Biomimetic manta ray toy model, designed to harness ocean current energy for power generation and to achieve low‑power, high‑efficiency underwater operations under MPF propulsion mode—environmentally friendly and energy‑efficient.

Core 3D Printing Requirements
Material: White, high‑toughness PLA
Key Parameters: Layer Height 0.2 mm, Infill Density 25%, Nozzle Temperature 200°C, Build Plate Temperature 55°C
Special Processing: Use a 0.15 mm layer height and lower print speed for intricate structural details; sealant surfaces must be carefully sanded and then reinforced with adhesive.
