Abstract: An additive manufacturing device includes at least one liquefier assembly that receives filament material from at least one feedstock and extrudes the material in a flowable form. A thermal drying system removes water vapor and heats compressed air to a preselected temperature set point to form conditioned air. At least one enclosed filament path houses and guides the filament material from a supply to the at least one liquefier assembly. The enclosed filament path is exposed to the conditioned air from the thermal drying system so as to keep the filament material dry as it is fed to the at least one liquefier assembly.

Abstract: Disclosed are three-dimensional parts, such as orthotics and prosthetics, having sinusoidal wave pattern infill structures first and second boundary walls. Also disclosed are printers or systems configured to manufacture such parts, as well as methods of manufacturing such parts. The sinusoidal wave pattern infill structures are formed between, and normal to, the first and second boundary walls and are configured to provide locally tunable structural properties in different regions of the part.

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.
