Laser Additive Manufacturing （LAM） provides a high degree of design freedom and manufacturing flexibility for the preparation of complex metal parts in aerospace engineering， but current mainstream LAM technologies have key problems such as difficulty in monitoring and control， thermal stress deformation， and defects management. while additive manufacturing + X hybrid technology provide multi-scale solutions， and by combining the advantages of various auxiliary manufacturing processes， the accuracy and performance of AM forming materials are improved. AM + mechanical/magnetic/acoustic/thermal field enable achieve synergistic optimization of beneficial effects such as controlling melt pool flow， improving microstructure， management grain size orientation， releasing residual stress， and improving surface quality. The development of mainstream LAM technology and the current application status in the aerospace industry are reviewed， the action mechanism of additive-subtractive and additive-equivalent hybrid manufacturing technologies on LAM are summarized， and the mechanism and simulation research of non-contact magnetic， acoustic， and thermal auxiliary fields on melt pool dynamics， microstructure development， surface quality development， thermal gradient are emphatically commented. In conclusion， the strengths and limitations of various field auxiliary additive manufacturing technologies are summarized， and the future trends of laser-metal additive manufacturing + X hybrid technology are anticipated.
