Claim:
A disposable liquid feed material cartridge for use in an apparatus for forming a three-dimensional object layer-by-layer by solid imaging comprising in combination: a. a housing having a top, a bottom, a first side and an opposing second side; b. a solidifiable liquid build material supply reservoir within the housing; c. a dispensing opening in the first side in fluid flow communication with the solidifiable liquid build material supply reservoir effective to feed liquid build material out of the feed material cartridge; d. a fluid flow control device effective to selectively control the flow of the solidifiable liquid build material from the solidifiable liquid build material supply reservoir to the dispensing opening; e. a scraper adjacent the top of the housing and the first side effective to collect unused liquid build material from a radiation transparent flexible build material carrier film and direct the unused liquid build material into the liquid feed material cartridge; and f. a collection reservoir adjacent the scraper to receive the unused liquid build material that is directed into the liquid feed material cartridge.
