| Abstract Scope |
Ceramic additive manufacturing (AM) offers the potential to create piezocomposite transducers with refined and customizable features that result in enhanced sensing performance for underwater acoustics. Novel geometries that are otherwise impossible to fabricate with conventional manufacturing methods may be efficiently created through AM processes to increase transducer sensitivity and improve directionality. The lithography-based ceramic manufacturing (LCM) process has been used to create innovative structures in PZT-5H. Broad material knowledge was used to create ceramic powders for slurry creation and to refine post-processing procedures for repeatable sintered material properties (density, dielectric constant, and piezoelectric coefficient) equivalent to conventionally produced bulk ceramic. Piezocomposite transducers produced with printed PZT were compared against conventionally manufactured replica transducers with excellent performance matching. Coupled-acoustic finite element analysis (FEA) was used to design and evaluate distributed composite apertures and auxetic structures with improved performance, which are only feasible to manufacture with AM. |
