Abstract
Traditional manufacturing methods for piezoelectric ceramic fabrication,such as press molding,slip casting,and machining,are hampered by their lack of design flexibility,innovation constraints,precision limitations,suboptimal material utilization,and inefficient production yields.To surmount these limitations,additive manufacturing(AM)has been introduced,leveraging a layer-by-layer construction mechanism.This comprehensive review examines the pros and cons of AM within the piezoelectric ceramic sector,highlighting its critical applications with a particular focus on the cutting-edge advantages of photopolymerization techniques like stereolithography(SLA)and digital light processing(DLP),and powder bed fusion(PBF)technologies,including selective laser sintering(SLS)and selective laser melting(SLM),for the precision manufacturing of intricate piezoelectric ceramic geometries.The review culminates with prospective insights into the refinement of AM technologies,such as the development of environmentally benign lead-free piezoelectric materials and integrated multifunctional design of piezoelectric materials.These advancements aim to expand their application horizons in areas such as sensor technology,energy harvesting systems,and biomedical engineering.关键词
