Design analysis and experimental study of direct ink writing gradient material 3D printing device
The Direct Ink Writing 3D printing technology with such advantages as a wide range of applicable materials,sim-ple operation and low cost is widely used in the field of material 3D printing and molding,and has obvious advantages in molding of ceramic gradient components.Since the current printing device suffers complex structure and low accuracy in molding,in this article a dual-extrusion direct-writing printer with simple mechanical structure is designed to achieve high-precision gradual change in material gradient.Efforts are made to expound the extrusion device's overall structure,as well as the supporting connection circuit and control program;the relationship between the printing speed and the extrusion flow is clarified through a series of ex-trusion experiment,so as to realize the high-precision molding of ceramic gradient components.The results show that the extrusion device has such characteristics of high precision and high reliability,which lays solid foundation for experiment and research on high-precision molding of material gradient components.
