Viscous pump for the extrusion-type deposition system

Pump system (10) includes a configured transport assembly to deliver solid material by the power of the first drive motor (16) (22), a screw pump (24), the barrel of the screw pump (10) a housing (84) at least partially defining the (106), the first end portion extruding end portion fixed to the housing (84) in the barrel (106) and (82), fixed to the housing (84), liquefier intersecting the barrel (106) and (85,342), and a screw pump (24) having an impeller (94) at least partially inserted through the barrel (106). Liquefier (85,342) accepts a solid material which is transmitted from the transfer assembly (22), the acceptance solid material at least partially melts, at least partially melted material in the barrel (106) is configured so as to move the impeller (94), by the power of the second drive motor (18), barrel tip-at least partially melted material is moved to (106) (82) It is configured so as to promote towards the.
