MD-Lab provided laboratory testing and engineering validation for maritime UAV prototypes developed with A.S. Prote Maritime Ltd. The work covered prototype preparation, static structural checks, dynamic vibration measurements, FFT-based response processing, reverse engineering and aerodynamic simulation support, creating a coherent pathway from physical testing to numerical validation.
3BUILD developed a lightweight, portable robotic mortar printer for buildings and infrastructure, bringing large-scale 3D printing in construction from laboratory trials to a full-scale demonstrator. The project concluded with the construction of the first 3D-printed house in Greece at the TITAN Elefsina Plant.
NOESIS developed and demonstrated a new generation of vibration and seismic protection devices for all spatial directions. The project was built around the KDamper concept, an innovative isolation and absorption architecture that uses negative-stiffness elements to protect structures, equipment and sensitive installations from seismic and other low-frequency excitations.
A controlled experimental characterization project for ELVAL COLOUR S.A., focused on the damping behavior of composite aluminium plates. MD-Lab developed the mechanical test setup, manufactured a dedicated auxiliary aluminium plate and fixture system, and carried out vibration measurements according to DIN EN ISO 6721-1 and -3. Detailed numerical results and material comparisons are omitted from this public summary due to confidentiality.
HEV (High Energy Ventilator) was a CERN-affiliated emergency ventilator initiative developed in response to the COVID-19 pandemic. The project aimed to create a high-quality, versatile and lower-cost medical ventilator design, developed in consultation with medical professionals and based on accessible components. Within the HEV effort, MD-Lab focused on the modelling and design of a scroll compressor capable of supplying compressed air to the ventilator system.
A dedicated surgical-assist tool for controlled acetabular cup medialization in total hip arthroplasty. Developed with the 2nd Department of Orthopaedics of Athens General Hospital “G. Gennimatas”, engineered by MD-Lab, and manufactured by Prematech from biocompatible SAE 316L stainless steel, the prototype helps surgeons transfer impaction loads more effectively while preserving cup orientation.
Research on plastic gear transmissions at MD-Lab combines material-model development, finite-element and neural-network surrogate modelling, dynamic/NVH simulation, and additive manufacturing technologies. Key results include neural-network surrogates that reproduce finite-element static transmission error curves for polymer gears with 0.49% MAPE, dynamic simulations showing reduced vibration levels compared with metallic gearsets, and additive-manufacturing studies that quantify FDM and other 3D-printing accuracy limits while investigating wear resistance and wear patterns in printed gears.
Multi-objective optimization of gear tooth profiles to improve weight, efficiency, dynamic behavior, and wear performance, focusing on both involute macro-geometry and free-form non-involute profiles. Key results include more than 40% reduction in power losses and 35% reduction in vibration RMS for optimized involute gears. For free-form gears, reductions of up to 55% in average wear depth and 70% in maximum wear depth have been achieved.
The second year students are informed that the make-up of the course Elements of Machinery II, which was lost due…
