摘要: An additive manufacturing system may include a carrier, a set of rails coupled to the carrier, and a transition housing movably attached to the set of rails. The additive manufacturing system may include an extruder having an extruder barrel coupled to the transition housing, and a melt pump fixedly attached to the carrier. The melt pump may be in fluid communication with the extruder barrel. Additionally, the additive manufacturing system may include a nozzle in fluid communication with the melt pump, and a roller rotatable about the nozzle.

摘要: An additive manufacturing apparatus includes a material container having a hollow interior configured to receive a material and an extruder connected below the material container to receive the material from the material container. The additive manufacturing apparatus includes a material removal device including an actuator configured to activate the material removal device to dislodge retained material from within the hollow interior of the material container and a drain passage configured to receive the dislodged material and guide the material to an exterior of the additive manufacturing apparatus.

摘要: A system for additive manufacturing includes a nozzle configured to translate along a first axis, a second axis perpendicular to the first axis, and a third axis orthogonal to the first and second axes, wherein the nozzle is operably coupled to: an extruder having an outlet and including a screw disposed within a barrel, and a pump having an inlet and an outlet. The inlet is coupled to the extruder, and the outlet is in fluid communication with the nozzle. The system also includes a controller configured to adjust a speed of the pump with respect to a speed of the screw to apply a target pressure at the outlet of the extruder.

摘要: An exemplary additive manufacturing system may include an extruder having an opening dimensioned to receive a material. The extruder also may have a barrel and a screw within the barrel. The screw may have a diameter ranging between about 20 mm and about 150 mm and the barrel extends along a longitudinal axis. The system may include one or more heaters positioned along at least a portion of the barrel. As the material passes through the barrel, the one or more heaters may at least partially melt the material. The system may further include a gear pump in fluid communication with the barrel for receiving the at least partially melted material. Additionally, the system may include a nozzle in fluid communication with the gear pump for depositing the at least partially melted material. The system also may include a vertical worktable.

摘要: A method for adjusting print speed during an additive manufacturing process may include receiving at an additive manufacturing machine, information including at least a current layer print speed. The method may further include determining a current layer print time based on at least the current layer print speed and adjusting the current layer print speed to an adjusted current layer print speed based on at least the current layer print time and a minimum layer cooling time. Further, the method may include printing a layer of a part at the adjusted current layer print speed.

摘要: Embodiments of the present disclosure are drawn to additive manufacturing methods. An exemplary method may include generating a tool path for forming a component via additive manufacturing, and assessing the tool path to identify a change in direction. The method may also include determining if the change in direction exceeds a predetermined angle, and adding a tangent arc to the tool path before the change in direction if the change in direction exceeds the predetermined angle.
