Abstract: An additive manufacturing system includes a substantially moisture-impermeable barrier comprising a guide tube assembly for supplying filament from a filament supply to a print head in an extrusion-based additive manufacturing system, where the print head melts the filament and extrudes the melted filament to form a 3D part. The guide tube assembly includes an inner tube permeable to moisture and an outer tube that s substantially moisture impermeable. The inner tube has an interior passageway configured to receive the filament, and has a relatively low coefficient of friction to minimize drag force as the filament travels through it. The outer tube surrounds the inner tube and provides a substantially moisture-impermeable barrier around the inner tube.

Abstract: A method for additive manufacturing a part using fused deposition modeling 3D printing technology includes projecting a laser image from one or more laser emitters onto a previously printed bead or beads of thermoplastic material forming a portion of the part, along a tool path for a next bead in a subsequent part layer. The laser image has a width of between about 50% to 75% of a commanded beadwidth of the next bead, and is moved along a tool path that is generally transverse to the width thereof, to thereby selectively irradiate and heat the previously printed thermoplastic material to at least a bonding temperature thereof but below a degradation temperature. A bead of thermoplastic material is extruded from an extrusion head and deposited along the tool path while at least a top surface portion of the irradiated material remains at or above its bonding temperature, so that strong adhesion occurs between part layers.

Abstract: A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a matrix of a first base polymer and particles dispersed within the matrix, and a shell portion comprising a same or a different base polymer. The consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional part, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament and retain the particles within the roads of the printed part and do not penetrate the outer surface of the shell portion.

Abstract: A water dispersible sulfo-polyamide is configured as a filament for use as an extrudable support material in the additive manufacture of a part comprising a non water dispersible polymer. The water dispersible sulfo-polyamide is a reaction product of a sulfo monomer, the water dispersible sulfo-polymer being dispersible in water resulting in separation of the water dispersible polymer from the part comprising the non water dispersible polymer.

Abstract: An additive manufacturing system for forming 3D parts includes a platen, a gantry, at least one print head, and a retention device. The gantry is configured to move the platen along a vertical axis. The at least one print head is configured to extrude part and/or support material onto a sheet substrate that is positioned on a support surface of the platen. The retention device includes a frame that is configured to press two or more edge portions of the sheet substrate against the support surface of the platen when the retention device is in a lowered position relative to the platen or support surface.

Abstract: A consumable material for use in an extrusion-based digital manufacturing system, the consumable material comprising a length and a cross-sectional profile of at least a portion of the length that is axially asymmetric. The cross-sectional profile is configured to provide a response time with a non-cylindrical liquefier of the extrusion-based digital manufacturing system that is faster than a response time achievable with a cylindrical filament in a cylindrical liquefier for a same thermally limited, maximum volumetric flow rate.
