Laser powder bed fusion provides freedom for producing complex shapes from a variety of
alloys. Moreover, it also gives the possibility to manipulate the chemical composition of …

In this paper, the capability of laser powder bed fusion (L-PBF) systems to process stainless
steel alloys is reviewed. Several classes of stainless steels are analyzed (ie, austenitic …

One of the most common additive manufacturing techniques for fabricating metallic
components is laser powder bed fusion, which has demonstrated great potential in …

Nitrogen is used as an alloying element, substituting the expensive and allergenic element
nickel, in austenitic stainless steels to improve their mechanical properties and corrosion …

Abstract Niobium (Nb) and molybdenum (Mo) are conventionally added to stainless steels to
improve their mechanical and corrosion properties. However, the effects of Nb and Mo …

Résumé Bien que la fusion laser sur lit de poudre (LPBF) soit le procédé de fabrication
additive le plus abouti aujourd'hui, peu de pièces industrielles sont fabriquées avec ce …

In this paper we report about the possibility to process stainless steels by laser powder bed
fusion (L-PBF) systems. Austenitic stainless steels are analysed showing the possibility to …

Abstract In Laser Powder Bed Fusion (L-PBF) of metallic materials, costs and material yield
strongly depend on the ability to reuse powder efficiently, as a significant amount is not …

The role of the inert gas during laser powder bed fusion (L-PBF) is to remove the process by-
products and the air that is initially present in the process chamber. On this purpose, different …

The development of the laser powder bed fusion (L-PBF) process to increase its robustness
and productivity is challenged by ambitious design optimizations, such as thin wall …
