摘要 黏结剂喷射(binder jetting, BJ)是一种将液态黏结剂喷射到粉末材料层上,选择性黏结粉末成形,随后进行致密化处理的增材制造技术。近年来,BJ技术因其高效率、低成本、适用材料范围广而受到广泛关注和研究。在BJ打印过程中,粉末特性、黏结剂及其与粉床的相互作用、打印参数等因素对生坯质量和性能有至关重要的影响。此外,烧结过程是影响最终部件质量的关键因素之一。本文总结了BJ打印的影响因素,提出可借助机器学习辅助坯体质量和烧结收缩预测,实现控形控性。目前,BJ技术正在推向汽车、医疗器械等行业。未来,BJ技术大规模应用的关键在于提高生坯质量和精度、增强黏结剂与坯体的结合强度、优化后处理工艺等方面。

Abstract:Binder jetting (BJ) is an additive manufacturing technology that involves jetting liquid binder onto the layers of powder materials to selectively bond the powder and form a shape, then followed by densification processing. In recent years, BJ technology has received widespread attention and research due to its high efficiency, low cost, and wide range of applicable materials. During the BJ process, factors such as powder characteristics, binder and its interactions with the powder bed, as well as printing parameters, have crucial impacts on the quality and performance of the green body. Additionally, the sintering process is one of the key factors affecting the quality of the final component. This study summarizes the influencing factors of BJ printing and proposes the use of machine learning to assist in predicting the green body quality and sintering shrinkage, enabling shape and property control. Currently, BJ technology is being promoted in industries such as automotive and medical devices. In the future,the key to the large-scale application of BJ technology lies in improving the quality and precision of the green body, enhancing the bonding strength between the binder and the body, and optimizing the post-processing techniques.
