Surface texturing has brought significant improvements in the functional properties of parts and components. Sinker electro discharge machining (SEDM) is one of the processes which generates great texturing results at different scale. An electrode is needed to reproduce the geometry to be textured. Some geometries are difficult or impossible to achieve on an electrode using conventional and even unconventional machining methods. This work sets out the advances made in the manufacturing of copper electrodes for electro erosion by additive manufacturing, and their subsequent application to the functional texturing of Al-Cu UNS A92024-T3 alloy. A combined procedure of digital light processing (DLP) additive manufacturing, sputtering and micro-electroforming (AMSME), has been used to produce electrodes. Also, a specific laboratory equipment has been developed to reproduce details on a microscopic scale. Shells with outgoing spherical geometries pattern have been manufactured. AMSME process has shown ability to copper electrodes manufacturing. A highly detailed surface on a micrometric scale have been achieved. Copper shells with minimum thickness close to 300 µm have been tested in sinker electro discharge machining (SEDM) and have been shown very good performance in surface finishing operations. The method has shown great potential for use in surfaces texturing.

This work has come about as a result of an attempt to improve educational practices by taking advantage of research experience in the field of additive manufacturing technologies. As a result of the work carried out, an open educational resources project was developed by the group of educational innovation Ingeniería de Fabricación of the University of Las Palmas de Gran Canaria. It consists of interactive teaching material adapted to the new international standards that regulate these technologies and includes a methodology for selecting the most appropriate technology for the specific application. In this paper, we describe the co-creation process that was carried out with students in order to develop the resources, as well as a description of the didactic material itself together with its interactive elements. An analysis of its use in various academic courses is included and also an evaluation of its impact, both in teaching a specific subject and in other training activities. Our findings indicate that the process has led to the production of didactic materials that present content in an attractive way and which, in combination with active methodologies, noticeably improves students’ learning experiences, and is also considered a successful experience in open educational practices.

The purpose of this chapter is to describe experience in the development, use, and evaluation of interactive didactic material oriented towards the ISO GPS system that has been introduced into recent academic courses of subjects of various engineering degrees at the University of Las Palmas de Gran Canaria. The Educational Innovation Group Ingeniería de Fabricación sought to generate a tool that would help students with a learning difficulty that had been identified as generalizable across various degree subjects. Student feedback was utilized in the development and evaluation of this didactic material. The results obtained allow us to confirm that the introduction of these materials has had a positive impact and that this preliminary experience of adaptive learning should be supplemented further in order to extend the significant improvement observed, both in the students' learning and the lecturers' teaching, in the last academic year.

Research about selection has been focused to the material and current process selection methodologies/tools have problems. Consequently, a methodology for preliminary process selection was created through its integration in a design process. It allows manufacturing influence in early design stages through creating organizational knowledge. This storage of learning, integration and minimum viable product are key aspects. This paper addresses its application in industrial and university environments: manufacturing companies, design professionals, subject and final degree project. The obtained results show that methodology is validated and that the use of existing Manufacturing Process Selection methodologies is not enough for a correct selection.

Currently, methodologies of manufacturing processes selection are not clearly oriented for the early phases of the design process. Industry 4.0 has offered new opportunities to improve the integration of design and manufacturing processes. As a result, a methodology based on Design for Manufacturing and Assembly and organisational knowledge was created through its integration into an existing design process: Gero’s function-behaviour-structure variables framework. This methodology, called Manufacturing Process Selection Integrated in the Design Process, has been included in Interactive Didactic Material, and its application is expected to contribute to the use of these kinds of tools which will be instrumental in training future Engineers.

Nowadays, there is an increased demand for micro-products and micro-components in many industry sectors therefore development of advanced manufacturing technologies and metrological instrumentation in this range, have thus become a critical issue and an engineering challenge. If a product cannot be measured, although it might be manufactured, it would not be possible to analyse its design in order to improve its functionality. Electroforming could be defined as the highly specialized use of electrodeposition for the manufacturing of metal parts. Due to progress in materials, processes and equipment, electroforming has shown considerable development. Consequently, electroforming is increasingly combined with other micro-manufacturing technologies, giving rise to other processes such as LIGA and UV-LIGA. Thanks to the accumulated experience of Fabricación Integrada y Avanzada research group, of the University of Las Palmas de Gran Canaria in the electroforming process focused on macro-scale, as well as specific equipment available, this paper aims to analyse the potential of electroforming process for micro-injection mould manufacturing.

Electroforming enables the manufacture metallic parts with good mechanical properties and high level of accuracy and reproducibility. A thin metallic shell is deposited on a model and later released from it. There are several applications of electroforming combined with rapid manufacturing (RM) technologies. However the two main disadvantages of electroforming are the non-uniformity thickness distribution and long time span of shell manufacturing. The goal of this research is the evolution of Elecform3D™ product. It is a numerical simulation tool of electroforming process, in order to facilitate design and manufacturing tasks for metallic shells production. This software also controls the automatic device of cathodic orientation (ADCO) inside electrolytic baths. High quality of part is obtained, taking advantage of electroforming properties and improving manufacturing speed. The methodology is based on the well-known potentials model of LaPlace, it enables deposited metal distribution prediction with high grade of precision, being experimentally validated with cathodic polarization curves. Moreover this has also created a subroutine for solving this problem for this application using the boundary element method (BEM). This tool has been tested and validated for the simulation of metal electroplating by using reference solutions of problems in the literature. It also examines changes in the geometry of the cathode as a result of the process of electro-deposition of the metal and the influence of this phenomenon on the simulation routine developed considering variables such as the metal thickness distribution and the rate of deposition. All these tasks work and carry out processes complementing simulation with experimental work in the laboratory in order to create a tool that will give greater potential to this product. The results obtained with the first version of this product were very promising, and also indicated the need for a more precise analysis of electrochemical phenomena in the process of electroforming. Elecform3D™ is an important step beyond electroforming so far, and combined with additive manufacturing (AM) 3D printer, is a cheaper alternative for high quality metallic parts manufacturing in comparison with other RM technologies.
