    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a wire detector to determine a position of a top surface of melted metal contained in a receptacle of a heated vessel in the apparatus from time to time. The solid metal wire being fed into the heated vessel is retracted and the length of the retracted wire is determined using a signal generated by the wire detector. The determined length of the wire is used to identify the position of the top level of the melted metal in the receptacle so the receptacle can be replenished if the level has fallen below a predetermined capacity for the receptacle.

    Abstract: Systems for and methods of providing a feed rate for three-dimensional printing a part are presented. The disclosed techniques include: obtaining computer readable toolpath instructions for the part, where the toolpath instructions specify a nominal feed rate for a toolpath segment and spatial toolpath data of the toolpath segment; providing an input including the spatial toolpath data to a trained machine learning system, where the trained machine learning system has been trained using training data including: training spatial toolpath data, training closed loop gain data, and training feed rate data; obtaining a revised feed rate for the toolpath segment different from the nominal feed rate for the toolpath segment, where the revised feed rate is output from the trained machine learning system; and providing revised computer readable toolpath instructions, where the revised machine learning toolpath instructions include the revised feed rate.

    Abstract: The present disclosure provides a method of forming an overhang for a three-dimensional printed part. The method includes ejecting one or more drops of a print material to create a preform onto a top layer of a three-dimensional printed part where the preform is oriented at an angle of 60 degrees or greater relative to a print bed in a first dimension, and bending the preform to form the overhang having an angle of less than 90 degrees relative to the print bed, and where no portion of the preform contacts the print bed. A printing system for executing a method of forming an overhang for a three-dimensional printed part is also disclosed.
