Abstract: 3-D printing transfers build material and support from an intermediate transfer belt (ITB) to a platen. The build material is the same as the support material, except that the build material includes a photoinitiator and the support material does not. The platen moves to make contact with the ITB, and the ITB transfers successive layers of build material and support material each time the platen contacts the ITB. The platen and a portion of the ITB that is adjacent the platen are heated prior to the platen contacting the ITB, and the same is exposed so as to crosslink polymers of build material, without crosslinking polymers of support material. The polymers of build material being crosslinked and the polymers of support material not being crosslinked makes the support material selectively soluble in a solvent.

Abstract: A method is disclosed. For example, the method includes printing an image on a substrate, applying an adhesive on select portions of the image, coupling the image to a wave guide such that the adhesive contacts a surface of the wave guide, and providing a light through the wave guide such that the light is emitted through the wave guide and the adhesive and the light is reflected by the select portions of the image back through the adhesive and the wave guide.

Abstract: A support material toner particle for use in xerographic additive manufacturing includes a PVA polymer blend including a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer blend to be within about 1° C. to about 20° C. of a desired build material toner Tg. A xerographic toner system includes a build toner material and a support toner material, the support toner material includes a PVA polymer blend including a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer blend to be within about 1° C. to about 20° C. of the build material toner Tg. A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.

Abstract: A three-dimensional object printer generates image data of an object being formed in the printer with an optical sensor and identifies the heights of object features above a substrate on which the object is being formed. A controller operates one or more actuators to move the optical sensor at a plurality of distances above the object to generate image data of the object at a plurality of heights above the object. The controller identifies the distances of the features of the object with reference to the image data generated by the optical sensor and the focal length of the optical sensor.

Abstract: A 3-D printer includes a development station positioned to electrostatically transfer layers of material to an intermediate transfer surface, and a transfuse station adjacent the intermediate transfer surface. The transfuse station is positioned to receive the layers as the intermediate transfer surface moves past the transfuse station. Also, a platen is included that moves relative to the intermediate transfer surface. The intermediate transfer surface transfers a layer of the material to the platen each time the platen contacts one of the layers on the intermediate transfer surface at the transfuse station to successively form a freestanding stack of the layers on the platen. A curing station is positioned to apply ultraviolet light to each layer, after each layer is transferred from the transfuse station to the platen. The curing station selectively applies the ultraviolet light to crosslink polymers only in a portion of the material within the layer.
