The invention relates to the technical field of additive manufacturing, and discloses a metal selective laser melting forming method and system. The metal selective laser melting forming system comprises a regional light spot light path system, a Gaussian light spot light path system and a terminal controller. The metal selective laser melting forming method comprises the steps that a terminal controller obtains a three-dimensional digital model of a to-be-formed part; the terminal controller performs hierarchical slicing on the three-dimensional digital model of the part to obtain hierarchical slicing data; acquiring a printing mode of the part, and performing path planning to obtain laser scanning path planning data; and controlling the regional light spot light path system or controlling the regional light spot light path system and the Gaussian light spot light path system to print the part based on the laser scanning path planning data. The selective laser melting forming system is simple in structure and easy to control, the carrying area light spot mixing light path system improves the manufacturing efficiency of large-section formed parts, and the manufacturing cost of multi-laser equipment machining is reduced.
Description
technical field [0001] The invention relates to the field of additive manufacturing, in particular to a metal selective laser melting forming method and system. Background technique [0002] Additive manufacturing, commonly known as 3D printing, integrates computer-aided design, material processing and forming technology, and is based on digital model files. Sintering, melting, light curing, spraying and other methods are stacked layer by layer to create a manufacturing technology for physical objects. Laser 3D printing technology, including Selective Laser Melting (SLM) technology and Selective Laser Sintering (SLS) technology, is the main method of additive manufacturing using metal materials and some non-metal materials as raw materials. The selective laser melting technology is based on the general principle of rapid prototyping, and uses software to build a three-dimensional solid model of the part, and then according to specific process requirements, the three-dimensi...
