1. A process for forming a three-dimensional article in sequential layers in accordance with a model of the article, the process comprising the steps of:

  • defining a continuous layer of a first liquid material;

    applying a second liquid to locations of the first liquid layer in a pattern corresponding to the model; and

    repeating these steps to form successive layers; and

    in which the first liquid includes a first active component and the second liquid includes a second active component which is capable of reacting with the first reactive component so that the first layer cures in locations to which the second liquid has been applied but does not cure in the locations to which the second liquid has not been applied, the second liquid having a viscosity in the range of 2 to 500 cps at room temperature and wherein the first liquid and/or the second liquid further comprise nanoparticles.
