Rock stars are known for smashing guitars—but what happens when they encounter an unbreakable one? Engineering group Sandvik partnered with Swedish guitarist Yngwie Malmsteen to test the limits of a smash-proof guitar.
Additive manufacturing of glass is still a ways from industrial capacity, but research in this field is gaining steam. Two recently published papers detail two ways to 3D print glass—laser powder bed fusion, and fused filament fabrication.
Researchers at North Carolina State University (Raleigh, N.C.) have now broken the critical casting thickness—the previous maximum possible size—for fabricating bulk metallic glass by using laser-based powder bed additive manufacturing.
