Dr Nicolas Hadjipantelis is Assistant Professor of Structural Engineering at the Department of Civil and Environmental Engineering at the University of Cyprus, where he is conducting research in the area of Steel Structures and is teaching courses related to the design of steel structures and structural stability at both undergraduate and postgraduate level.

Dr Hadjipantelis is the founder and leader of the Steel Structures Laboratory at the University of Cyprus, which comprises a state-of-the-art Wire Arc Additive Manufacturing (WAAM), also known as Wire-Arc Directed Energy Deposition (DED-Arc), system. Dr Hadjipantelis has several years of experience in the research area of WAAM, specifically in the production, testing, modelling, and development of design rules for WAAM structures. His research interests also lie in the areas of cold-formed steel structures, prestressed steel structures and structural stability.

Recently, he was awarded the Teaching Excellence Award 2026 by the Center for Teaching and Learning of the University of Cyprus. This award is presented (every two years per Faculty) to academic staff who demonstrate outstanding teaching performance, pedagogical innovation and strong engagement with the students, within the framework of the University of Cyprus’ policy for ensuring and promoting excellence in teaching.

Dr Hadjipantelis holds a PhD in Steel Structures from Imperial College London, for which he was awarded an Imperial College President’s Scholarship. As part of his undergraduate studies at the University of Bristol, where he obtained a first class honours MEng degree in Civil Engineering, he studied and conducted research for an academic year at the University of California, Berkeley. Before joining the University of Cyprus in August 2020, Dr Hadjipantelis has worked for two years as a Research Associate at Imperial College London in affiliation with The Alan Turing Institute.

Dr Hadjipantelis is National Representative & Committee Member for CEN/TC 250/SC 3 and Member of the CEN/TC 250/SC 3 Ad-Hoc Group on the 'Design of Steel Structures featuring DED-Arc', which works on the integration of design provisions in the next generation of Eurocode 3 that will cover the use of WAAM in steel construction.

Wire Arc Additive Manufacturing / Wire-arc directed energy deposition

The Steel Structures Laboratory of the University of Cyprus has developed a state-of-the-art Wire Arc Additive Manufacturing (WAAM) facility capable of printing bimetallic structures in a fully-automated mode. WAAM is a large-scale robotic metal 3D printing technique that employs a robotic arm in conjunction with a welding machine to print metal components of any desired geometry and size in a layer-upon-layer fashion. To date, the WAAM facility of the Steel Structures Laboratory has been used to produce more than one tonne of specimens for structural testing at a material, member and system level. You can watch a presentation by Dr Hadjipantelis outlining the use of WAAM in construction in this video (in Greek).
