    - - Do you have some questions about the urtra-thin firms? thermal dynamic
    - - have you talk to Patrick Grant?
      - other question?
- - - - Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer.
