In this preliminary investigation of selective laser melting (SLM) of EH36 high tensile strength steel, a 175 W Yb:YAG laser in continuous wave mode was used to produce EH36 test specimens. The laser beam profile follows the Gaussian distribution and has a wavelength of 1.064 nm, with a focaldiamete...
