摘要:
A gantry assembly for use in an additive manufacturing system, the gantry assembly comprising a first bearing shaft, a carriage slidably engaged with the first bearing shaft, and a second bearing shaft operably supported by the carriage, the second linear bearing extending along a second axis. The gantry assembly also comprises a tool-head mount slidably engaged with the second linear bearing, a drive belt secured to the tool-head mount, a first motor having a first drive shaft engaged with the drive belt, and a second motor having a second drive shaft engaged with the drive belt.
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 support structure removal system comprising a vessel and a second component. The vessel comprises a vessel body, a porous floor configured to retain a three-dimensional part, and an impeller rotatably mounted below the porous floor. The second component comprises a surface configured to operably receive the vessel, and a rotation-inducing assembly located below the surface, where the rotation-inducing assembly is configured to rotate the impeller with magnetic fields when the vessel is received on the surface of the second component to agitate and direct flows of an aqueous fluid through the porous floor.
