Description

technical field [0001] The invention belongs to the field of additive manufacturing of metal materials, and in particular relates to an additive manufacturing device and a method for additive manufacturing using the device. Background technique [0002] Additive manufacturing technology is based on the three-dimensional model of the product and uses the principle of discrete stacking to realize rapid prototyping manufacturing technology. It can directly manufacture complex parts of various materials and has a wide range of industrial application prospects. However, additive manufacturing has the characteristics of high molten pool temperature, rapid solidification, and large temperature gradient, which will lead to high residual stress and metallurgical defects inside the formed workpiece, resulting in deformation, reducing mechanical properties, especially fatigue properties, and affecting Use performance. The above phenomenon is particularly prominent in the manufacturing...
