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: A three-dimensional (3D) metal object manufacturing apparatus is operated to compensate for surface deviations of overhanging features differently than for non-overhanging features. The compensation technique used for the overhanging features depends on whether an edge of the overhanging feature being formed in a next layer has curved or sharp corners.

Abstract: A method and apparatus that adjusts the step count at which a tray low paper condition is declared based on the number of outstanding feed commitments and the average number of feeds between tray increments. After a first tray increment has occurred, feeder software will wait a pre-determined number of additional tray increments, and will then calculate the average number of feeds between increments. Using this average and the number of outstanding feed commitments a low paper condition is declared when a predetermined logical test is true.
