Mini Turbofan Engine Model (A380 Engine Prototype) 3D Printed PLA Replica Overview This detailed mini turbofan engine model is based on the A380 aircraft engine as a prototype and produced using 3D printing technology. More than 150 individual components recreate the structure of a turbofan engine, and a builtin motor drives all blades to rotate at a constant speed. The model is intended as a display and learning aid only; it has no flight capability and rotation speed cannot be adjusted. Key benefits Accurate structural replica: Over 150 precision 3D printed parts replicate the internal and external features of a turbofan engine for clear visual and handson study. Demonstrates turbine operation: Motordriven blades rotate under power, helping to illustrate basic turbofan mechanics and blade arrangement. Ready to power: Runs on a simple 2xAA battery supply, making it easy to operate without special tools. Batteries are not included. Compact display piece: Lightweight and compact dimensions make it suitable for desks, shelves, classrooms, or model collections. Durable material: Constructed from PLA for stable, crisp 3D printed detail. Specifications Material: PLA Color: As shown in product images Drive mode: 2xAA battery required, not included Weight: About 238 g Size: 230 x 110 x 140 mm (9.06 x 4.33 x 5.51 inches) Package contents: 1 piece mini PLA turbofan engine model Function and limits Decorative and demonstrative only; the model does not provide propulsion and cannot fly. Blades rotate at a fixed speed driven by the onboard motor and are not adjustable. Intended for display, demonstration, teaching, or collection purposes. Suggested uses Desk or shelf display for aviation enthusiasts and model collectors. Visual teaching aid for classrooms or hobby workshops to explain basic turbofan structure and moving parts. Demonstration prop for hobbyists showing how engine blades are arranged and rotate under motor drive. Safety and handling Read the instruction manual carefully before use and be mindful of the surrounding environment when operating. Take appropriate protective measures. For experiments that involve combustion or chemical reagents, use eye protection and gloves to avoid injury or damage to clothing. Minors should use and operate the model under adult supervision. After use, store the model and any experimental equipment out of reach of children. Additional notes Please allow a 1 to 3 cm measurement variation due to manual measurement. Colors may vary slightly from images because of different display settings.
