  "id": "MLC-T-ADM-000440",
  "term": "Heat deflection",
  "field": "Additive manufacturing and 3D printing",
  "definition": "The temperature at which a polymer specimen deforms under a specified load, indicating its resistance to softening at elevated temperatures. This property is measured by applying a three-point bending load to a standard test bar while increasing the temperature. The heat deflection temperature is a key characteristic for selecting materials for high-temperature additive manufacturing applications.",
