Abstract This project addresses an inefficiency identified at the Avilés steelworks: the cooling of the roller bearings in the continuous sheet annealing line. Based on technical documentation, thermal imaging, sound pressure measurements and on-site observations, the causes of the problem and the requirements for a solution are identified, prioritizing effectiveness [...]

Abstract This project forms part of an European Horizon Europe project on the bioprinting of living cells for regenerative medicine. Its aim is to design an extruder capable of regenerating human skin directly on the patient (in situ bioprinting). It involves reviewing extrusion technologies for this application, the conceptual and [...]

Abstract This project involves selecting and programming a time-of-flight (ToF) camera to digitize human faces for the manufacture of customized products, such as ergonomic masks. Initial tests were conducted on a test bench featuring vertical sensor displacement, using programs developed in C++ with Qt Creator, but the results were unsatisfactory. [...]

Abstract This project involves the study, design, manufacture, assembly and commissioning of a rotary MEX (Material Extrusion) print head featuring a non-circular nozzle and electromagnetic induction heating. It includes experimental testing of the induction heating process and detailed design supported by mechanical, thermal and electromagnetic simulations. The print head is [...]

Abstract In this project, two lines of research were investigated with the aim of laying the foundations for a stable, predictive, and intelligent manufacturing process capable of detecting and compensating for potential defects during the manufacturing process itself by modifying specific process parameters. The first line of work involved the [...]

Abstract This project develops a prototype printing head to integrate WAAM (Wire Arc Additive Manufacturing) technology into Triditive’s AMCELL 1400 printer. This would enable the company to manufacture metal parts using 3D printing and expand its market beyond polymer-based materials. The project covers a review of the state of the [...]

Abstract This project involves the study, design, manufacture, assembly, testing and implementation of a Cartridge system for Triditive that preserves filament during printing and minimizes its degradation. The system removes moisture through both active (temperature-based) and passive (silica gel) methods. Based on an analysis of a previous company prototype and [...]

Abstract This project involved the design, manufacturing, assembly, and commissioning of an additive manufacturing system with inspection capabilities. The manufacturing technology employed is fused thermoplastic filament deposition, while the inspection bridge is designed to accommodate different types of sensors. However, during the course of this project, the sensor installed on [...]

Abstract This project lays the foundations for a high-productivity extrusion head and investigates a new one-piece head concept incorporating heat dissipation and heating mechanisms that differ from conventional designs. The work follows three research lines aimed at reducing manufacturing time: the influence of nozzle geometry, the thermal profile and heat [...]

Abstract In theory, additive manufacturing can process virtually any material, but in practice, the range of available materials remains limited. This project develops a procedure and a guide for introducing engineering-grade materials into industrial applications through pellet-based additive manufacturing (pellet extrusion). Manufacturing parameters are established using purpose-designed test specimens. The [...]

Abstract This project updates the design of TRAC3D, an automated part storage system associated with Triditive’s AMCELL mass additive manufacturing machine, in which multiple printing arms operate within an enclosed chamber. The aim is to automate the storage and traceability of manufactured parts, enabling additive manufacturing production to scale up [...]

Abstract This project was carried out at Triditive, which aimed to incorporate an additional 3D printing method for metallic materials. It focuses on the design and development of the powder recoating system (the mechanism for spreading powder layers) for a Binder Jetting machine, a process in which a binding agent [...]

Abstract The objective of this project was to develop and implement a procedure for validating finite element simulations applied to the Laser Metal Deposition using powder (LMD Powder) Additive Manufacturing process. An experimental methodology was designed, covering the study of LMD Powder technology, experimental setup, model calibration, and final validation. [...]

Abstract This Master’s Thesis (MSc Thesis) is developed within the framework of the National R&D&i Plan project entitled “Real-Time Compensation of Layer Geometry Errors for Additive Manufacturing Processes”, funded by the Spanish Ministry of Science, Innovation and Universities (DPI2017-83068-P). The thesis focuses on the design and construction of an experimental [...]

Abstract In macrophotography, the depth of field is very shallow. Focus stacking addresses this limitation by capturing images at different focal planes and combining the in-focus regions of each image. The prototype integrates a camera mounted on a linear motion stage, a specimen positioning system, and software that manages the [...]

Abstract This project focuses on the evaluation, optimization and industrialization of an all-metal hot end for FFF additive manufacturing. An initial series of prototypes is evaluated, leading to improvements in several key areas: heater block insulation, the heat break–nozzle joint, PTFE tube retention, thermistor encapsulation, heater cartridge retention, fan mounting [...]

Abstract This study has enabled an analysis of the influence of the depth of field and the configuration parameters, frequency (F) and power (P), on the quality of measurements performed using a conoscopic holography (CH) sensor. To this end, tests were carried out on a stepped AISI 316 specimen, evaluating [...]
