1. A method of producing a three-dimensional object from a liquid medium by forming first and second cross-sectional layers of structure of said object at a surface of said liquid medium, said method comprising the steps of:

  • providing a body of said liquid medium;

    forming said first cross-sectional layer of structure of said object at said surface of said liquid medium;

    coating said first cross-sectional layer of structure of said object with a layer said liquid medium having a desired thickness, said coating step including the steps of;

    firstly, positioning said first cross-sectional layer of structure into said liquid medium at a depth greater than said desired thickness; and

    secondly, positioning said first cross-sectional layer of structure at a depth equal to said desired thickness;

    forming said second cross-sectional layer of structure of said object at said surface of said liquid medium to build up said three-dimensional object.
