CONTROLLED ENVIRONMENT FOR ADDITIVE MANUFACTURING

Abstract:

A controlled environment system for the additive manufacture of metal objects using magnetohydrodynamic jetting. A sealing plate is placed against an Peclet gap seal of a volume enclosure. A flow of inert gas is used to maintain a high-purity volume in the interior of the volume enclosure. A print head accesses the interior and delivers build material through a hole in the sealing plate. A build plate is movable relative to the sealing plate within the interior of the volume enclosure on which objects can be fabricated.
