Abstract: The present disclosure relates to an apparatus for extruding material to make a part using a flowable feedstock printing material. In one embodiment the apparatus makes use of a controller and a print nozzle system. The print nozzle system includes a nozzle housing for receiving the flowable feedstock material, and a nozzle element from which the flowable feedstock material is extruded. A valve system is included which communicates with the controller for controllably interrupting and restarting a flow of the flowable feed during a print operation.

Abstract: A method of manufacturing a physical object comprises, during a process of manufacturing the physical object by a machine, capturing image data of at least a portion of the physical object and other sensor data related to the machine or to the at least a portion of the physical object. The method further comprises, during the process of manufacturing the physical object, for each of the plurality of pixels of the image data, coregistering the image data with the other sensor data on a pixel-by-pixel basis, storing the coregistered image data and other sensor data in association with each other in a data structure, and using at least a portion of the coregistered image data and other sensor to detect an anomaly in the physical object or in the process of manufacturing the physical object.
