摘要:
Apparatus to capture aerosols, fluid jetting apparatus, and aerosol diverters are disclosed. An example aerosol capture apparatus includes a corona wire to generate ions, and a reference plate positioned below the corona wire and above a substrate on which a fluid is to be deposited, the reference plate to provide a reference potential to direct the ions toward the reference plate to force aerosol particles associated with the fluid toward the reference plate.

Systems and methods for producing three-dimensional objects are provided. One exemplary system, among others, includes a layer forming system. The layer forming system is operative to implement criteria for forming the three-dimensional object. The three-dimensional object includes a plurality of layers and each layer includes layers selected from a shell layer and an interior layer. The shell layer includes at least one shell voxel, and the interior layer includes at least one interior voxel. In addition, the layer forming system is operative to form the layers in an iterative manner according to the criteria, plane at least one layer in a manner according to the criteria, control waste produced by controlling the formation of the layers using the criteria provided, and form the object.

A method of producing an object through solid freeform fabrication includes selectively depositing a boundary structure that defines a surface of the object, and depositing a flowable build material within the boundary structure, wherein the flowable build material forms a portion of the object by flowing to the boundary structure.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
Solid freeform fabrication systems, powder supply bins for solid freeform fabrication systems, and methods of solid freeform fabrication are disclosed. One exemplary solid freeform fabrication system includes a powder supply bin, a build bin, a roller, and a print head disposed above the build bin that deposits a binder onto the powder in the build bin in a preselected pattern, the supply bin and/or the build bin translating in a x- and/or y-direction relative to the print head.
摘要:
The present invention is drawn to solid freeform fabrication systems and methods for producing three-dimensional objects. The system can include build material configured to be deposited in layers to form a three-dimensional object; and support material configured to be deposited adjacent to the build material for supporting the build material during formation of the three-dimensional object. The support material can also be configured to form a feature that imparts a predetermined property within the three-dimensional object.
