  • Publication number: 20180194056
    Abstract: A print bed levelling system for an additive manufacturing system includes a nozzle head assembly movably arranged with respect to a substantially flat print bed member, wherein the nozzle head assembly comprises one or more nozzle bodies, and a contactless sensor member disposed at a print bed engagement end of the nozzle head assembly. The contactless sensor member includes a sensing surface in sensing engagement with the print bed member over a relative sensing distance range between a distal sensing position and a proximal sensing position.

  • Publication number: 20170210033
    Abstract: A nozzle lifting assembly for an additive manufacturing system includes a base member and a lift member relatively movable with respect thereto, a first nozzle body arranged for being lifted by the lift member and a second nozzle body disposed on the base member. A wedge member is movably arranged relative to the base member and in wedging engagement with the lift member between a first and second wedge position, wherein the first and second wedge position correspond to a lowered position and a lifted position of the first nozzle body with respect to the second nozzle body, respectively.

  • Publication number: 20170094726
    Abstract: An inductive nozzle heating assembly for an additive manufacturing system, comprises a rod shaped nozzle body of electrically conductive material provided with a passageway extending from an inlet end to an outlet end of the rod shaped nozzle body for dispensing an extrudable material. An induction coil unit is provided for magnetic engagement with the rod shaped nozzle body to allow heating thereof, wherein the induction coil unit encloses at least in part the rod shaped nozzle body. The induction coil unit and rod shaped nozzle body are spaced apart and separated by a minimum distance (Lg) larger than zero, and the rod shaped nozzle body comprises a heating piece having a predetermined Curie temperature.
