Multi-station laser additive and subtractive machining system

The utility model discloses a multi-station laser additive and subtractive material processing system which comprises a forming chamber, an additive material laser light path system, a subtractive material laser light path system and an online monitoring system, and a plurality of fiber laser field lenses and a plurality of femtosecond laser field lenses are arranged at the top of the forming chamber. The subtractive laser light path system comprises a translation mechanism arranged at the top of the forming chamber and a femtosecond subtractive processing light path box arranged on the translation mechanism; when the online monitoring system detects that the powder bed has defects, the translation mechanism is controlled to move the femtosecond subtractive machining light path box to the position above the femtosecond laser device field lens corresponding to the defect position, and the femtosecond subtractive machining light path box is controlled to emit femtosecond laser beams to eliminate the defects.
