Drone frames, as a vital component of UAVs, must support all onboard equipment, including flight controllers, motors, GPS modules, propellers, batteries, power supplies, and gimbals. Therefore, the quality of the frame directly impacts the drone’s overall performance and safety. Through metal 3D printing technology, UAV frames can achieve lightweight, optimized structures, significantly enhancing production efficiency and reducing costs.

A fundamental goal in drone structural design is to ensure sufficient strength and rigidity to withstand various loads and environmental conditions while maintaining excellent aerodynamic performance and control. Using Selective Laser Melting (SLM) metal 3D printing, we have applied topology optimization to achieve lightweight and optimized structures for the drone frame. This advancement not only improves flight efficiency and stability but also extends battery life, which is critical for performing long-duration, complex tasks.

With metal 3D printing, drone frames can be manufactured directly as a single integrated structure without the need for molds. This approach allows multiple frame parts to be combined into a cohesive structure, reducing the number of components, shortening manufacturing steps and timelines, lowering quality risks, and greatly enhancing the frame’s overall reliability. The streamlined transition from design to final product significantly shortens the R&D cycle, accelerates product iteration, and reduces production costs.

Metal 3D printing offers designers complete creative freedom, enabling quick prototyping and production of complex designs, as well as the customization of intricate structures and personalized, diverse products. This flexibility allows drones to adapt rapidly to specific requirements, such as operations in specialized environments or custom payload needs.

Aluminum alloys, known for their light weight, high stiffness, strength, corrosion resistance, fatigue resistance, machining properties, and cost-effectiveness, have become a primary material for drone frames. Unlike traditional subtractive manufacturing processes, metal 3D printing, as a near-net shape technology, generates almost no waste. The modular, fully automated closed-loop powder recycling system efficiently integrates powder collection, sieving, feeding, and discharging functions, ensuring powder quality while enabling efficient aluminum alloy material reuse, which significantly boosts productivity and lowers manufacturing costs.

Extensive testing has confirmed that the drone frame meets all requirements, including structural and weight integrity, design and layout, strength and rigidity, signal transmission, thrust-to-weight ratio, and flight time.

As additive manufacturing technology continues to advance and its applications expand, metal 3D printing is fostering a deep integration between the manufacturing and drone industries, poised to play a crucial role in promoting the low-altitude economy and, by extension, broader economic development.
