摘要:
A liquefier assembly for use in an extrusion-based additive manufacturing system, the liquefier assembly comprising a downstream portion having a first average inner cross-sectional area, and an upstream having a second average inner cross-sectional area that is less than the first inner cross-sectional area, the upstream portion defining a shoulder configured to restrict movement of a melt meniscus of a consumable material.
摘要:
A payout tube for enabling payout of a consumable filament from a consumable assembly that is configured for use with an additive manufacturing system, the payout tube comprising a tip end having an inlet opening, a base end having an outlet opening, and a tube body having an average effective outer diameter that is substantially greater than an effective inner diameter of the inlet opening.
摘要:
A print head assembly that includes a receptacle supported from a carriage frame and configured to receive a print head, and a toggle mechanism configured to move the receptacle relative to the carriage frame.
摘要:
A method for building a three-dimensional model with an extrusion-based additive manufacturing system having an extrusion head, the method comprising depositing a consumable material from a liquefier assembly at an extrusion rate to substantially normalize a meniscus height within the liquefier assembly.
摘要:
A print head assembly that includes a print head carriage and multiple, replaceable print heads that are configured to be removably retained in receptacles of the print head carriage. The print heads each include a cartridge assembly and a liquefier pump assembly retained by the cartridge assembly.
