“…By teaching sustainability through 3DP in these countries, students can learn how to design and produce environmentally friendly and costeffective products [12], which can be used to address some of the sustainability challenges these countries face. Using 3DP technology can also help promote local manufacturing and reduce dependence on imported goods [13], positively impacting local economies.…”

One of the many features of three-dimensional printing (3DP) that contribute to its status as a cutting-edge technology is its positive impact on sustainability. Students in higher education can also use 3DP technologies to understand environmental, social, and economic issues. However, there is a lack of knowledge on how sustainability is integrated through 3DP in higher education, especially in developing countries. Thus, this research explored the teaching of sustainability through 3DP in five public engineering universities in Vietnam using field observations (75 students and five educators), followed by semi-structured interviews with ten students and five educators. The findings revealed that sustainability through 3DP was not taught as a separate unit in the participating institutions as they were not equipped with the necessary tools and software to educate students about sustainability through 3DP, the time spent teaching students about 3DP was limited, and most of the educators were not trained in implementing sustainability through 3DP in higher education. Despite these barriers, students were instructed on how to use 3DP materials economically and were taught which materials were beneficial for the environment. In cases of limited resources and funding, assisting students in assembling low-cost do-it-yourself 3D printers by utilizing open-source materials will maximize their learning outcomes. These findings may help higher education institutions teach sustainability through 3DP and motivate students to explore multidisciplinary knowledge in developing countries. This study also guides both higher education sectors and policymakers on taking the steps necessary for utilizing the benefits of 3DP in engineering education.

“…Unlike phase inversion and spinning techniques for membrane fabrication, 3D printing offers many advantages, including simplicity, eco-friendliness, design efficiency, and the capability to produce complex geometries. [14][15][16][17][18][19][20][21][22] 3D printing is also cost-effective as it eliminates solvents and other tooling materials, demonstrating the capability to tailor surface areas for enhanced contact with gasses. 14,17,23 With flexibility in computeraided printable structures, multifunctional carboncapturing materials, such as process-intensified devices (i.e., packing devices integrated with heat exchangers for temperature control inside the CO 2 absorption columns), 17 complex structures [24][25][26] can be producedmaking 3D printing more attractive compared to other fabrication techniques.…”

Polydimethylsiloxane (PDMS)‐based membranes containing amine‐functionalized and unfunctionalized silica particles were fabricated via direct ink writing for CO2/N2 gas separation. The printability of the inks was evaluated by rheological measurements, while spectroscopy, microscopy, thermal measurements, and mechanical testing were employed to characterize the printed membranes. The surface morphology of the membranes revealed the absence of voids, demonstrating their suitability for gas separation. The printed membranes also exhibited desirable thermal and mechanical properties (i.e., thermal degradation temperature of 518 °C and tensile strength as high as 1.178 MPa with 529% elongation). The PDMS‐based membranes generally displayed high permeability for CO2 but slightly low selectivity for the CO2/N2 gas pair. The best‐combined permeability‐selectivity performance of 8794 barrer and selectivity of 11.64 was demonstrated by the printed PDMS membrane containing no SiO2 fillers. The inclusion of unfunctionalized SiO2 particles generally increased the membrane's gas permeability but compromised the selectivity. In contrast, membranes with amine‐functionalized silica showed improved selectivity compared to membranes containing unfunctionalized silica. Overall, the performance and characteristics offered by the PDMS/silica composite membranes demonstrated the potential of 3D printing as an economical and sustainable fabrication approach to developing materials for carbon capture applications.

“…The superiority of these technologies over traditional ones, which necessitate the removal of surplus material and involve long manufacturing time, is significant. AM technologies align with the principles of sustainable development due to their minimal waste output [7][8][9], and they facilitate the recycling of materials, thereby improving economic efficiency and environmental care [10][11][12][13][14][15][16][17]. One of the most salient advantages of 3D printing is its ability to speed up the process of product development and validation through rapid prototyping.…”

Additive manufacturing technologies (or 3D printing) have emerged as potent tools in the creation of a diverse array of objects, promising a paradigm shift in production methodologies across industries. However, the benefits of these technologies can be diminished by the use of suboptimal parameters or inferior materials, leading to defects that significantly degrade the quality and functionality of the resulting products. An incomplete understanding of defect formation keeps under the formulation of effective preventative strategies. In light of this, our review provides a comprehensive exploration of defects that arise during the Fused Filament Fabrication (FFF)—one of the most prevalent 3D printing methods. The defects are systematically classified according to several key characteristics, including size, type, mode of occurrence, and location. Each common defect is extensively discussed, detailing its external manifestation, root causes, the impact on the properties of printed parts, and potential preventative measures. Our findings unveil the complex interplay of material properties, printing parameters, and cooling dynamics in the defect formation process. This classification holds significant practical relevance, providing a solid foundation for the development of strategies for defect minimization and quality improvement in 3D printed products. It offers valuable insights for a broad audience, including researchers exploring additive manufacturing technologies, 3D printing engineers, 3D printer operators, and quality assurance (QA) engineers involved in production quality control. Furthermore, our review delineates the path for future research in this domain. There is a crucial need for the development of advanced machine learning and artificial intelligence models that can predict defect formation based on given printing parameters and material properties. Future investigations should also focus on the discovery of novel materials and refining of printing parameters to achieve superior quality of FFF 3D printed products. This review serves as a cornerstone for these future advancements, promoting a deeper understanding of defect formation and prevention in additive manufacturing.
