Micro additive manufacturing using micro direct metal deposition
Fabrication of porous scaffolds with complicated internal architecture for biomedical application requires new and modern micro-manufacturing processes. Micro direct metal deposition (µDMD) is an additive manufacturing process which uses direct metal deposition (DMD) concept. It can implement smaller features than a conventional DMD process thanks to specific process parameters such as a small laser spot diameter and a new configuration of powder feeding system. µDMD has the ability to fabricate complex shapes with micro features. However, in order to improve the mechanical properties of µDMDed parts, microstructure control should be considered. This presentation examines how such process can be optimized via a set of process parameters and designed experiments for production of porous NiTi parts with micro features.
University of Padova, Researcher, Rovigo RO, Italien
Saeed Khademzadeh is a researcher and PhD student of mechanical engineering at the University of Padova, Italy. He also received a Ph.D. degree in metallurgy engineering from Tehran Polytechnic. He has been active in the area of metal micro additive manufacturing, and advanced materials characterization, for 5 years. During this period of time, he developed micro direct metal deposition process as a precision additive manufacturing method at precision manufacturing laboratory of University of Padova. He focused in particular on microstructural evolution and porosity measurements in additive manufactured micro parts. He has also published a number scientific papers in international journals and conferences in this field.
