不同参数对石膏3D打印模型性能的影响

通过正交试验研究了墨滴体积、层厚、分辨率、粉末目数对工业级石膏3D打印模型的抗拉强度、抗折强度、尺寸精度的影响,确定了石膏3D打印的最佳工艺参数:墨滴体积65 pL,层厚0.15 mm,分辨率0.06 mm,粉末目数150目,铺粉轴速度100 m/s,喷墨频率8000 Hz,负压31 MPa,振动电机频率108 r.按...

The Influence of Different Parameters on the Performance of Gypsum 3D Printing Model

The influence of ink drop volume,layer thickness,resolution and powder mesh number on the tensile strength,flexural strength and dimensional accuracy of industrial-grade gypsum 3D printing models were studied through orthogonal experiments.The best gypsum 3D printing process parameters was determined:ink droplet volume 65 pL,layer thickness 0.15 mm,resolution 0.06 mm,powder mesh number 150,powder spreading shaft speed 100 m/s,inkjet frequency 8000 Hz,negative pressure 31 MPa,vibration motor frequency 108 r.According to this parameter,the 3D printing model not only had a high strength,which was good for the post-processing of powder cleaning,not easy to break,and good for transportation,but also had high dimensional accuracy and smooth surface quality,which could fully demonstrate the advantages of gypsum printing.
