1. A three-dimensional (3D) printing method, the method comprising:
applying a solution having a plurality of anisotropic particles suspended in the solution to a channel, wherein the channel is connected to a printhead outlet and a waste outlet;
applying acoustic waves to the channel, wherein a frequency of the acoustic waves is selected to organize the plurality of anisotropic particles into one or more columns of organized anisotropic particles; and
depositing the solution comprising the one or more columns of the organized anisotropic particles onto a substrate via the printhead outlet.
