摘要
浆料直写(Direct Ink Writing)3D打印技术具有适用材料广泛、操作简单及成本低廉等优点,在材料3D打印成形领域得到了广泛应用,同时在陶瓷梯度构件成形方面也具有明显的优势.针对现有打印装置结构复杂及成形精度较低的问题,设计了一种机械结构简单的双挤出直写式打印机,实现较高精度的材料梯度渐变.重点阐述了挤出装置的整体结构,以及配套的连接电路和控制程序,通过挤出试验明确了打印速度和挤出流量之间的关系,从而实现了陶瓷梯度构件的高精度成形.结果表明:该挤出装置具有高精度、高可靠性的特点,为材料梯度构件的高精度成形研究奠定了良好的试验基础.
Abstract
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.
