Abstract: An apparatus includes a precursor dispenser for dispensing a precursor material into a workspace, one or more acoustic sources configured to direct acoustic waves towards the workspace to provide acoustic fields that arrange the precursor material in a three-dimensional shape in the workspace, one or more sensors configured to detect a distribution of the precursor material in the workspace, and an electronic controller in communication with the precursor dispenser, the one or more acoustic sources, and the one or more sensors, the electronic controller being programmed to cause the one or more acoustic sources to adjust the acoustic fields to reduce deviations in the distribution of the precursor material from the three-dimensional shape in the workspace.

Abstract: An apparatus includes an acoustic source for directing an acoustic wave towards a workspace, a variable acoustic diffractive device positioned in a path of the acoustic wave between the acoustic source and the workspace, the variable acoustic diffractive device including an array of elements each having independently variable acoustic properties, and an electronic controller in communication with the acoustic source and the variable acoustic diffractive device, the electronic controller programmed to supply signals to cause the acoustic source to produce the acoustic wave and the variable acoustic diffractive device to diffract the acoustic wave from the acoustic source to provide non-uniform acoustic forces in a medium located in the workspace.
