The invention discloses a gas phase diffusion/reaction laser metal 3D printing system. The gas phase diffusion/reaction laser metal 3D printing system comprises a laser selective melting forming device, and further comprises a ventilation device. The ventilation device comprises a gas storage tank, a gas pipe and a nozzle. The gas pipe is installed on the gas storage tank. The nozzle is fixedly installed on a laser head of the laser selective melting forming device. A vertically-through laser through hole is formed in the nozzle so that laser beams transmitted by the laser head penetrate the nozzle from the laser through hole. A vertically-through vent hole is further formed in the nozzle so that gas flowing in the gas pipe can penetrate the nozzle from the vent hole, and therefore the gas can be sprayed to the portion, needing chemical thermal treatment, on a part. According to the gas phase diffusion/reaction laser metal 3D printing system, the part of a complex structure can be manufactured, modification of any region in the part can be achieved, for example, nitridation/carbon enhancement and oxide dispersion enhancement, and the performance design of the part can be achieved while the structure complexity is achieved.
