Design materials based on simulation results of silicon induced segregation at AlSi10Mg interface fabricated by selective laser melting
TL;DR: In this article, the effects of the silicon-rich phase and Mg-containing structure on corrosion were studied by first-principles methods, and the results indicated that a local thermal gradient during laser printing caused Si segregation and the rapid cooling rate lead to a large number of subgrains, which assisted precipitation.

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.
