Abstract
A method for making an article is disclosed. The method involves first generating a digital model of the article. The digital model is inputted into an additive manufacturing apparatus comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a powder to fuse the powder to form the article corresponding to the digital model. The powder includes an aluminum alloy having 90.15-95.80 wt. % aluminum, 3.00-4.50 wt. % silicon, 0.70-1.50 wt. % magnesium, 0.50-1.00 wt. % manganese, 0-0.50 wt. % iron, 0-0.10 wt. % copper, 0-0.50 wt. % titanium, 0-0.20 wt. % boron, 0-1.50 wt. % nickel, and 0-0.05 wt. % other alloying elements, based on the total weight of the aluminum alloy.
