摘要： A spool assembly comprising a housing structure, a spool rotatably retained in an interior region of the housing structure, and a sealed sheath encasing the housing structure to define a barrier for the encased housing structure and the rotatably retained spool. The spool assembly further comprises a locking arm disposed outside of the sealed sheath and configured to operably engage the spool through the sealed sheath and through the housing structure in a manner that does not penetrate the sealed sheath, where the locking arm prevents the spool from rotating relative to the housing mechanism when operably engaged with the spool. The locking arm may disengage from the spool in a hands-free manner when the spool assembly is loaded into a bay of an additive manufacturing system.

摘要： A liquefier assembly for use in an additive manufacturing system to print three-dimensional parts, which includes an upstream pressure-generating stage and downstream flow-regulating stage. The upstream pressure-generating stage includes a drive mechanism, a liquefier configured to melt a consumable material receive from the drive mechanism to produce a molten material in a pressurized state. The downstream flow-regulating stage includes a gear assembly having a casing assembly and a pair of gears disposed within the interior cavity and engaged with each other to regulate a flow of the pressurized molten material through the gear assembly for controlled extrusion.
