Abstract

This paper presents an axially stacked coil structure for use in heating metal powders used in additive manufacturing. This structure acts as a quarter wavelength transmission line resonator providing H field hot spots evenly distributed across the structure. Using COMSOL Multiphysics and bench top measurements, these resonant modes and peak H fields are identified then used to efficiently heat 200cm3 of Ti-6Al-4V nowder to 100°C.
