摘要： A nozzle assembly for a printer head of a 3D printer includes a guide held in a fixed position relative to the printer head and extending from a first end to a second end along a longitudinal axis. A drive mechanism extends from a feed end to a discharge end along the longitudinal axis. The feed end defines a feed opening for receiving a filament from a feed system, and the discharge end defines a discharge opening for discharging the filament from the nozzle assembly. The drive mechanism is movable relative to the guide, and the drive mechanism includes a drive surface for engaging the filament and causing the filament to move from the feed opening to the discharge opening, in response to the drive mechanism moving relative to the printer head. The nozzle assembly further includes a motor for moving the drive mechanism relative to the printer head.

摘要： A nozzle is configured for receiving and dispensing a 3D printer filament. The nozzle includes a barrel, a heating element, and an end tip. The barrel has an internal bore and an exterior surface. The internal bore has a filament receiving end and a filament discharge end. A heat break is defined in the exterior surface of the barrel. The heating element is proximate the filament discharge end. The heating element includes a heating wire wrapped around the exterior surface of the barrel. The end tip is proximate the filament discharge end. The 3D filament is received in the filament receiving end heated by the heating element and dispensed through end tip proximate the filament discharge end.

摘要： A method of manufacturing a polymer coated cellulose nanocrystal composite material begins with an aqueous cellulose nanocrystal (CNC) suspension mixture. The aqueous CNC suspension mixture is dried to remove the liquid solvent from the aqueous CNC suspension mixture to form a dry CNC powder. Diethylenetriamine (DETA) is combined with melted Maleated-anhydride Polypropylene (MAPP) to form a DETA-functionalized MAPP (MA) mixture. The MA mixture is cooled and pelletized to form MA pellets. The MA pellets, the dry CNC powder, and a neat polypropylene (PP) are combined to form a CNC-PP mixture. The CNC-PP mixture is compounded by melting, subsequently cooled and pelletized to form CNC-PP pellets.

摘要： A mold assembly for use in manufacturing parts includes a first and second mold halves and a mold temperature control system. The first mold half comprises at least a first mold cavity and a first coolant passage. The second mold half comprising at least a second mold cavity and a second coolant passage. The mold temperature control system is in fluid communication with the first and second coolant passages of the first and second mold half. The mold temperature control system comprises a fluid, a means to control the temperature of the fluid, and a pump to circulate the fluid through the mold temperature control system and the first and second coolant passages.

摘要： A three-dimensional printer includes an enclosure defining a chamber and a print surface disposed within the chamber. The printer further includes a nozzle displaceable relative to the print surface for melting and dispensing a filament on the print surface to form a dielectric part during a printing process. The printer further includes a filament drive system for supplying the filament to the nozzle, and one or more capacitance sensors coupled to the print surface. The printer further includes a controller electrically coupled to the capacitance sensors for measuring a capacitance, with the controller generating an error signal in response to the controller determining a change of capacitance when the dielectric part is displaced relative to the print surface during the printing process. The printer further includes a display device electrically coupled to the controller and displaying an error message in response to the display device receiving the error signal.
