Since the material is generated as the component is being built, aerospace manufacturers will begin tailoring the material’s properties across different areas of the part, Sharman said.This ‘functional loading’ can be used to adapt the microstructure and texture of the component at different points, to meet the varying load across the part. The final step would then be to change the composition of the alloy throughout the part, to meet different loads or requirements,

I had not even thought the now obvious idea that the powder bed can layered like a cake with powder of different qualities , or even different alloys . The EBM process allows on the fly changes in beam intensity and pattern
