Abstract: A pump system (10) comprising a delivery assembly (22) configured to feed a solid material under operational power of a first drive motor (16), and a screw pump (24) comprising a housing (84) that at least partially defines a barrel (106) of the screw pump (10), an extrusion tip (82) secured to the housing (84) at a first end of the barrel (106), a liquefier (85, 342) secured to the housing (84) and intersecting with the barrel (106), and an impeller (94) extending at least partially through the barrel (106). The liquefier (85, 342) is configured to receive the solid material fed from the delivery assembly (22), to at least partially melt the received solid material, and to direct the at least partially melted material to the barrel (106), and the impeller (94) is configured to drive the at least partially melted material that is directed to the barrel (106) toward the extrusion tip (82) under operational power of a second drive motor (18).

Abstract: A modeling apparatus (10) includes a platform (14) and a substrate (16), which are adapted to be releasably locked together to provide a surface for building up models in an additive-process three-dimensional modeling machine (12). The substrate (16) comprises a substantially rigid, non-dusting tray (50) providing a modeling surface (52). Male connectors extending from the tray are seated in male connectors in the platform (14), to engage the substrate (16) to the platform (14). The engaged substrate (16) is locked to the platform (14), maintaining accurate positioning of the substrate (16) while a model is built. After modeling is complete, the substrate (16) is released from the platform (14), the model is removed, and the substrate may be reused.
