Abstract
An additively manufactured multilayered structure including a first ceramic layer, the first ceramic layer including a ceramic powder having piezoelectric characteristics and a second ceramic layer built over the first ceramic layer, the second ceramic layer includes a second layer of ceramic powder has piezoelectric characteristics built on the first layer. At least a portion of the second ceramic layer is sintered and set over the first layer.

A method for additively manufacturing a layered composite structure the method comprising:
- building a first ceramic layer from ceramic powder having piezoelectric characteristics, constructing the first ceramic layer includes:
- depositing a first layer of ceramic powder, wherein the layer of ceramic powder includes a plurality of ceramic particles;
- sintering at least a portion of the first layer of the ceramic powder, wherein sintering the portion of the first layer of ceramic powder melts the plurality of ceramic particles;
- and
- setting the portion of the first layer, wherein setting the portion of the first layer forms the first ceramic layer having piezoelectric characteristics;
- and
- building a second ceramic layer over the first ceramic layer, constructing the second ceramic layer includes:
- depositing a second layer of ceramic powder on the first ceramic layer;
- sintering at least a portion of the second layer of the ceramic powder, wherein sintering the portion of the second layer of ceramic powder melts the plurality of ceramic particles;
- and
- setting at least a portion of the second layer of ceramic powder over the first ceramic layer, wherein setting the portion of the second layer forms a second ceramic layer having piezoelectric characteristics over the first ceramic layer.
An additively manufactured layered composite structure comprising:
- a first ceramic layer;
- wherein the first ceramic layer includes a ceramic powder having piezoelectric characteristics;
- and
- a second ceramic layer having a deposition configuration and a set configuration;
- wherein, in the deposition configuration a ceramic powder having piezoelectric characteristics is applied over the first ceramic layer as a powder layer;
- and
- wherein in the set configuration the ceramic powder is sintered over the first ceramic layer as a sintered layer.
A sonar device comprising:
- a piezoelectric transducer having an additively manufactured composite layered structure, comprising:
- a first ceramic layer having piezoelectric characteristics includes a deposition configuration and a set configuration:
- wherein in the deposition configuration a ceramic powder is applied over a build plate as a first powder layer;
- wherein in the set configuration the ceramic powder is sintered over the build plate as a first sintered layer;
- and
- a second ceramic layer having piezoelectric characteristics built over the first ceramic layer, the second ceramic layer includes a second deposition configuration and a second set configuration:
- wherein in the second deposition configuration the ceramic powder is applied over the first sintered layer as a second powder layer;
- wherein in the set configuration the ceramic powder is sintered over the first sintered layer as a second sintered layer;
- wherein at least one of the first ceramic layer or the second ceramic layer includes piezoelectric characteristics.
