Abstract: Technologies for non-contact displacement control are disclosed. An additive manufacturing system may include a dispenser having a tip configured to deposit an additive material onto a substrate, a transducer coupled to the dispenser and configured to transmit an emitted signal from the dispenser to the substrate, and a sensor coupled to the dispenser and configured to detect a return signal from the substrate to the dispenser, where the return signal is indicative of a distance between the tip of the dispenser and the substrate.
