Abstract Scope Laser powder bed fusion enables the design and manufacture of novel electromagnetic devices that cannot be realized through traditional processes. The objective of this research is to identify a range of processing conditions that produces acceptable mechanical and soft magnetic properties from iron alloyed with 3.5 weight percent silicon. The laser powder bed fusion (EOS M290) process has been mapped for laser powers from 100 W to 360 W and laser scanning velocities of 500 mm/s to 1500 mm/s. The highest density parts’ magnetic hysteresis and mechanical properties are measured in the as-built and heat treated condition. Densities up to 7556 kg/m3 and top side surface roughness down to Ra of 1.65 Ám are reported. Fe-3.5Si alloy was found to be an acceptable material feedstock for laser powder bed fusion with a wide range of laser powers and velocities that produced densities and surface roughness comparable to widely adopted materials.
