  • Publication number: 20170341897
    Abstract: Some examples of a document scanning system can include a scanner and a sheet output stacker. The stacker includes an upper surface configured to mate with the scanner configured to scan and transfer contents of a paper document. The stacker is configured to receive paper sheets from the scanner. The stacker includes multiple, upward extending interface housings positioned on the upper surface. The multiple interface housings are configured to be received in respective multiple receiving structures in the scanner, and are configured to mechanically and electrically couple the sheet output stacker and the scanner. The interface housings allow care-free electrical and mechanical pairing of a scanner to a stacker with no tools or adjustments. Simply positioning the scanner on the stacker such that the interface housings are aligned with the receiving structures results in the scanner being automatically guided into place and connected to the stacker through gravity.

  • Publication number: 20070063372
    Abstract: 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 removable 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.

  • Publication number: 20060071367
    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.

  • Publication number: 20050234577
    Abstract: A scheduling system or method with an interface that can provide a queue-list view and a calendar view. In the scheduling of a particular job on a particular machine, characteristics relating to the particular job (“job characteristics”) and characteristics relating to the particular machine (“machine characteristics”) can be taken into consideration by the scheduling system.

  • Publication number: 20050029175
    Abstract: A system for separating materials of differing melting points includes an ultrasonic bath with a solution configured to remove a meltable material by cavitation, and an emulsifier disposed in the solution, wherein the emulsifier is configured to solubilize the meltable material thereby extending a useable life of the solution.

  • Publication number: 20050033478
    Abstract: A closed loop system for separating materials of differing melting points includes an ultrasonic bath including a solution configured to supply thermal energy and cavitation to the materials of differing melting points, a solution reservoir configured to adjust levels of the solution in the ultrasonic bath, and a filter configured to remove particles of one of the materials of differing melting points from the solution.

  • Publication number: 20050023719
    Abstract: The present invention is drawn to a solid freeform fabrication system for producing a three-dimensional object. The system can include a dispensing system and a curing system. The dispensing system can be adapted to separately dispense build material and support material, wherein the build material and the support material are adapted to contact one another at an interface after being dispensed. The curing system can be adapted to harden the build material after being dispensed but before the support material is dispensed, wherein mixing between the build material and the support material is inhibited at the interface.
