In early March, researchers from the Laboratory for Fluid Power (LFT) attended the 15th International Fluid Power Colloquium (IFK) in Aachen—one of the largest and most significant international scientific events in the field of fluid power. The conference brings together leading global researchers and industry experts, facilitating the exchange of knowledge regarding hydraulic and pneumatic drives as well as advanced control systems. At the conference, we presented three scientific papers addressing current challenges in modern hydraulics, ranging from new materials to the cleanliness of assemblies:
Evaluating Sliding Properties of Selective Laser Melted Maraging Steel against Aluminium Alloys in Water and Hydraulic Oil
Dr. Ana Trajkovski
This paper examines the sliding properties of maraging steel—produced via selective laser melting—when in contact with aluminium alloys in water and hydraulic oil.
3D-Printed Polymer and Ceramic Spools as Alternatives to Steel for Hydraulic Valves
Jan Bartolj
This research investigates the potential use of 3D-printed polymer and ceramic control spools as lightweight, cost-effective alternatives to steel components in hydraulic valves.
Innovative Approach to Cleaning and Cleanliness Control of Newly Manufactured Hydraulic Assemblies
Dr. Nejc Novak
A novel approach to the cleaning and cleanliness control of hydraulic assemblies is presented; this process significantly impacts the reliability, efficiency, and service life of hydraulic systems.

Participation in IFK 2026 reaffirms LFT’s active role in the development of new technologies and our commitment to cutting-edge research in the field of fluid power technology.
