    Abstract: A three-dimensional part printed using an additive manufacturing technique, which includes sets of printed cell layers, each defining an array of hollow cells with wall segments, and sets of printed transition layers, each being disposed between adjacent printed cell layers, where the sets of printed transition layers each comprise sloped walls that diverge from a first portion of the wall segments and that converge towards a second portion of the wall segments to interconnect the hollow cells of adjacent printed cell layers, and where the sloped walls of adjacent printed transition layers have printing orientations that are rotated from each other in a build plane.

    Abstract: A method for printing a three-dimensional part with an additive manufacturing system, the method including printing layers of the three-dimensional part and of a support structure for the three-dimensional part from multiple print heads or deposition lines, and switching the print heads or deposition line between stand-by modes and operating modes in-between the printing of the layers of the three-dimensional part and the support structure. The method also includes performing a purge operation for each print head or deposition line switched to the operating mode, where the purge operation includes printing a layer of at least one purge tower from the print head or deposition line switched to the operating mode.

    Abstract: A filament cassette and a filament loading assembly supply modeling filament to a liquifier in a three-dimensional deposition modeling machine. Two or more cassettes containing spooled filament are inserted into the machine. A strand of filament from a first one of the cassettes is fed to the liquifier for extrusion. Without operator intervention, the filament strand from the first cassette is withdrawn from the liquifier, and a filament strand from a second one of the cassettes is fed to the liquifier. The switching of filament feed sources is triggered by an event, such as an identification that the filament from the first cassette has reached a predetermined minimum length. In this manner, a used primary filament cassette is automatically replaced with a standby filament cassette, so that the machine need not experience downtime waiting for an operator to change the cassettes.
