Abstract: Disclosed herein are systems and methods for using printing process data to predict quality measures for three-dimensional (3D) printed objects and properties of the materials comprising the 3D objects. Printing may be performed using resistive or Joule printing. The system may include a computer communicatively coupled to a 3D printing apparatus, which may store printing parameters. The 3D printing apparatus may be able to take measurements during a print job, and record those measurements in memory. The 3D printing apparatus may also be able to record printing states before, during, and/or after printing. A combination of printing states, printing parameters, and measurements may be analyzed, for example, by a machine learning algorithm, in order to predict material properties and quality measures.

Abstract: The present disclosure provides a system for feeding a wire. The system may comprise a wire source configured to hold a wire. The system may comprise a driver roller configured to undergo rotation to direct the wire towards a wire receiver. The system may comprise a preload roller adjacent to the driver roller and configured to come in contact with the wire at a position adjacent to the driver roller. The preload roller and the driver roller may be separated by a gap. The size of the gap may be adjustable to permit the wire to be directed through the gap. The system may comprise an actuator coupled to the driver roller or the preload roller and configured to adjust the size of the gap. The system may comprise a controller operatively coupled to the actuator. The size of the gap may be adjusted by real-time closed-loop feedback.

Abstract: The present disclosure provides a method for printing a three-dimensional object, comprising calculating at least one deposition parameter based on a computational representation of the 3D object, and using a print head to initiate printing in accordance with the deposition parameter. The printing comprises subjecting at least one feedstock to heating upon flow of electrical current through the feedstock and into the base, or vice versa. Next, (i) one or more properties of the 3D object or feedstock may be measured and (ii) whether the one or more properties of the 3D object measured in (i) meet one or more predetermined properties of the 3D object or the feedstock may be determined. The deposition parameter may be adjusted upon determining that the properties measured do not meet the predetermined properties. The print head and the adjusted deposition parameter may be used to continue to print the 3D object.
