Laser technology plays an important role in the field of aerospace manufacturing. In addition to the laser acting alone on the processing process

there are various multi-energy field composite manufacturing methods based on laser technology. However

the inherent mechanisms of these composite manufacturing methods still need to be explored in depth. In response to the above challenges

the molecular dynamics (MD) method is used as a powerful tool to explore the coupling mechanism between multi-energy fields

optimize the processing parameters of composite manufacturing methods

and explore other micro-nano processing methods. This paper reviews the application of MD in multi-energy field composite manufacturing based on laser technology

and outlines the corresponding processing principles and MD simulation schemes for different composite manufacturing methods. The model design of MD simulation and the whole process of composite processing based on laser technology in different processing scenarios are discussed. In addition

this paper introduces the challenges and solutions faced in this field

and tries to determine future research directions based on existing knowledge and technology.
