The physical structure of the solar array was meticulously replicated, encompassing the layout of the solar panel segments, the supporting framework, and the folding and unfolding mechanisms—ensuring high fidelity to the real spacecraft. This enabled a successful simulation of the intelligent control system responsible for deploying and retracting the solar arrays in the vacuum of space. The team’s solar array model not only meets stringent technical standards but also plays a vital role in education and public outreach, offering a vivid and engaging example that helps the general public better understand aerospace technology.

Core 3D Printing Requirements
Material: White, high‑toughness PLA
Key Parameters: Layer height 0.2 mm, infill density 25%, nozzle temperature 200°C, heated bed temperature 55°C
Special Treatments: Fine, intricate features should be printed at a lower layer height of 0.15 mm using a slow print speed; sealing surfaces must be carefully sanded and then reinforced with adhesive.
