Abstract The project explores the possibility of using additive manufacturing (AM) of ceramic materials to produce ceramic tools for metal cutting. Among other advantages, this concept aims to manufacture ceramic tools with optimized cutting geometries, provide them with customized texturing of the cutting surface, generate [...]

Abstract Ceramic materials are gaining relevance in Additive Manufacturing (AM), although the lack of standardized process parameters limits the repeatability and comparability of printed parts. This study proposes an optimization procedure for the fabrication of alumina (Al₂O₃) components using Fused Deposition Modelling (FDM) with a [...]

Abstract The company DOGRAM is involved in an international CDTI project, entitled PV-Box-Grow, in which it provides support for the assembly and dimensional verification of large-scale structures for mounting marine solar panels. The project combines “hybrid” non-contact measurements obtained using different reverse-engineering technologies and equipment [...]

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 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 variety of equipment implementing laser triangulation technology for 3D scanning makes it difficult to analyse their performance, comparability, and traceability. In this study, three laser triangulation sensors arranged in different configurations are analysed using high precision spheres made of different materials and surface [...]

Abstract Additive Manufacturing (AM) is advancing technologically towards the production of components for high-demand mechanical applications with stringent dimensional accuracy, leveraging metallic and ceramic raw materials. The AM process for ceramic components, known as Ultraviolet Laser Stereolithography (SLA), enables the fabrication of unique parts or [...]

Abstract The characteristics of additively manufactured parts (topological optimisation, freedom of design …) present a challenge from a metrological point of view. In this respect, non-contact inspection is of great importance for the rapid verification of this type of parts. However, their particular characteristics (stair-effect, [...]

Abstract The project aims to develop an integrated manufacturing and non-contact dimensional inspection system using sensors based on Conoscopic Holography (CH). To this end, these sensors will be integrated into machine tools, initially three-axis machines, by developing the necessary mounting, communication, control, and calibration systems, [...]

Abstract The advantages of non-contact digitising systems over contact systems are undeniable. They allow capturing more information per unit of time with less accessibility problems and without alter the digitised surface. Although many of these systems have been developed with the aim of replacing contact [...]
