Abstract
A three dimensional article is produced layer by layer by jetting droplets of at least two different hardenable materials, as appropriate, into the various layers, the first material forming the article itself, and the second material forming a support for the article as necessary. The second material is thereafter separated from the first material, e.g., by heat, to form the desired article.
