The most common metal material types in the current metal additive manufacturing are mainly metal powder and metal wires, and additive manufacturing technologies can be divided into powder feeding type and wire feeding type according to different material types. The powder feeding type additive manufacturing technology has relatively high molding precision and relatively quick development, but the metal powder has relatively high price, the material utilization rate is very low (20% -30%), and powder particles have certain harm to the environment and operators.

The laser wire feeding additive manufacturing technology is an additive manufacturing technology for forming metal structural parts by taking metal wires as materials and taking laser as a heat source. The system typically includes a laser, an automatic wire feed system, a numerically controlled table or a robotic system, and some auxiliary mechanism (e.g., shielding gas, preheating or cooling system), etc.

Research on the forming process (taking laser as the sole heat source) characteristics of the laser wire feeding additive manufacturing technology shows that the forming process can obtain a formed sample with excellent forming quality and no internal defects, but the laser wire feeding additive manufacturing under the technical condition of the laser wire feeding additive manufacturing also has certain limitations, such as low forming efficiency, narrow process window, unsmooth wire transition at corners and lap joint positions and the like
