Abstract Scope Additive manufacturing of refractory metals, e.g., tungsten, presents new challenges to achieving quality components. In this work, a finite element model is presented to help design the manufacturing process. The model simulates the laser heating phenomenon in refractory metal 3D printing process. The laser beam shape follows a Gaussian profile. The powder bed is simplified as a porous media with porosity dependent properties. The effects of laser power and scan speeds on melt pool shape and associated temperature fields are studied. The simulation results are compared against the literature data.
