The invention provides an additive manufacturing monitoring system and electron beam selective melting additive manufacturing equipment, and relates to the technical field of additive manufacturing. The additive manufacturing monitoring system comprises an image collection device, an illumination device and a rotating disc. The rotating disc is connected to a vacuum chamber, a first through hole and second through holes spaced are formed in the rotating disc, and the first through hole is formed in the center of the rotating disc. An electron beam penetrates through the first through hole to irradiate a preset area. The rotating disc rotates relative to the vacuum chamber to make the second through holes correspond to the illumination device or the image collection device, illumination light can penetrate through the second through holes to irradiate the preset area, and the image collection device is used for collecting an image of the preset area through the second through holes. Theinvention further provides the electron beam selective melting additive manufacturing equipment. Through the additive manufacturing monitoring system and the electron beam selective melting additivemanufacturing equipment provided by the invention, an observation lens can be effectively protected against being polluted by metal vapor, the additive manufacturing process can be monitored in real time for a long time, and the maintenance cost can be lowered.
Description
technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an additive manufacturing monitoring system and electron beam selective melting additive manufacturing equipment. Background technique [0002] Additive manufacturing is a combination of computer-aided design, material processing and forming technology, based on digital model files, through software and numerical control system, special metal materials, non-metal materials and medical materials, according to extrusion, sintering, melting, light Solidification, spraying, etc. are accumulated layer by layer, and the manufacturing technology of directly manufacturing physical objects. Electron beam selective melting additive manufacturing refers to the powder bed additive manufacturing technology that uses electron beams as heat sources. It has the advantages of high energy utilization, no reflection, high power density, fast scanning speed, and no pollution in vacuum...
