Abstract Scope Piezoelectric structures were created from soft PZT-5H using lithography-based ceramic manufacturing (LCM). LCM uses digital light projection (DLP) to form green ceramic parts with customizable geometry and high resolution from a photocurable slurry. LCM imparts minimal stress on green parts compared with conventional methods, enabling repeatable creation of periodic structures. Powder preparation and thermal-processing methods were developed to yield sintered LCM parts with density, dielectric constant, and piezoelectric charge coefficient (d33) comparable to conventionally manufactured PZT-5H. An LCM 1-3 piezocomposite resonant at 88 kHz was fabricated into a simple transducer and compared to an equivalent conventional PZT transducer. Modeling and simulation predicted the acoustic performance of the AM and traditional material, laying groundwork to develop novel piezocomposite designs. Feasibility of the creation of novel piezocomposite structures developed through modeling and produced via LCM was demonstrated, with potential to streamline manufacturing processes of piezoelectric ceramics and augment performance in acoustic transducers.
