    摘要： A device (1) for cleaning an extruder (2) of an FFF system is described comprising an extruder mount, a filament feeder, a detection unit arranged to detect extrusion of material out of the extruder, an inspection unit to visually inspect a portion of the filament. A controller is arranged to control a heating element of the extruder and to control the filament feeder and to receive measurement data from the detection unit. If the measurement data indicates that material is not extruded out of the extruder, the filament is retracted from the extruder at a purging temperature. Otherwise, the hot-end of the extruder is cooled off to a second temperature and then the filament is retracted from the extruder. The inspection unit will then perform a visual inspection of the tip portion of the filament. If the tip portion is not yet clean, the automated cleaning procedure is repeated.

    摘要： An extrusion device comprises a tubular body (2) which internally defines an extrusion duct, a worm screw (3) inserted in the extrusion duct and a containment body (4) suitable to contain a material to be extruded. The containment body (4) is configured to rotate around a rotation axis inclined with respect to a main development axis of the tubular body (2).

    摘要： A modular extrusion system for forming an article includes a support frame and a plurality of print head modules removably connected to the support frame. Each of the print head modules includes a printer head, a printer nozzle, a hopper, and an integrated control module. The hoppers are configured for holding a plurality of polymer pellets. The printer heads of the plurality of print head modules each include a body defining a barrel, a rotating extrusion screw extending through the barrel, and one or more heaters at least partially surrounding the barrel for melting the plurality of polymer pellets into a polymer resin formulation. The printer nozzles are configured for printing and depositing the polymer resin formulation onto a substrate to form the article. The modular extrusion system also includes a control system communicatively coupled to each of the integrated control modules for controlling the modular extrusion system.
