Abstract
A manufacturing a process is provided for the bulk manufacture of transducer arrays, including arrays having at least one 3D printed (or otherwise additive manufactured) acoustic matching layers. In certain implementations, the manufactured transducers include a composite-piezoelectric transducer on a de-matching layer. In one implementation, by producing multiple arrays at once on a common carrier, and by using direct-deposit additive processes for the matching layers, the described processes greatly reduce the number of parts and the number of manual operations.
