    Post-processing system for solid freeform fabrication parts
    WO 2009140449 A3
    Abstract
    A post processing system (10) is provided for cleaning and/or curing a part produced by solid freeform fabrication (SFF). The post-processing systems include a housing (12), a part retaining device to retain the part within the housing, and an actinic radiation source (22) 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.
