Title: BAFFLE DOORS FOR ADDITIVE MANUFACTURING SYSTEM
Abstract:
An additive manufacturing system (140) for printing three-dimensional parts (148), the system (140) including a build chamber (142) having an opening (143) with first and second opposing edges (131, 133), and a platen (132) in the build chamber (142). A baffle door (120) expandable across the opening (143) has a first baffle section (121) attached at the first opposing edge (131) and configured to extend between a first position adjacent the first opposing edge and a second position adjacent the second opposing edge (133), a second baffle section (122) attached at the second opposing edge (133) and configured to extend between a first position adjacent the second opposing edge (133) and a second position adjacent the first opposing edge (131), and a third baffle section (123) having a frame (125), a tool port (124) in the frame (125), and baffles on either side of the tool port (124), the baffles configured to expand and contract in a second direction substantially perpendicular to the first direction as the tool port (124) moves within the frame (125). The baffle door (120) insulates the build chamber (142). User access to the build chamber (142) is enabled by opening and closing the baffle door (120).
