Abstract: A solid imaging method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.

Abstract: A UV curable composition useful for three-dimensional inkjet printing comprising (i) at least one UV curable urethane (meth)acrylate resin; (ii) at least one wax; (iii) at least one (meth)acrylate diluent; (iv) at least one photoinitiator; and (v) at least one polymerization inhibitor; wherein the amount of wax (ii) is sufficient to phase change the UV curable composition after jetting.

Abstract: An illumination system includes optics capable of adjusting the size of a beam of light and adjusting the focus of the beam of light. Spot size control optics adjusts the overall size of the beam of light and separately adjusts the ellipticity of the beam, primarily in one dimension. Light from the spot size control optics passes to focus control optics that control the overall focus of the beam of light and adjust the astigmatism of the beam by altering the focus position of the beam of light in one dimension. The laser system, the spot size control optics and the focus control optics are within an enclosure. Actuators under remote control from outside of the enclosure adjust both of the spot size control optics and focus control optics in the thermal environment of the illumination system.

Abstract: A component to control the viscosity of phase change material formulations is made by reacting selected nucleophiles, including fatty acid/alcohol reactants with an isocyanate, is disclosed. The addition of the isocyanate and the different nucleophiles will create a viscosity modifying component of low viscosity that can be formulated with higher molecular weight polyamide resins to achieve increased toughness in phase change solid imaging materials and carrier compositions used to make phase change ink jet inks.

Abstract: A method of manufacturing a part involving steps of using data derived from a slicing programme to control a manufacturing means that makes coatings that are the cross sectional slices of the required part which also contain right angles or some other edge feature that is the male or female counterpart to a feature made by a base, and, placing the coatings in the base and vibrating them, so that they settle in register onto the base's feature. In addition it is necessary the coating may be bonded together when they have been registered or as each coating is registered.
