Granular materials binding

  "id": "MLC-T-ADM-000159",
  "term": "Granular materials binding",
  "field": "Additive manufacturing and 3D printing",
  "definition": "A category of additive manufacturing processes that selectively joins particles of a granular material, such as polymer, sand, or metal powder, to form a solid object layer by layer. A binding agent is selectively deposited onto a bed of powder to fuse the particles together, or a thermal energy source like a laser or electron beam melts the particles. Binder jetting and powder bed fusion are the two main process families within this category.",
