Significant Breakthrough at Northwestern Polytechnical University: 3D Printed Aluminum Alloy Achieves Dual Breakthrough in Strength and Toughness, Impact Toughness Increases by 76.9%

Significant Breakthrough at Northwestern Polytechnical University: 3D Printed Aluminum Alloy Achieves Dual Breakthrough in Strength and Toughness, Impact Toughness Increases by 76.9%

In simple terms, 3D printed aluminum alloy parts are prone to cracking under sudden impact, making them not “sturdy” enough. Researchers found that changing the laser scanning method during printing—re-melting each layer at a faster speed and higher power after printing—can refine and homogenize the metal grains inside the parts, effectively weaving a stronger “net” … Read more
