## 4 Discussion and Conclusions
### Future Research Directions
For example, research in this area could consider developing AI-controlled robotic systems for on-site 3 DP and the assembly of large-scale structures. * **Exploration of AI systems that offer real-time feedback and adaptation during the 3 DP process. ** As addressed in the literature, the effectiveness and quality of printed structures could be increased by integrating AI systems that offer real-time feedback and adaptation during the 3 DP process. Further research in this area could focus on developing AI models that monitor and adjust printing parameters based on real-time sensor data, ensuring accurate fabrication and reducing errors. Also, large-scale AM quality monitoring and inspection have not been as thoroughly studied [67]. * **AI-driven approaches to circular economy concepts and sustainable design of 3 DP-printed architectural structures. ** This involves exploring how AI may help with material selection, waste reduction, and life cycle evaluation to create buildings that are more resource- and environmentally friendly. On the other hand, as 3 DP architectural structures become more prevalent, it is important to study the legal and regulatory implications of their design, fabrication, and implementation [52]. In this respect, research could focus on understanding intellectual property rights, liability issues, building codes, and safety standards for AI-driven 3 DP in architecture. Moreover, future research could examine the policy and industry implications of adopting AI and AM technologies in the architectural sector. It is necessary to discuss further regulatory challenges, standards, economic issues, and potential implementation impediments. In conclusion, future research should emphasize interdisciplinary collaboration between architects, engineers, material scientists, computer scientists, and other experts. Such collaborations could facilitate a holistic approach to AI-driven 3 DP, leading to more integrated and innovative architectural solutions. As AI and 3 DP technologies continue to evolve, these research directions will play a crucial role in shaping the future of architectural design and construction practice.
