N2 - The mechanical properties of additive manufactured laser powder-bed fusion (L-PBF) AlSi10Mg specimens, built with the chessboard building strategy and followed by three thermal treatments, were evaluated using standard mechanical testing in tension. Metallography and fractography tests were conducted to reveal the microstructure and connect them to the properties in various stages of the research. A strong relationship between hatching strategy, build direction and loading direction was found and it was concluded that the mechanical properties of the alloy in the modified T5 (200oC) thermal condition are similar to the as-built condition for the concept strategy. The mechanical properties are similar albeit the differences found in the fracture faces of X and Z specimens. The similarity of the mechanical properties in the X and Z directions also suggests that the additively manufacturing (AM) L-PBF process yields fairly homogenous mechanical properties of AlSi10Mg (excluding the T5 treated alloy).
