Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and more specifically relates to a gas phase diffusion / reaction laser metal 3D printing method and a system thereof. Background technique [0002] Laser 3D printing technology is based on the principle of layer-by-layer manufacturing, which uses high-energy laser beams as energy to melt metal powder and accumulate layer by layer into complex three-dimensional part structures. This technology transforms complex three-dimensional processing into simple two-dimensional processing, which greatly reduces the difficulty of forming complex parts, and can solve the problem that traditional technology is difficult to process or cannot process complex structural parts. It has broad application prospects in many fields. [0003] At present, according to the delivery method of metal powder materials, laser 3D printing technology is mainly divided into laser near-shape manufacturing (Laser Eng...
