Real-time monitoring rapid prototyping device and method based on femtosecond laser composite technology

The invention provides a real-time monitoring rapid prototyping device and method based on the femtosecond laser composite technology. The device comprises a vacuum chamber (100), a workbench (101), a feeding device (109), a multi-wavelength fiber laser (120), a real-time monitoring system (110) and a control center, wherein the workbench (101), the feeding device (109), the multi-wavelength fiber laser (120) and the real-time monitoring system (110) are arranged in the vacuum chamber (100), and the multi-wavelength fiber laser (120) and the real-time monitoring system (110) are further in signal connection with the control center outside the vacuum chamber (100). The novel rapid prototyping device and method are provided for manufacturing high-strength, high-finished-product-rate and complex-structure parts and are particularly suitable for various sensors higher in requirement for precision and consistency.
