Abstract
A process for forming a three-dimensional article in sequential layers in accordance with a digital model of the article. The process comprises the steps of defining a layer of powder material, applying a liquid reagent to the powder layer in a pattern corresponding to the digital model, and repeating these steps to form successive layers. The powder comprises a first reactive component and the liquid includes a second active component capable of reacting with the first reactive component so that the article is built up in layers.
