3D Printing Method Builds Structures with Two Metals

Taking a cue from the structural complexity of trees and bones, Washington State University 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 33–42 percent stronger than either metal alone, thanks in part to pressure caused between the metals as they cool together.
