A disposable liquid build material feed cartridge for use in a solid imaging apparatus and a method of dispensing build material for use in such an apparatus with a radiation transparent build material carrier. The disposable liquid build material feed cartridge recovers unused liquid material from the radiation transparent build material carrier and recycles it through a filter into a supply reservoir for reuse. A dispersing roller is employed to express any entrapping air bubbles in the solidifiable liquid build material that is dispensed onto the radiation transparent build material carrier prior to its being imaged.
