摘要
玻璃作为一种非晶态材料,具有高光学透明度、高热稳定性、高化学稳定性、高熔点及低热膨胀系数等特点,广泛用于电子、信息、医疗等领域.随着人们对玻璃材料的结构形状、材料分布及功能属性要求越来越高,传统的玻璃材料成形加工方法(浇筑法、吹制法、浮法等)很难甚至无法满足上述需求.3D打印技术颠覆了传统材料的成形工艺,其基于逐层累加的制造原理,理论上可实现任意复杂构件的数字化成形,具有无需模具、成形效率高等优点,受到玻璃材料成形制造领域学者的广泛关注.本文系统总结了玻璃材料构件的不同3D打印工艺方法、原理及优缺点,介绍了 3D打印玻璃材料的应用现状,最后对玻璃材料3D打印技术进行了展望.
Abstract
As an amorphous material with high optical transparency,high thermal and chemical stability,high melting point and low coefficient of thermal expansion,glass is widely used in optics,biology,medicine and other fields.With the increasingly high requirements for the structure,material distribution and functional properties,traditional glass material processing methods(such as casting,blowing,floating,etc.)are difficult or even impossible to meet the above requirements.The emergence of 3D printing technology has subverted the traditional material forming process,which is based on the manufacturing principle of layer-by-layer accumulation,and theoretically can realize the digital forming of any complex components,with no molds,forming efficiency and other advantages.3D printing technology has been widely concerned by the scholars in the field of glass material forming and manufacturing.This review systematically summarizes the 3D printing processes,principles,and their advantages and disadvantages for glass materials.Discussions are then presented on the applications of 3D printing glass materials.Finally,the future development is presented for the 3D printing technology of glass materials.
