  "id": "MLC-T-ADM-000414",
  "term": "Watertight solid",
  "field": "Additive manufacturing and 3D printing",
  "definition": "A 3D digital model where all surfaces are perfectly connected and form a completely enclosed volume without any gaps, holes, or overlapping facets. This characteristic is necessary for successful slicing and printing in additive manufacturing, as it defines a clear interior and exterior for the object. Non-watertight models often lead to errors during toolpath generation.",
