“Non-Conventional Wing Structure Design with Lattice Infilled through Design for Additive Manufacturing”

The following is an interview with Prof. Dr. Aniello Riccio: 

1. Congratulations on your published paper. Could you please briefly introduce the main research content of the published paper?
   Thanks! Our paper investigates the feasibility of replacing conventional spar–rib wing structures with lattice-infilled designs enabled by additive manufacturing. By combining nTop implicit modeling with ANSYS simulations, we evaluated five different lattice configurations. The results demonstrated that the Kelvin lattice offers the best balance of stiffness, weight reduction, and stress distribution. This work highlights lattice infill as a promising alternative for lightweight aerospace wing structures. 

2. What are the key takeaways you hope readers will gain from your paper?
   We hope readers will appreciate that lattice-infilled designs, when optimized using advanced computational tools, can achieve significant weight savings—up to approximately 9.5%—without compromising structural integrity. Furthermore, we hope the paper clarifies that the choice of lattice unit cell has a strong influence on stress distribution and wing-tip deflection, making design-driven lattice selection crucial for optimal performance. 

3. Was there a specific experience or event in your research career that led you to focus on your current field of research?
   Yes. During my experience as a lecturer in aerospace structures and through subsequent collaborations on aerospace structural design with aircraft manufacturing companies, I became increasingly aware of the limitations imposed by conventional manufacturing technologies on implementing innovative geometries. Working with additive manufacturing, I recognized its potential to overcome these constraints and to rethink traditional aerospace structures by leveraging unprecedented design freedom. 

4. Could you describe the difficulties and breakthrough innovations encountered in your current research?
   A major challenge was managing the complexity of lattice generation and optimization, which traditional CAD tools cannot efficiently handle. The breakthrough came with the adoption of implicit modeling using nTop, combined with automated, Python-based iterative optimization. This approach enabled us to systematically evaluate multiple lattice topologies and directly link design parameters to finite element performance. 

5. Does technological progress provide new opportunities for the topic you are researching? Does it bring any potential risks? How do you think these factors will affect future research trends on this topic?
   Technological advances in additive manufacturing and generative design, including the integration of AI, clearly open new opportunities for lightweight aerospace structures. However, challenges remain, such as controlling process variability, meeting certification requirements, ensuring the robustness of AI approaches, and the necessity for complex experimental tests for validation of numerical results. Future research will likely focus on integrating multi-material printing, real-time process monitoring, and establishing robust certification pathways to ensure the safe adoption of these technologies in the aerospace industry. 

6. How do you evaluate research trends in this field, and what advice would you give to other young researchers?
   The field is rapidly evolving toward design for additive manufacturing (DfAM), with growing emphasis on lattice and metamaterial-based structures. My advice to young researchers is to build a strong foundation in structural mechanics, develop expertise in computational optimization and additive manufacturing technologies, and maintain an open mindset toward interdisciplinary collaboration. 

7. What appealed to you about the Materials journal that made you want to submit your paper? In your opinion, what can authors expect when they submit to Materials?
   We chose Materials because of its strong reputation for publishing high-quality research at the intersection of advanced materials and engineering applications, its broad multidisciplinary readership, and its efficient publication process. Authors can expect fair peer-review, constructive feedback, and timely publication. 

8. What is your experience publishing with Materials?
   Our experience was very positive. The review process was rigorous yet constructive, the editorial handling professional, and the publication timeline efficient. This enabled us to refine our work and reach a wider audience quickly. 

9. How do you think the open access way of publishing impacts authors?
   Open access significantly enhances the visibility and accessibility of research, ensuring that both academic peers and industry professionals can benefit without barriers. For authors, it increases citations, fosters collaboration, and accelerates the translation of research into practical applications.
