Strong feature size dependence of tensile properties and its microstructural origin in selectively laser melted 316L stainless steel
TL;DR: In this article, the effect of feature size dependence on the mechanical properties of selectively laser-melted 316L stainless steel was studied and it was found that the smaller the feature produced by selective laser melting, the higher is the mechanical strength.

Rapid Manufacturing of Metal Components by Laser Forming
TL;DR: In this article, the main driving force of rapid prototyping or layer manufacturing techniques changed from fabrication of prototypes to rapid tooling (RT) and rapid manufacturing (RM), and nowadays, the direct fabrication of functional or structural end-use products made by layer manufacturing methods, i.e. RM, is the main trend.
