1/18 Scale 3D Printed WS15 Functional Turbofan Engine Model Kit (50+ PCS) Product overview A detailed, functional 1 to 18 scale model of the WS15 turbofan core designed for hobbyists, collectors, and educational use. The kit uses precision 3D printed thermoplastic components and a battery driven motor to demonstrate realistic rotor motion inside a transparent housing. Key benefits See how a turbofan core works: Transparent shell and moving fan blades let you observe internal motion and basic mechanical operation. Hands on learning: Assembly reinforces mechanical skills and provides a clear demonstration tool for classrooms, clubs, or study. Durable and accurate: Custom FDM 3D printing with a tolerance of plus or minus 0.1 mm and endurance testing ensure parts fit and withstand extended use. Ready to assemble: Kit includes most parts and basic tools for immediate build, making it suitable for experienced modelers and advanced beginners aged 16 and up. Main features Scale and model: 1/18 scale representation of the WS15 turbofan core structure. Designed from non classified reference data and reviewed by aerospace industry experts for structural fidelity. Functional mechanism: Electric motor drives the fan blades for a realistic rotating display. Transparent outer shell provides full visibility of moving components. Power and run time: Battery powered with included battery. Typical run time is 30 minutes on a full charge. Construction and materials: precision thermoplastic parts produced by custom FDM 3D printing. Parts have been CFD simulated and endurance tested for over 200 hours. Tolerances and reliability: Component tolerance of plus or minus 0.1 mm to ensure accurate assembly and long term operation. Packaging and instructions: Comes in a protective box with a step by step instruction manual and a QR code for guided assembly. Packaged to be gift ready. Technical specifications Material: Thermoplastic Form: Kit version, requires assembly Power: Battery included Run time: 30 minutes with fully charged battery (battery included) Product weight: 600 g Package weight: 980 g Product dimensions: 27 x 7.8 x 10.2 cm Package dimensions: 33 x 18 x 14 cm Packing: Box Recommended age: 16 and up Package contents 3D printed turbofan engine set x1 Tools x2 Screws x several Instruction manual and QR code for guided assembly Suitable use scenarios Classroom demonstration: Use the model to illustrate basic turbofan mechanics, airflow visualization, and component relationships in engineering or aviation classes. Hobby assembly and display: Assemble and run the model as a hands on project, then display the finished engine on a shelf or desk. Design reference and study: Use the visible core and rotating parts for reference when learning about turbomachinery layout and component interaction. What makes this kit stand out Functional, visible rotor operation inside a transparent housing provides practical insight not available from static models. Precision 3D printed parts and tested endurance deliver repeatable performance and reliable assembly. Complete kit format with included tools, instructions, and battery enables immediate building and demonstration. Notes Kit requires assembly and basic mechanical skill. Recommended for ages 16 and up. The model represents core structure and mechanical motion for demonstration and educational purposes.
