Abstract

See full text

A three-dimensional (3D) printer includes an acoustophoresis device having at least a first inlet, a first outlet, and a channel defined between the first inlet and the first outlet. A piezoelectric device is adhered to a surface of the acoustophoresis device to generate sound waves within the channel. A printhead is connected to the first outlet of the acoustophoresis device, wherein a solution comprising anisotropic particles is delivered to the at least first inlet and wherein the anisotropic particles are organized into one or more columns along an axis parallel to a direction of flow of the solution by standing acoustic waves generated by the piezoelectric device, wherein the at least one column of anisotropic particles is aligned with the first outlet, and wherein the first outlet is in fluid communication with the printhead to deliver one or more columns of ordered, anisotropic particles to the printhead.
