New 3D-printing method builds structures with two metals

Taking a cue from the structural complexity of trees and bones, engineers have created a way to 3D-print two types of steel in the same circular layer using two welding machines. The resulting bimetallic material proved 33% to 42% stronger than either metal alone.
