Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a laser additive manufacturing equipment and method for manufacturing large metal components. Background technique [0002] Laser additive manufacturing technology uses high-power lasers to quickly melt / solidify layer by layer to achieve direct near-net shape manufacturing from digital 3D models of parts to fully dense, high-performance large-scale complex metal structures. Titanium alloy has excellent specific strength and corrosion resistance. Since the middle of last century, it has gradually been used in the aviation industry. At present, it has replaced a large number of steel, aluminum alloy and other materials, and occupies an important position in aerospace metal materials. Due to the high laser absorption rate of titanium alloy, it has good adaptability to laser additive manufacturing technology. Compared with components manufactured by traditional methods, titaniu...
