Additive manufacturing with dynamic magnetic fields

Abstract

A method of and a three dimensional (3D) printing system for melting material into a melt pool and enabling a dynamic magnetic field to create a thermal electromagnetic force in the melt pool. The method and 3D printing system may depositor the material on a build plate and apply an energy beam to melt the material. The material may be deposited into a plurality of layers, where the melt pool may be within one or more of the plurality of layers and the energy beam may additionally form a liquid in the one or more of the plurality of layers such that the thermal electromagnetic force causes a fluid flow within the liquid and the melt pool. The method and 3D printing system may control the dynamic magnetic field across the build plate. The dynamic magnetic field may be generated by segmented and independent electromagnetic coils.
