  "id": "MLC-T-ADM-000063",
  "term": "Caking",
  "field": "Additive manufacturing and 3D printing",
  "definition": "Powder that has stuck together into clumps lodged on the surface of a part or inside its holes, pockets and channels after a powder bed fusion or binder jetting build. It resists the brushing and compressed air that remove loose powder, so it adds time and care to depowdering. Media blasting is a common way to clear caked powder from polymer parts.",
