Abstract Scope |
Defects’ formation in parts produced by Laser Powder Bed Fusion (L-PBF) is one of the biggest challenges facing the wider adoption of additive manufacturing. Extensive research effort is invested in optimising the process parameters to produce defect-free parts. These studies primarily optimise the process parameters for a fixed size sample. Recent studies on Ti- and Ni-alloys have shown that an optimised set of process parameters might not be as effective if the sample size changes beyond a specific range. Not only does the content of defects change with the sample size but also the microstructure and mechanical properties. Therefore, in this study we investigate the correlation between the samples’ sizes and an ‘optimised’ set of process parameters in the case of L-PBF of AlSi10Mg alloy, evaluating the effect on the microstructure and mechanical properties. |
