Additional Technical Notes:
- Material Applications: Aerospace sector primarily uses titanium alloys, nickel-based superalloys, and aluminum alloys. UAV/drone sector widely employs engineering plastics (ABS, PLA, Nylon) for lightweighting.
- Technical Advantages: 3D printing enables complex internal structures (par ex., cooling channels), integrated manufacturing (reducing part count and connectors), rapid design iteration, and significant weight and cost reduction.
- Limites: Large-scale applications are still constrained by material certification, printing precision, and efficiency, but the technology has become an important supplement for prototyping, small-batch customization, and high-complexity part manufacturing.
