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 data (logs, images, point clouds, [...]

Type: PhD Title: Compensation of geometrical errors of parts obtained by fused filament additive fabrication Author: F. Peña Supervisor: J.C. Rico; G. Valiño Related Project: DPI2017-83068-P Date: 19/10/2023

Abstract Additive manufacturing has undergone a rapid development in recent decades, evolving from prototyping and individual part fabrication to fabrication of functional components and serial production. The progressive reduction of the cost per unit has transformed additive manufacturing into a viable alternative to conventional processes for certain applications. However, the [...]

Abstract This Doctoral Thesis investigates the feasibility of integrating non-contact sensors based on Conoscopic Holography (CH) technology into CNC production machines for inspection and verification tasks. A practical integration methodology was developed, comprising three levels: physical installation of the sensor, calibration of the machine-sensor system, and automation of the measurement [...]
