Abstract

Reduction of the buy-to fly ratio through the utilisation of lean manufacturing processes for the next generation of components is an increasing area of interest in the aerospace industry. Powder bed Electron Beam Melting (EBM) is now rapidly being acknowledged as an innovative form of Additive Laye...
