摘　　要：针对目前玻璃3D打印存在的打印模型不透明、打印效率低和打印成本高等不足,提出并构建了一种基于接触电阻加热的玻璃熔融沉积型(fused deposition modeling,FDM)3D打印系统.根据加热电阻模型确定了接触电阻与温度的关系,并搭建了基于接触电阻加热的3D打印系统,通过试验研究了加热温度、扫描速度和高温黏度等关键工艺参数对玻璃3D打印成型效果的影响规律.选择合适的工艺参数,可得到理想的沉积效果,并打印出几乎完全透明的不同形状的玻璃零件,这为玻璃3D打印提供了一种有效的打印方式以及为其参数选取提供了参考.这套设备体积小、成本低,是一款消费级的桌面玻璃3D打印系统.In this paper,for improving existing deficiencies that opaque printing modeling,inefficiency and high cost of glass 3D printing,a fused deposition modeling 3D printing system based on contact resistance heating is proposed and constructed.According to the heating resistance model,the relationship between contact resistance and temperature was determined,with a 3D printing system based on contact resistance heating fabricated.A series of tests were carried out on the key process parameters influencing 3D printing glass molding such as heating temperature,scanning speed and high temperature viscosity.Choosing the process parameters appropriately can achieve desired deposition result and print different shapes of glass parts that are almost transparent,which provides a printing method for glass 3D printing and a reference for test parameters selection.The device is a consumer-level desktop glass 3D printing system with small volume and low costs.
