Understanding Grain Boudaries in Additive Manufacturing

Grain contingaries are the interfaces where crystals of different orientations meet with in a metal. In additive manufacturing, rapid cooling and laier -by-layer buildup often lead to complex and unstable grain compdary structures. These unstable contenzaries can cause issues such as cracking, porosity, and reduced concent.
