Research on the Rapid Prototyping Design and Optimization of 3D-Printed UAVs for Disaster Relief and Search-and-Rescue

Abstract

Natural disasters threaten the escalating threat of human security and infrastructure, highlighting the urgent need for efficient and adaptive rescue technologies. Unmanned aerial vehicles (UAVs) have become important tools for disaster response, but their extensive deployment is often limited by traditional manufacturing, such as long-term production cycles and high levels. This study studies the integration of manufacturing (3D printing) in rapid forming and optimization. Through the evaluation of the main printing process, including the Fused Deposition Modeling (FDM), Stereolithography (SLA) and Selective Laser Sintering (SLS) -- the study assessed their applicability to the lightweight, modular and task specific UAV components. The case studies on folding-wing and amphibious avs show how 3d printing can be quickly customized and functional, and structural optimization methods, such as a lattice infill and composite cement, help reduce the mechanical ability of 20-30% and enhanced. Despite the challenges associated with material durability and production scalability, additive manufacturing provides a promising way to respond with responsive, resilient, and cost-effective uav solutions.
