Additive Layer Manufacturing (ALM) is an innovative manufacturing process which offers near-net shape fabrication of complex components. Among the various ALM processes, Selective Laser Melting (SLM) offers high geometrical freedom and a wide material range. However, as a result of the locally concentrated energy input, the temperature gradient mechanism and related plastification leads to significant residual stresses and deformation in the final product. Therefore this study concerns the residual stress measurements in an aerospace component fabricated through SLM from Ti- 6Al-4V powder.
