Abstract
Purpose
The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.
Design/methodology/approach
The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.
Findings
The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.
Originality/value
AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.

Abstract
Purpose
This study aims to determine the contribution of financial skills to entrepreneurial intentions among women involved in university education.
Design/methodology/approach
Clustering and logistic regression analyses were used to infer the determinants and motivators of entrepreneurial intention in a sample of women students at a Spanish online university.
Findings
Financial and numerical skills could play a significant role in boosting entrepreneurial culture, overcoming reticence and increasing awareness of business opportunities, particularly when women are motivated to increase their autonomy and income. The study offers meaningful implications for policymakers.
Research limitations/implications
Further research will be needed before these conclusions may be inferred to other settings and circumstances. Comparison with a similar sample of potential male entrepreneurs may also be necessary to deduce the influence of gender.
Practical implications
The introduction of certain financial content into the education system by governments and policymakers would produce remarkable results on entrepreneurship intention among women.
Social implications
Relational capital and positive social influences also contribute to mitigating the effects of risk aversion, one of the main barriers for potential female entrepreneurs.
Originality/value
The role of financial literacy in entrepreneurial intention among women has scarcely been addressed in academic research. The literature also has paid little attention to the analysis of what motivates women into entrepreneurship, and whether women who decide to embark on a business venture show different profiles. The aim of this study is to contribute to closing these gaps, exploring the effect of cognitive skills, personality traits, contextual factors and motivations.
