Abstract: A vaporizer cartridge includes a non-conductive base that has a top end, a bottom end, and an exterior side surface. The exterior side surface is at least partially threaded to enable the bottom end to screw into a battery unit. The vaporizer cartridge also includes a body with a bottom end coupled to the top end of the non-conductive base. The body includes a cavity configured to store a vaporizable liquid. A vaporization chamber that is fluidly coupled to the cavity includes a heating element for heating liquid, causing it to vaporize. The heating element has first and second electrical ends that are electrically coupled to the terminals of a battery when the cartridge is screwed into the battery unit. The first and second ends of the heating element are coupled to the terminals by first and second connectors, respectively.

Abstract: A three-dimensional printing materials system and method can produce both appearance models and small numbers of functional parts in an office environment. The method can include building cross-sectional portions of a three-dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas can be built by using an ink-jet printhead to deliver an aqueous solvent or binder to an adhesive particulate mixture, causing the particles of the mixture to adhere together, and to previous cross-sectional areas. The binder can include at least one of nonaqueous organic monomeric compound, anionically ionizable polymer, cationic polymer, polymer, waterborne colloid, or inorganic solute.
