Spatial variation of melt pool geometry, peak temperature and solidification parameters during laser assisted additive manufacturing process
A three-dimensional heat transfer and material flow model is developed to numerically
simulate the temperature and velocity fields in a laser assisted layer by layer deposition
process with coaxially fed powder particles. The computed results are tested with
independently reported temperature and build geometry for the deposition of multilayered
structures of austenitic stainless steel. The results provide detailed insight about the
important physical processes and show that the model can be used to understand the effects …

A three-dimensional heat transfer and material flow model is developed to numerically simulate the temperature and velocity fields in a laser assisted layer by layer deposition process with coaxially fed powder particles. The computed results are tested with independently reported temperature and build geometry for the deposition of multilayered structures of austenitic stainless steel. The results provide detailed insight about the important physical processes and show that the model can be used to understand the effects of process parameters on the thermal cycles, build geometry, cooling rates and solidification parameters in a multilayer additive manufacturing process.
