    摘要： A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build. The invention also provides for tilting the build elevator to reduce air entrainment and for releasing the build from the image plane.

    摘要： A method and apparatus for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.

    摘要： A post-processing system is provided for cleaning and/or curing a part produced by solid freeform fabrication (SFF). The post-processing systems include a housing, a part retaining device to retain the part within the housing, and an actinic radiation source to cure the part with actinic radiation. The systems also include a fluid circulation device adapted to expose the part to cleaning fluid and/or to allow the cleaning fluid to absorb actinic radiation to permit filtration of removed build material to allow extended use of the cleaning fluid. Certain systems include a first rotating portion that can rotate the retained part about a first axis, and further systems include a second rotating portion that can rotate the retained part about a second axis. The systems also include additional features to provide safe and efficient cleaning and/or curing of parts produced by SFF.
