C919 Civil Aviation Passenger Aircraft Model Production Guide
I. Project Background
Produce a scale C919 display model for an aviation technology company for use in air shows, technical presentations, and customer negotiations. The model must accurately reproduce the actual aircraft's exterior and details, with a realism level of over 90%.
II. Core Processes
Modular Printing: The fuselage, wings, tail, and doors are divided into independent modules for printing to ensure precise aerodynamic shapes (e.g., the curvature of the supercritical wings and winglets).
Precision Moulding: Thin-walled structures (e.g., door frames) are printed uniformly, while complex components (e.g., engine nacelles) are processed in layers to minimise support residue.
3. Material Selection
Main Structure: High-tensile resin is used to print the fuselage and wings, while rigid resin is used to create the engine nacelles.
Functional Components: Transparent resin is used for the windows, flexible resin for the hinges of the opening doors, and wear-resistant resin for the landing gear.
IV. Post-Processing
Finishing and Painting: Sanding to remove layer lines, polishing the skin; applying matte paint to metal components, painting the fuselage in aviation white, and adding blue accents to the window frames.
Detail Reproduction: Micro-engraving of serial numbers and logos, embedding LED lights to simulate navigation lights, and magnetic-mounted doors that can be opened and closed.
Dynamic Functionality: Manual opening and closing of doors, retractable landing gear, and LED light strips under the wings to simulate night lighting.
5. Delivery Standards
Smooth operation of moving parts, no lighting issues;
Even colouring, clear details (e.g., sensor windows, antennas);
