied experimentally.The mixed material of mashed potato was used as the printing raw material,and the process parameter test was carried out by using the built prototype.The experimental results show that when the printing nozzle height is 1.1~1.6 mm,the nozzle diameter is greater than 0.8 mm,and the extrusion speed matches the printing speed,it has good extrusion characteristics.The printing speed has the greatest influence on the dimensional deviation of the product,and the thickness of the single layer has the greatest influence on the surface quality and forming efficiency of the product.The optimal re-pumping time of multi-materials under fast,balanced and high-precision conditions is 12.5,14.5,15.0 s,respectively.This study provides guidance for determining and optimizing the process parameters of cylindrical coordinate multimaterial food 3D printing equipment.
