Martensitic precipitation hardenable stainless steels (PHSSs) are among the most studied materials for additive manufacturing (AM), but semi-austenitic PHSSs are much less explored. This work reports the AM of semi-austenitic PHSS 17-7PH samples using laser-powder bed fusion (L-PBF) and laser-directed energy deposition (L-DED) with different combinations of process parameters. The results show that for L-DED it was possible to obtain single tracks with good metallurgical bonding to the substrate and a nearly full austenitic microstructure. The samples manufactured by L-PBF with the optimal parameters showed densification above 99%, but with a predominantly ferritic matrix, which requires a solubilization heat treatment to archive the desired austenitic or martensitic microstructures.
