We first developed a unique crystallographic lamellar microstructure (CLM), in which two differently oriented grains appear alternately, in a 316L stainless steel specimen via selective laser melting technology. The CLM was composed of major < 011 > grains and minor < 001 > grains aligned along the build direction, which stemmed from vertical and approximately +/- 45 degrees inclined columnar cells formed in the central and side parts of melt-pools, respectively. The development of CLM was found to largely improve the material properties via the strengthening of the product, simultaneously showing superior corrosion resistance to commercially obtained specimens.
