Publication number: 20110042859Abstract: 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 a first liquid, applying a second liquid to the first liquid layer in a pattern corresponding to the digital model, and repeating these steps to form successive layers. The first liquid comprises a first active component and the second liquid includes a second active component capable of reacting with the first reactive component so that the article is built up in layers.Type: ApplicationFiled: November 2, 2010Publication date: February 24, 2011Applicant: Huntsman Advanced Materials Americas LLCInventors: Ranjana Patel, Richard J. Peace

Publication number: 20040038009Abstract: The present invention provides unique material systems and methods for 3D printing of articles having enhanced strength and durability. The powder systems comprise a water-soluble crosslinkable agent, and alternatively or additionally, a strengthening component. Preferably, the crosslinkable agent is selected from the group consisting of amino resins, phenol resins, and mixed amino/phenol resins. The strengthening component melts and flows when heated, and resolidifies or cures. Preferably, the strengthening component melts, flows and cures with heat.Type: ApplicationFiled: August 21, 2002Publication date: February 26, 2004Inventors: Richard Noel Leyden, Timothy Marvin Cleary, John Xiaosan Li, Jacek Obuchowicz, Richard J.
