Apoyo técnico para el análisis de viabilidad y conceptualización de un sistema de ingeniería inversa basado en tecnologías de escaneado 3D (Project Rosetta)

Abstract: In this project, EPMAN conducted an in-depth analysis of AEGIS’s reverse engineering requirements. AEGIS manages a significant number of modification projects involving in-service train fleets, often with limited or outdated design information and little involvement from the original manufacturer. Based on this analysis, EPMAN [...]

Accuracy Enhancement of Metal MEX Manufactured Parts through Geometry Compensation and Data-Driven Optimization (AEMMEX)

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 [...]

Layer contour geometric characterization in MEX/P through CIS-based adaptive edge detection

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 [...]
