a Research Fellow, and in 2012, became a Researcher. He holds practical classes in courses on electromagnetic field theory and mathematical analysis at the Politecnico di Torino. His research interests are in the areas of microwave leaky antennas, dielectric radomes, high-power feed systems (e.g., orthomode transducers (OMTs), microwave filters), corrugated horns, frequency-selective surfaces, and large dielectric radomes.

Massimo Lorusso was born in Alessandria, Italy, in 1982. He received the M.Sc. in materials engineering in 2009 and the Ph.D. degree in materials science and technology in 2013, both at Politecnico di Torino, Turin, Italy.

From June 2009 to August 2011 and from September 2012 to August 2014, he worked in the Materials Science and Chemical Engineering Department at Politecnico di Torino as a Research Assistant. The research activities were focused

on the development and characterization of coatings for functional applications. From September 2011 to August 2012, he worked in Politechnika èoÂdzka, Poland, as a Research Assistant. His main activity was the development of PVD coatings for functional applications for the European project MaMiNa (Marie Curie Action). In 2013, he lectured in "Materials for Precision Manufacturing" at Scuola Universitaria Professionale della Svizzera italiana (SUPSI), Switzerland. In September 2014, he joined the Istituto Italiano di Tecnologia (IIT). His research activity in the Additive Manufacturing/3D Printing Research Line of Center for Sustainable Futures CSF@POLITO is focused on the characterization of materials and components fabricated through additive manufacturing (AM) and, more specifically, through the Selective Laser Melting (SLM) technique.

Elisa Paola Ambrosio, was born in Turin, Italy, in 1976. After the M.Sc. in industrial chemistry at UniversitaÁ degli Studi di Torino, in 2000, she worked as a Failure Analysis Engineer at International Rectifier, focusing on the electrical and structural characterization of semiconductors. In January 2005, she joined the Material Science and Chemical Engineer Department at Politecnico di Torino, Turin, Italy. The research activities were focused on the synthesis and characteriza-

tion (structural and electrochemical) of catalyst supports for PEMFC (Proton Exchange Membrane Fuel Cell), on the preparation and characterization of MMC (Metal Matrix Composites) for aerospace application, and on the characterization of SiC foams and carbon derived polymeric resins (She received the Ph.D. degree in 2008, in Materials Science and Technology, at Politecnico di Torino).

2009, he held lectures for the Materials for Cutting Tools master course in the Materials for Precision Manufacturing module as an Invited Professor at Scuola Universitaria Professionale della Svizzera Italiana (SUPSI) in Manno, Switzerland. Since 2010, he joined the Istituto Italiano di Tecnologia (IIT). His research activity, in the Additive Manufacturing/3D Printing Research Line of the Center for Sustainable Futures CSF@POLITO, is now focused on lightweight structural and functional components for various applications fabricated through additive manufacturing (AM). This approach significantly extends the freedom of design and manufacture

by allowing, for example, the creation of an object with a desired shape and internal structure in a single fabrication step. The design of the part can be tailored to meet specific functions and properties (e.g., physical, mechanical, chemical, biological, etc.) using different and custom developed materials. He holds one European patent and is the author and/or co-author of three book chapters, more than 30 papers in international journals, and about 40 communications for national and international scientific conferences.
