CA 2438537

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.

L'invention concerne un procédé de formation d'un article tridimensionnel en couches successives, conformément à un modèle numérique de l'article. Le procédé consiste à mettre en place une couche d'une matière poudreuse; à appliquer un réactif liquide sur la couche de poudre selon une configuration correspondante au modèle numérique; et à répéter ces étapes pour former des couches successives. La poudre comprend un premier élément réactif, et le liquide comprend un second élément actif pouvant réagir au contact du premier élément réactif de façon à constituer l'article en couches.
