Laser metal deposition with wire (LMD-w) is a developing additive manufacturing (AM) technology that has a high deposition material rate and efficiency and is suitable for fabrication of large aerospace components. However, control of material properties, geometry, and residual stresses is needed before LMD-w technology can be widely adopted for the construction of critical structural components. In this study, we investigated the effect of interlayer cooling time, clamp constraints, and tool path strategy on part distortion and residual stresses in large-scale laser additive manufactured Ti-6Al-4V components using finite element method (FEM). The simulations were validated with the temperature and the distortion measurements obtained from a real LMD-w process. We found that a shorter interlayer cooling time, full clamping constraints on the build plates, and a bidirectional tool path with 180° rotation minimized part distortion and residual stresses and resulted in symmetric stress distribution.

The Ni3Al intermetallics involve more attention because of inherent material properties especially interesting in high temperature application. In this study the Selective laser melting (SLM) and Direct laser metal deposition (DLMD) are used to manufacture the single-tracks and layers. For the comparison of the methods, the optical microscopy, SEM, XRD and EDX microelement analysis were involved. The materials show no significant differences but each SLM and DLMD have the target application.
