Short CV:
G. Valiño earned an MSc in Industrial Engineering (1994) and a PhD (2004) from the University of Oviedo, Spain. After three years in the metalworking industry, he joined the Department of Construction and Manufacturing Engineering at the University of Oviedo in 1998 as an Associate Lecturer, becoming a Senior Lecturer in 2006. His research focuses on automation, manufacturing process planning, integrating inspection and digitizing sensors into production machines. He is currently working on enhancing the precision of additive manufacturing (AM) processes. He has served as Principal Investigator on three projects and as co-Principal Investigator on one ongoing project. He has published more than 50 works, including papers in indexed journals and conference proceedings.

Abstract This project provided technological support for the development of an optical human face digitization system aimed at customizing 3D-printed oronasal masks. Two acquisition strategies (simultaneous and progressive) were analyzed and compared. A test bench incorporating simplified prototypes was designed and built, and different configurations [...]

Feasibility of Conoscopic Holography Measurement in the Stereolithography (SLA) Process with Alumina
Abstract As additive manufacturing technologies continue to gain ground in industrial applications, the need for the accurate metrological evaluation of parts produced with advanced materials becomes increasingly critical. In this context, non-contact metrology plays a key role. This research investigates the performance of conoscopic holography [...]

Abstract The processes utilized for Additive Manufacturing (AM) production of metallic parts usually entail the use of hazardous feedstocks, expensive production equipment, and high energy consumption. Metal Material Extrusion AM (MEX/M) presents an alternative multi-step approach that addresses these challenges by additively extruding polymer-metal composite [...]

Abstract: The industrial adoption of material extrusion of polymers (MEX/P) is hindered by the geometric quality of manufactured parts. Contact image sensors (CISs), commonly used in flatbed scanners, have been proposed as a suitable technology for layer-wise characterization of contour deviations, paving the way for [...]
