Metallic glasses are noncrystalline solid metals that have high strength, excellent corrosion resistance, and impressive hardness compared to their crystalline counterparts. A modern understanding of how glasses are formed along with an appreciation for the high ultimate yield strength of metallic glasses are leading to a boon in applications for these unique materials.

The high heating and cooling rates of additive manufacturing make it a good fit for metallic glasses, whose high elasticity, strength, hardness, and corrosion resistance are used in high-performance applications such as aerospace, defense, and biomedical devices.
