1. A three dimensional modelling system comprising:

  • means for providing coordinate information with respect to a three-dimensional element;

    workstation means arranged to receive the coordinate information from the providing means and to manipulate the coordinate information; and

    ,means responsive to manipulated coordinate information for automatically providing a three-dimensional model of said three-dimensional element by sequentially irradiating a plurality of layers of a first material which is solidifiable in response to such irradiation and including means for adding to each layer of said first material, subsequent to irradiation thereof, a second material which is not solidifiable in response to such irradiation to serve as a support material, prior to irradiation of a subsequent layer of said first material.
