| Technické parametry | Installation of additively manufactured blades to the pump unit and verification of its performance in real conditions. Evaluation of pump characteristics with regard to the newly added blades. Following the 3D print and LSP treatment, the blades were CNC machined to it is the final hydraulic shape and installed in the pump. To ensure a valid comparison with the previously tested (CNC machined and LSPed) blades, the configuration of the testing was exactly the same as in 2020. I.e. closed circuit with a pressure vessel. The pump was then extensively tested for hydraulic and operational characteristics and long-term resistance to intensive cavitation regimes.

| Ekonomické parametry | LSP surface treatment enables improvement of the Additive Manufacturing technology so it can be used for the production of critical parts and it can be used in the most demanding industries such as power generation, biomedical, etc. The advantages of the above-described process can be summarised in the following points: • Effectivity of the process from the energetic, financial and material points of view. • Possibility to produce individual geometries within one manufacturing cycle. • Additive manufacturing enables the use of special features such as a hollow inner core which may be filled with a lightweight structure. The surface of the blade can be defined to contain special elements enhancing the flow parameters of the liquid.

| Anotace | Our team proposed an innovative application of SLM additive manufacturing and LSP surface treatment in this area. We developed and designed new features for the blades which can be only achieved with the use of the two above-described technologies. We proved that manufacturing blades with progressive SLM technology are a very good option with promising possibilities for the future development. The use of a hollow core inside the body of the blade will lead to a reduction in weight. The specially designed surface contains small spherical indents in a predefined array. LSP was also proved to enhance the properties of the final product due to the fact that typical post-processing of the SLM part, such as heat treatment, is not sufficient so the component can be used for demanding applications or environments. By treating the areas of the blade that are directly under the influence of cavitation bubbles, it is possible to prolong the incubation time of cavitation and reduce mass loss.
