Dr. Mateusz Cieślik conducts research focused on the development, modification, and characterization of conductive polymer composites dedicated to 3D printing applications in electrochemistry, particularly for chemical and biosensor devices. He specializes in additive manufacturing technologies, including fused deposition modelling (FDM), digital light processing (DLP), and selective laser sintering (SLS), for the fabrication of electroactive structures.

His work includes the design and optimization of polymer–carbon and polymer–diamond composites with enhanced charge transfer kinetics, as well as the development of surface activation techniques for 3D-printed electrodes using laser processing, enzymatic treatment, and electrochemical saponification.

Dr. Cieślik is the author and co-author of 22 scientific publications (350 citations, h-index = 11, Scopus 2024). His research interests combine additive manufacturing, electrochemical materials science, and applied surface engineering. His achievements include the development of a new generation of conductive filaments with fivefold higher charge transfer kinetics than commercial materials, the introduction of innovative laser and electrochemical surface activation methods for 3D-printed electrodes, and the co-development of a dual corrosion sensor system implemented at PKN Orlen S.A.

His work has been recognized with multiple awards for innovation, including the Grand Prix and Platinum Medal at INTARG® 2022 and a Silver Medal at the iENA International Trade Fair for Ideas, Inventions and New Products in Nuremberg.
