Abstract: A filament for use in an extrusion-based additive manufacturing system includes an elastomeric core and a harder, non-elastomeric shell. The core compositionally comprising an elastomeric core material having a flexural modulus of less than 31,000 psi and a durameter of less than 80 Shore. The shell overlays the core portion and compositionally comprises a non-elastomeric thermoplastic shell material that is substantially miscible with the elastomeric core material, wherein the core material and the shell material have the same monomer chemistry. The non-elastomeric thermoplastic shell material has a flexural modulus that is greater than the flexural modulus of the elastomeric core material by at least a factor of five, wherein the shell provides sufficient strength or stiffness to the filament such that filament can be utilized as a feedstock in the extrusion-based additive manufacturing system.

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.

Abstract: An additive manufacturing system includes a gantry configured to move in a build plane. A platen is configured to support a part being built in a layer by layer process and wherein the platen is configured to move in a direction substantially normal to the build plane. A head carriage is carried by the gantry wherein the head carriage includes ferromagnetic material. The system includes at least one print head where the print head includes a housing and one or more magnets attached to the housing wherein the at least one print head is configured to be coupled to the head carriage through a magnetic coupling between the one or more magnets and the ferromagnetic material such that the print head is configured to move rotationally relative to the head carriage.
