Abstract
Provided herein are devices and systems for depositing a material or manufacturing a product, such as a pharmaceutical dosage form, by additive manufacturing. Further provided are methods of using the devices and systems, as well as methods of manufacturing a product, such as a pharmaceutical dosage form, by additive manufacturing. In certain embodiments, the device includes a material supply system configured to melt an pressurized a material, a pressure sensor configured to detect a pressure of the material within the device, and a control switch comprising a sealing needle operable in an open position and closed position. The sealing needle extends through a feed channel containing the material and includes a taper end, wherein the tapered end of the sealing needle engages a tapered inner surface of a nozzle to inhibit flow of the material through the nozzle when the sealing needle is in the closed position.
