Aluminum nitride (AlN) ceramics exhibit exceptional properties that render them highly valuable for diverse industrial applications. However, conventional manufacturing techniques encounter significant challenges in fabricating complex AlN components with precise geometries. To address these limitations, digital light processing (DLP) has emerged as a promising additive manufacturing approach for AlN ceramics. This study presents a systematic investigation of the monomer composition in the photopolymer resin system through a comprehensive experimental evaluation. The results demonstrate that an optimized mixture of monomers ACMO (56.7 wt%), DEGDA (2.7 wt%), and TMPTA (40.6 wt%) yields photopolymer resin with superior comprehensive performance. Utilizing this optimized formulation, a 50 vol% solid loading AlN ceramic slurry was successfully prepared, and subsequently, dense AlN ceramic components were fabricated through DLP. This provides an important basis for optimizing the slurry preparation of AlN ceramic fabrication based on DLP 3D printing.
氮化铝(AlN)陶瓷具有卓越的性能,使其在各种工业应用中具有很高的价值。然而,传统制造技术在制造具有精确几何形状的复杂AlN部件时面临重大挑战。为了解决这些限制,数字光处理(DLP)已成为一种有前途的用于AlN陶瓷的增材制造方法。本研究通过全面的实验评估,对光聚合物树脂体系中的单体组成进行了系统研究。结果表明,单体ACMO(56.7 wt%)、DEGDA(2.7 wt%)和TMPTA(40.6 wt%)的优化混合物可产生具有优异综合性能的光聚合物树脂。利用这种优化配方,成功制备了50 vol%固体含量的AlN陶瓷浆料,随后通过DLP制造出致密的AlN陶瓷部件。这为基于DLP 3D打印优化AlN陶瓷制造的浆料制备提供了重要依据。
