About
Ankur Majumdar
Postgraduate Researcher
DCU
Ankur Majumdar is a PhD researcher at the Advanced Metallic Systems Centre for Doctoral Training, based at I-Form, Dublin City University (DCU), specialising in the additive manufacturing of Nickel Titanium actuators. He earned his undergraduate degree in Mechanical Engineering from the University of Mumbai, India, and went on to complete a Master’s degree in Mechanical Engineering at the University of Kentucky, USA. Following his Master’s studies, he gained valuable industry experience through various roles, including Field Service Engineer at Heidelberg Instruments USA, Maintenance Engineer at Jindal India, and Mechanical Design Engineer at Franklin Electric USA and TEMA India. Driven by a renewed interest in research, he joined the Indian Institute of Technology Bombay as a Senior Research Fellow before commencing his PhD studies at DCU. His primary research interests include metal additive manufacturing, specifically Laser Powder Bed Fusion (PBF-LB), with a focus on in-process monitoring, the development of porous structures, material characterisation, and their integrated application in actuator systems.
Technical Summary
Ankur's research focuses on the development of Nickel Titanium (NiTi) actuators fabricated via Laser Powder Bed Fusion (PBF-LB) additive manufacturing, targeting applications in the aerospace, biomedical, and automotive industries. He aims to optimise material properties and actuation performance by systematically varying material composition, processing parameters, and post-processing techniques. This approach leverages the precise control offered by PBF-LB, which selectively melts and fuses powder layers to produce intricate geometries and tailored microstructures. Specifically, Ankur is investigating how these variables influence the physical properties of NiTi and, in turn, the performance of the actuators. His objective is to establish optimal parameter sets for specific applications, enabling the fabrication of actuators with precisely defined characteristics.
