3D打印在琉璃研制生产方面的应用

Application of 3D printing in the development and production of colored glaze

琉璃颜色丰富,具有很高的观赏和收藏价值。但由于工艺过程复杂,琉璃制品原始数据获取途径十分单一,不利于琉璃产品的丰富。所以,数据获取方法的改进和生产流程简化,是未来琉璃生产必须解决的问题。通过3D打印蜡模将复杂琉璃一体化制造技术、三维数据反求技术和石膏型真空增压浇注技术结合,实现大型复杂琉璃产品的规模化和快速化生产。解决了琉璃研制过程中大型复杂形状琉璃数据获取和模样快速制作的难题以及3D打印成型蜡模与石膏型真空增压成型琉璃相结合的问题[1、2],改善了琉璃流动性差、凝固区间宽、线收缩大[3]导致的裂纹以及浇注系统胀型和脱模时间过长的问题。可将复杂形状琉璃生产周期从1~12个月缩短为10~15个工作日。

The colored glaze is rich in color and has a high ornamental and collection value. However, due to the complicated process, the raw data acquisition of glaze products is very simple, which is not conducive to the richness of glaze products. Therefore, the improvement of data acquisition methods and the simplification of production processes are issues that must be solved in the future of glass production. Through of 3D printing wax mold, the complex glaze integrated manufacturing technology, the three-dimensional data reverse technology and the gypsum vacuum press casting technology have been combined to realize the large-scale and rapid production of large-scale complex glass products. The problems of large-scale complex shape glaze data acquisition and rapid pattern production during the development of glaze have been solved, as well as the combination of 3D printing wax mold and gypsum vacuum pressure-molded glaze[1,2], which improves the poor fluidity, wide solidification interval and cracks caused by large width and line shrinkage[3] as well as excessive expansion and demolding time of the casting system. The production cycle of complex shape glaze can be shortened from 1 to 12 months to 10 to 15 working days.
