Embodiment Construction
[0029] The equipment of the present invention mainly includes a vacuum chamber (100), a working table (101), a feeding device (109), a multi-wavelength fiber laser (120), a real-time monitoring system (110) and a control center. See figure 1 , the working table (101), feeding device (109), multi-wavelength fiber laser (120), and real-time monitoring system (110) are all located in the vacuum chamber (100), and the multi-wavelength fiber laser (120) and real-time monitoring system ( 110) is also connected with the control center outside the vacuum chamber (100). The workbench (101) is provided with a cooling liquid circulation pipe (111), through which the cooling liquid is used to cool the molded product (102). In practice, the cooling liquid can be water or liquid nitrogen. The feeding device (109) is used to supply raw materials to the workbench (101).
[0030] The multi-wavelength fiber laser (120) integrates a nanosecond laser probe (106), a picosecond laser probe (107) ...
