The development of new advanced materials, such as photopolymerizable resins for use in stereolithography (SLA) and Ti6Al4V manufacture via selective laser melting (SLM) processes, have gained significant attention in recent years. Their accuracy, multi-material capability and application in novel fields, such as implantology, biomedical, aviation and energy industries, underscore the growing importance of these materials. The purpose of this study is oriented toward the application of new advanced materials in stent manufacturing realized by 3D printing technologies.

The methodology for designing personalized medical devices, implies computed tomography (CT) or magnetic resonance (MR) techniques. By realizing segmentation, reverse engineering and deriving a 3D model of a blood vessel, a subsequent stent design is achieved. The tessellation process and 3D printing methods can then be used to produce these parts. In this context, the SLA technology, in close correlation with the new types of developed resins, has brought significant evolution, as demonstrated through the analyses that are realized in the research presented in this study. This study undertakes a comprehensive approach, establishing experimentally the characteristics of two new types of photopolymerizable resins (both undoped and doped with micro-ceramic powders), remarking their great accuracy for 3D modeling in die-casting techniques, especially in the production process of customized stents.

A series of analyses were conducted, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, mapping and roughness tests. Additionally, the structural integrity and molecular bonding of these resins were assessed by Fourier-transform infrared spectroscopy–attenuated total reflectance analysis. The research also explored the possibilities of using metallic alloys for producing the stents, comparing the direct manufacturing methods of stents’ struts by SLM technology using Ti6Al4V with stent models made from photopolymerizable resins using SLA. Furthermore, computer-aided engineering (CAE) simulations for two different stent struts were carried out, providing insights into the potential of using these materials and methods for realizing the production of stents.

This study covers advancements in materials and additive manufacturing methods but also approaches the use of CAE analysis, introducing in this way novel elements to the domain of customized stent manufacturing. The emerging applications of these resins, along with metallic alloys and 3D printing technologies, have brought significant contributions to the biomedical domain, as emphasized in this study. This study concludes by highlighting the current challenges and future research directions in the use of photopolymerizable resins and biocompatible metallic alloys, while also emphasizing the integration of artificial intelligence in the design process of customized stents by taking into consideration the 3D printing technologies that are used for producing these stents.

The research attempts to aim to evaluate the perception that different stakeholder groups have of one of the largest and most important Romanian university with respect to its sustainability orientation. The exploratory empirical research reveals some important aspects which must be closely pursued and properly implemented by the management of the university to further develop sustainability strategies. The paper offers a novel approach regarding the way a university can and must focus on different specific measures on sustainability to gain a better position on the educational market, to attract new students and lifelong learning (LLL) programme participants, as well as to become a trend setter for defining and transferring good practices within the society.

Data were collected by questionnaires and in-depth-interview guides which were distributed to different stakeholder groups: bachelor (undergraduate) and master’s students versus LLL programme participants coming from different high schools across the country enrolled on a training course organized by the university and high school principals versus staff members of the university holding coordination and/or management positions. The collected data were then analyzed by means of econometric analysis. Data validity, reliability and internal consistency were checked (Cronbach’s α coefficient, “item-to-total” correlation, the KMO criterion (>0.7) and Bartlett’s test of sphericity). With the help of exploratory factor analysis, the way in which different stakeholders value and perceive the specific measures and efforts undertaken by the university has been extracted.

Students, LLL participants and members of the university staff perceived the university’s positive orientation towards sustainability and the measures taken in this respect. All stakeholders expressed highly favourable opinions of the university’s dealings with different sustainability aspects, such as its attitude towards its employees, its performance within the higher education market and its establishment of an attractive and innovative educational programme, in compliance with sustainability principles, environmental protection and modern attitudes towards society.

The research has been conducted on a sample of students of bachelor and master level, belonging to the biggest faculty of the university (as to number of students and staff). In a more comprising study, the focus should also be on bachelor, master and PhD students of the other faculties of the university, as well as on citizens of the community or in general on people from Transylvania and/or Romania. The university under investigation is one of the most important employers of the region. Further dimensions of sustainable development could also be pursued in a future study.

The university shows an orientation towards civil society by means of specific actions and programs. The university supports and takes part in the organization of cultural and artistic events in cooperation with local authorities and other cultural and/or social institutions and organizations. Respondents also refer to some examples of best practices that might be applied by education institutions to educate young people towards developing a proper sustainable mentality.

There exist almost no comparative empirical studies of sustainability on Romanian universities that take account of the perspectives of students, LLL participants and staff members. The findings have a high potential in developing a proper strategy for the university involved but could also be used by the government if designing a national wide policy regarding this issue. Different authors argue that young people are more conscious about sustainability, organic stuff, environmental protection, green marketing, etc. Taking into consideration the sensitivity of young peoples (students, staff members, etc.), as well as the fact that the university establishes social trends, the idea of studying sustainability in a university could be regarded as a novelty approach.
