Pulsed 3D Printing Produces Meter-Long Single Crystals for Extreme Heat
Materials researchers in China have invented a pulsed additive manufacturing process capable of growing titanium-alloy rods more than a meter tall out of a single continuous crystal. Reported in Nature, the technique eliminates microscopic grain boundaries that typically weaken metallic parts subjected to severe mechanical stress and elevated temperatures. The metallurgical invention offers an alternative route to producing components for reactors, aerospace structures, and optical systems without conventional mold-based limitations.
