Hiroshima University. This technique tempers the metal instead of liquefying it and generating overheating problems, bringing the material to a state where it can be bonded without compromising its integrity. With the high costs of tungsten and cobalt, this method will yield better results and can be likened to metal 3D printing, matched to the layer-by-layer fabrication approach.
This could represent a pivotal shift not only for tool production but also for future advancements in 3D printing. Hot-wire laser irradiation merges a laser with a pre-warmed wire, allowing for material addition while maintaining strict heat control. Researchers investigated two building techniques, with the careful execution being crucial, as one would anticipate for such a complex procedure.
