Abstract

The invention discloses an intelligent laser 3D printing device and method, and belongs to the technical fields of intelligent manufacturing and additive manufacturing. The intelligent laser 3D printing device comprises an outer shell, a semiconductor laser, a computer, a workpiece stage, a drive motor, a galvanometer X, a galvanometer Y, a scanning mirror X, a scanning mirror Y, a field lens, a molten pool and two CCD cameras; by utilization of a laser 3D imaging technology, 3D scanning imaging is performed on an entity object subjected to laser 3D printing, thereby achieving CAD modeling of the 3D entity object; and by utilization of a laser photoacoustic technology, internal defects of the entity object subjected to laser 3D printing are detected, thereby detecting the quality of the entity object subjected to laser 3D printing online in real time. According to the intelligent laser 3D printing method, the CAD modeling, rapid prototyping, and internal defect detecting functions of the entity object subjected to laser 3D printing are achieved by utilizing the same laser source, so that laser 3D printing equipment can be systematized and intelligentized. Therefore, the intelligent laser 3D printing device disclosed by the invention has the advantages of being convenient and rapid in printing, high in prototyping quality, high in intelligent degree, simple in structure, reliable in running, and the like.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing technology and additive manufacturing technology, and in particular relates to an intelligent laser 3D printing device and a printing method. Background technique [0002] Laser Rapid Prototyping (LRP) technology is one of the important means of Additive Manufacturing (AM) technology. Its basic principle is the "discrete-stack" processing technology. CAD) model is discretized, and then the process of obtaining a three-dimensional solid object by adding material layer by layer. This new manufacturing method integrates CAD / CAM (computer aided manufacturing, computer Aided Manufacturing, CAM) technology, laser and material science, reverse engineering technology, layered manufacturing technology and other technologies, breaking through the traditional subtractive manufacturing or plastic manufacturing methods Due to the constraints of tools and fixtures, product models and even finished prod...
