  "id": "MLC-T-ADM-000348",
  "term": "Shot peening",
  "field": "Additive manufacturing and 3D printing",
  "definition": "A cold working process used to improve the fatigue life and stress corrosion cracking resistance of metal parts, including those produced by additive manufacturing. It involves bombarding the surface of a component with small, spherical media, creating compressive residual stresses. This surface treatment can mitigate microscopic defects and surface irregularities inherent in some 3D printing processes.",
