Amit Bandyopadghyay has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Solid freeform fabrication methods
    Patent number: 5900207
    Abstract: A fused deposition process is used to form three-dimensional solid objects from a mixture including a particulate composition dispersed in a binder. The article is formed by depositing the mixture in repeated layers of predefined thickness, with each layer solidifying before the next adjacent layer is dispensed. Following formation and a binder removal step, the article may be at least partially densified to achieve preselected properties. The process permits three-dimensional articles to be formed relatively quickly and inexpensively, without the need for molds or other tooling.
    Type: Grant
    Filed: May 20, 1997
    Date of Patent: May 4, 1999
    Assignees: Rutgers, the State University Old Queens, Stratasys, Inc.
    Inventors: Stephen C. Danforth, Mukesh Agarwala, Amit Bandyopadghyay, Noshir Langrana, Vikram R. Jamalabad, Ahmad Safari, Remco van Weeren, William R. Priedeman, Jr.
