7075 aluminium is a typical high-strength aluminium alloy for aerospace applications. Unfortunately, 7075 aluminium is incompatible with additive manufacturing owing to severe hot cracking tendency, which hinders the fabrication of complex-geometry parts of 7075 aluminium via additive manufacturing. Our newly developed 7075 aluminium alloy powders have been reliably used on various types of selective laser melting equipment (e.g., Bright Laser Technologies BLT-S310, E-Plus-3D EP-M260), with micro-cracks completely suppressed. The as-printed sample exhibits a tensile yield strength of 445-470 MPa, an ultimate tensile strength of 475-500 MPa, and an elongation of 14-18%. The heat-treated sample exhibits a tensile yield strength of 520-540 MPa, an ultimate tensile strength of 545-575 MPa, and an elongation of 7-9%.
