Processing parameter correlations in powder bed fusion additive manufacturing for Fe–Si soft magnetic materials through design of experiments

“…This study focused on an efficient and effective investigation of the correlation between process parameters, microstructure and magnetic properties of L-PBF samples using DoE. Among various DoE methodologies, the response surface methodology is an efficient way to estimate the interactions between factors and output results and optimise the process parameters using a limited amount of experimental data [16]. Figure 9 presents 3D response surface plots showing the relationship between process parameters (i.e.…”

“…A design of experiment (DoE) is a statistical methodology that can be applied for various purposes, including extracting major effective parameters, determining the effect of a single parameter, efficient experimental planning and optimising parameters. In particular, the combination of screening, experimental design and surface response using DoE can lay out the shortest route for investigating the effect of process parameters and optimal conditions [16,17]. However, despite these advantages, there has yet to be a report on the DoE to achieve the above purpose for high silicon-content Fe–Si alloys manufactured by the L-PBF process.…”
