System and method for additive manufacturing for deposition of metal and ceramic materials

摘要

The present disclosure relates to additive manufacturing systems and methods for reducing or eliminating defects in bulk deposit material microstructures resulting from additive manufacturing processes. The additive manufacturing system includes evaporating the deposit material to form the evaporated deposit material and ionizing the vaporized deposit material to form an ionized deposit material flux. After forming the ionized deposition material flux, the ionized deposition material flux is guided through the aperture, accelerated to a controlled kinetic energy level, and deposited on the surface of the substrate. The aperture mechanism may include a physical, electrical or magnetic aperture mechanism. The evaporation of the sediment material can be performed by an evaporation mechanism consisting of resistance heating, induction heating, thermal radiation, electronic heating, and electric arc source heating.
