Abstract
A method of forming a cutting element comprises forming a first material comprising discrete coated particles within a container. The first material is pressed to form a first green structure comprising interbonded coated particles. A second material comprising additional discrete coated particles is formed over the first green structure within the container. The second material is pressed to form a second green structure comprising additional interbonded coated particles. The first green structure and the second green structure are sintered to form a multi-layered cutting table. Additional methods of forming a cutting element, a cutting element, and an earth-boring tool are also described.
