Product Features: 1. 1940nm precise matching of polymer, ceramic, and ferrous metal absorption spectra, with high material coupling efficiency. 2. Continuous output with ≤±2% fluctuation, controllable molten pool, and good molding repeatability. 3. Excellent focusing performance, microstructures, and high precision in forming thin-walled parts. 4. No external optical components, vibration-resistant, dustproof, maintenance-free, easy equipment integration and multi-optical parallel connection. 5. The wavelength is located at the water absorption peaks of various polymer materials and specialty plastics, enabling efficient and clean melting and sintering, making it an ideal light source for SLS printing of materials such as nylon and TPU.
