Nowadays, additive manufacturing, including the one of metallic components, opens up a new horizon for aeromechanical optimisation of the gas turbine components, allowing for better efficiency and non-dimensional performance. However, additively manufactured turbine components require a new approach to design in general. In the paper we consider a lifecycle of a single component, particularly, a blade for a low speed compressor test rig, designed by means of generative design and produced by means of FDM 3D printing technology. Design process included consideration of all the limitations, then computational study, manufacturing and further operation at the experimental facility. As a result of generative design, manufactured blade used less material and took less time to print with sufficient stress margin. However, the product of generative design algorithm was manually reworked before the final CAD model was processed further on. An experimental set of blades was then tested on the rig and proved its reliability.
