Abstract

Purpose

The purpose of this study is to cover the influence of selected printing parameters at a macro and micro-geometrical level, focusing on the dimensions, geometry and surface of printed parts with short carbon fibers reinforced PLA. For this case study, a hollow cylindrical shape is considered, aiming to cover the gap detected in previous works analyzed.

Design/methodology/approach

Nowadays, additive manufacturing plays a very important role in the manufacturing industry, as can be seen through its numerous research and applications that can be found. Within the engineering industry, geometrical tolerances are essential for the functionality of the parts and their assembly, but the variability in three-dimensional (3D) printing makes dimensional control a difficult task. Constant development in 3D printing allows, more and more, printed parts with controlled and narrowed geometrical deviations and tolerances. So, it is essential to continue narrowing the studies to achieve the optimal printed parts, optimizing the manufacturing process as well.

Findings

Results present the relation between the selected printing parameters and the resulting printed part, showing the main deviations and the eligible values to achieve a better tolerance control. Also, from these results obtained, we present a parametric model that relates the geometrical deviations considered in this study with the printing parameters. It can provide an overview of the piece before printing it and so, adjusting the printing parameters and reducing time and number of printings to achieve a good part.

Originality/value

The main contribution is the study of the geometry selected under a 3D printing process, which is important because it considers parts that are created to fit together and need to comply with the required tolerances. Also, we consider that the parametric model can be a suitable approach to selecting the optimal printing parameters before printing.

Abstract

In Spain, despite the increase of initiatives that promote the institutionalization of the Service-Learning (SL) methodology in the university sphere, the development of SL has been slow. The academic literature has noted this normative support, and in recent years there has been a proliferation of publications collecting research results, teaching innovation projects, and theoretical reflections on the benefits of SL. However, a current situation analysis of SL in Spain is still to be performed. Hence, this chapter aims to provide an overview of the current situation of SL in Spanish universities. A qualitative systematic review of the Spanish literature on SL in higher education is carried out by searching for original articles in English and Spanish in several databases. The principles established by PRISMA declaration for systematic reviews were followed.

The study reveals an increasing trend in the number of publications on the subject, although with significant differences between territories. Likewise, most of the studies used descriptive methods. In relation to the categories analyzed, the interest of the literature in the benefits obtained by university students through their participation in the experiences stands out, compared to the benefits obtained by the target group, the university–community relationship or the promotion of university social responsibility. The 50% articles included in the review refer to the effect of SL on the curriculum through teaching practices. Others evaluate the impact of the service, analyze dissemination actions of the experiences carried out, the future challenges for research on SL in Spanish universities, and the obstacles in the implementation of the experience.

Abstract

Purpose

This paper aims to focus on the evolution of nonprofit cultural institutions in Mexico and their relationship with Spain, regarding the four traditional elements of a marketing mix. Specifically, this paper examines marketing advancements in the digital environment, placing emphasis on the virtual exhibition Códices de México: Memorias y Saberes, as well as the marketing activities related to prehispanic and novohispanic codices between 2010 and 2022.

Design/methodology/approach

The first part of the present study provides a chronological framework based on the four components of a marketing mix, illustrating the transition of Mexican and Spanish public cultural institutions from their foundations to current times. It particularly provides insight into their recent accomplishments in the digital environment, underscoring potential networking areas. The second part offers an in-depth examination of the exhibition Códices de México: Memorias y Saberes (INAH 2015) and a review of digital sources from Mexican government entities to investigate marketing activities related to prehispanic and novohispanic codices.

Findings

Due to the historical approach used to document the transition of nonprofit cultural institutions in Mexico and Spain to the digital era, this article sheds lights on co-joint efforts in the digital marketing domain around prehispanic and novohispanic codices. Additionally, it illustrates the activities used by Mexican cultural institutions during the past two decades to disseminate knowledge on codices.

Research limitations/implications

Regarding the methodological aspects of using historical resources through digital archives, this study solely comprised marketing activities reported in the records available on the official portal of cultural institutions.

Originality/value

This study argues for the utility of the four components rooted in a traditional marketing mix as a tool to illustrate the evolution of marketing practices within the cultural heritage domain. It also highlights the role played by cultural institutions in Mexico and Spain in the digital environment to strategically network around cultural heritage. Additionally, it sheds light on the implementation of methods for presenting Mexican codices grounded in virtual terrain.
