Surfaces functionalization and postprocessing for industrial applications
Original language description
Functional 3D structure on 3D printed blade, optimized for hydraulic and mechanical performance. The aim of this technology is to enable the advanced production of geometrically complex hydraulic pump blades made from AISI 304L stainless steel using Selective Laser Melting (SLM) and subsequent Laser Shock Peening (LSP) surface treatment. The technology combines the advantages of additive manufacturing—particularly design freedom and the ability to create special 3D surface structures—with LSP surface strengthening to increase the durability of the parts in demanding operating conditions, such as exposure to cavitation. The result is a proven method for manufacturing blades with advanced 3D surface structures and enhanced functional properties.

Technical parameters
3D printed blades of an impeller for a model pump of specific speed ns=600. The impeller has six adjustable blades and the pump is designed (when operated at 1 750 rpm) for working range from 250 to 550 l/s, head 14 m at the design point of 450 l/s and power up to 100 kW. Kontaktní údaje: Michal Ackermann, michal.ackermann@tul.cz
Economical parameters
The model pump will be used as a baseline for commercial pumps, where the design is scaled up to meet the performance requirements (typically MWs of power). Most typical application is water pumping, where the improved hydraulic performance brings competitive advantage on the market. Typical cost of such contract foe water pumping station contains multiple pumps and costs from tens to hundreds of milions CZK. Contact: Michal Ackermann, michal.ackermann@tul.cz
