National scientists have developed a new method for 3D printing high-strength aluminum alloy

British "Nature" magazine published a new breakthrough in materials science on the 20th: American scientists have developed a new method for 3D printing high-strength aluminum alloy. At present, most of the alloys developed by the additive manufacturing method will have periodic cracks, but the new alloys have not only crack marks, but the strength is comparable to forged materials. This method can also be used in the manufacture of other alloys.
