Additive Manufactured Aero-turbine Blade

Abstract

Additive Manufacturing has proven to be a demanding technique in a wide range for the aero-vehicle industries. This investigation focused on the evolution of aero-turbine blades from conventional manufacturing technique to the additive manufacturing technique. Additive Manufacturing is known as rapid prototyping or 3-D printing technique involving layer-by-layer construction process that can develop a turbine blade with a wide range of parameters to design the turbine blade and reduce cost and weight compared to the conventional production processes. This presentation discusses various additive manufacturing techniques suitable for manufacturing high-temperature turbine blades, such as selective laser melting, selective laser sintering, electron beam melting, laser engineering network form, and electron beam fabrication free form. The associated parameter of AM such as particle size and shape, powder bed density, residual stresses, porosity, and roughness are discussed here.
