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 [...]

Abstract This project investigated and evaluated how to automatically generate a customized oronasal mask (PPE) model adapted to each user’s face, based on facial scanning data and a generic model designed for additive manufacturing using an elastic material. The work covered the characterization of the [...]

Abstract Filament-based material extrusion has evolved from a low-cost prototyping technique into a manufacturing process increasingly considered for functional and quality-critical applications. However, its industrial adoption remains constrained by a persistent traceability gap between planned process parameters and final part outcomes. During fabrication, heterogeneous monitoring [...]

Abstract Additive manufacturing (AM) has faced challenges in achieving the part accuracy required for industrial adoption. Most research has focused on offline inspection of geometric deviations in test parts. This paper introduces a novel approach to enhance part accuracy and process control in Polymer Extrusion [...]

Abstract The project aims to develop and optimize the additive manufacturing of metal parts using Metal Extrusion (MEX/M) as an alternative to conventional metal powder-based technologies, with the goal of reducing costs, energy consumption, and the risks associated with the handling of raw materials. The [...]

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 purpose of this paper is to provide a new procedure for in-plane compensation of geometric errors that often appear in the layers deposited by an additive manufacturing (AM) process when building a part, regardless of the complexity of the layer geometry. The procedure [...]
