Direct metal writing is an additive manufacturing technique where semi-solid metal (SSM) slurries are deposited layer-by-layer. An oscillatory shear rheometer was used to confirm the shear thinning behavior of SSM slurries and develop a processing range for bismuth-tin. Computer simulations for the flow of SSM slurries through a nozzle demonstrated that precise thermal control at the nozzle’s tip was necessary to avoid clogging and large pressure drops, especially for nozzles with outlet diameters smaller than 300 microns. The collected data had applications for a physical DMW apparatus being tested at the Lawrence Livermore National Laboratory.
