Abstract: A solid freeform fabrication system includes a powdered build material deposited as a layer in a fabrication bin; a binding powder deposited as a layer over the layer of powdered build material; and an activating fluid that is selectively dispensed from an ejection head to activate the binding powder. The activated binding powder then selectively binds the build material into a cross-section of an object being fabricated.

Abstract: A method of dispensing a single ligament of fluid includes ejecting a first quantity of fluid from an inkjet dispenser toward a substrate, and ejecting a second quantity of fluid from the inkjet dispenser toward the substrate, wherein the second quantity of fluid is ejected from the inkjet dispenser at a frequency sufficient that the second quantity of fluid catches the first quantity of fluid thereby forming a single ligament of fluid prior to contacting the substrate.

Abstract: Materials and methods for freeform fabrication of a solid three-dimensional object are provided. At least one layer of support material and at least one layer of build material are dispensed onto a substrate. The support material includes at least one of water and a fusible water-containing substance and the build material is a substance other than water or a fusible, water-containing substance. After solidification, the at least one layer of support material is removed by an automated or manual process which includes washing with water at ambient temperature and/or causing the support material to undergo a phase change, to produce the solid three-dimensional object.

Abstract: A method for configuring and evaluating documents is described. A printing device accesses data that describes a document which includes one or more user designation areas. The printing device prints a first version of a document with user designation areas. The user completes the user designation areas and the printing device determines which user designation areas have been completed. The printing device accesses data from the computer where printed information is generated based on the completed users designated areas.

Abstract: A printer that includes a multi-colorant print cartridge is described. The printer can determine if a level of a most depleted colorant in the multi-colorant cartridge and a level of a least depleted colorant in the multi-colorant cartridge meet predetermined criteria. The printer can, if the criteria are met, perform a default printing procedure to print the document. The printer can, if the criteria are not met, perform an alternative printing procedure to print the document. The alternative printing procedure uses more of the least depleted colorant to print the document as compared to the default printing procedure.

Abstract: Embodiments of a method and/or system for material deposition for layers that include repetitive features are disclosed.

Abstract: Embodiments of a method and/or system for material deposition are disclosed.

Abstract: A three-dimensional object is fabricated from powder. A powder layer is deposited. The powder layer is selectively wetted to hinder movement of the powder. A binder is applied to selected areas of the powder layer to harden the areas of the powder layer. The steps are repeated until the three-dimensional object is fabricated.

Abstract: Methods and apparatuses for forming components or circuits by ejecting a fluid including materials in a single ligament are disclosed.

Abstract: Systems and methods for producing three-dimensional objects are provided. One exemplary system, among others, includes a layer forming system.
