Stress relief for additive layer manufacturing

Abstract

The present disclosure relates to techniques for stress relief in additive layer manufacturing (ALM). Example embodiments include a method for additive layer manufacturing of a metallic component, comprising the steps of: providing a substrate (20); depositing a first layer (22) of material on the substrate (20); depositing a plurality of second layers of material on the first layer (22) to form the metallic component (21), wherein the first layer (22) forms a stress relieving layer between the plurality of second layers and the substrate (20), the stress relieving layer having a lower shear stiffness compared to the metallic component (21).
