TL;DR: In this paper, a comparative study of selective laser melting (SLM) and electron beam melting (EBM) is presented for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds.

TL;DR: In this paper, the Inconel 718 cylinders were fabricated by selective laser melting in either argon or nitrogen gas from a pre-alloyed powder, and they exhibited columnar grains and arrays of oblate ellipsoidal precipitates oriented in a strong [2.0.0] texture determined by combined optical metallography, transmission electron microscopy, and X-ray diffraction analysis.

TL;DR: In this paper, a review of additive manufacturing technologies for the fabrication of unusual and complex metal and alloy products by laser and electron beam melting is presented using 3D optical and transmission electron microscope image compositions representing examples of 3D materials science.

TL;DR: In this paper, the authors examined 17-4 PH stainless steel powders produced by atomization in either argon or nitrogen atmospheres and correspondingly fabricated by selective laser melting (SLM) in either a nitrogen or argon atmosphere.
