Drone-3D printing linkage for rapid construction of sustainable post-disaster temporary shelters

In order to improve the response speed and structural stability of post-disaster temporary shelter construction, a rapid construction technology based on UAV-3D printing linkage is proposed. An air-ground collaborative architecture is constructed to achieve precise construction through SLAM modeling, BIM optimization engine and dynamic path planning, and highly rheological bio-based composites are used to optimize deposition precision and interlayer bond strength. We analyze the intelligent scheduling, real-time path optimization and environmental adaptability of the UAV swarm, and verify the construction accuracy, construction efficiency and material performance under different working conditions. The results show that the technology can efficiently construct a low-energy, high-strength temporary shelter structure in complex terrain environments, with a 45% reduction in carbon emission compared with traditional methods, and the energy consumption per unit area of construction is controlled within 0.8kWh/m², and the construction of 200m² shelter is completed within 72 hours. Combined with multimodal sensing monitoring and intelligent control algorithms, it can further enhance the autonomy and sustainability of disaster emergency construction.
