ABSTRACT:
An apparatus and method of dispensing small-scale powders for a variety of applications, including, for example, fabricating a three-dimensional heterogeneous small-scale device, includes using a feed mechanism that causes motion of the powder particles and the steps of depositing fine heterogeneous materials (such as dry powders and biological materials) towards a substrate. The depositing step preferably includes providing a feed mechanism having an input to receive the material, an output, and a source of ultrasonic vibration to impart a torsional force on the material so as to precisely discharge the material from the output. To improve particle flowability, a cooling system is provided to cool the source, generally above a threshold input voltage.
