Abstract: In example implementations, an apparatus includes a housing, a movable base, a tab portion and a coupling mechanism. The housing is comprised of a microwave transparent material. The movable base is coupled to the housing to receive build material that is digitally printed. The tab portion is coupled to a bottom portion of at least one wall of the housing. The tab portion stops the movable base. The coupling mechanism is coupled to the housing to removably attach the apparatus to a three dimensional printer.
