Abstract
An additive manufacturing system includes an extruder that includes a drive mechanism, a nozzle, and a pressure sensor. The drive mechanism is configured to feed a molten consumable material. The nozzle is attached at a distal end of the extruder and includes a nozzle tip, through which the molten consumable material is discharged as an extrudate. A pressure interface is fluidically coupled to an interior cavity of the nozzle. The pressure sensor is configured to operably measure a pressure within the interior cavity of the nozzle through the pressure interface.
