The present invention is a granular material that can be well recoated regardless of the type of the granular material, and enables a refractory aggregate in an unprinted portion to be used without any regeneration process, in the manufacture of a three-dimensional laminated and shaped mold. This granular material is a granular material for use in three-dimensional laminated mold shaping, and obtained by adding a material that causes a hydration reaction having a moisture absorbing function and generates a catalytic effect to a coating material mixed with or coated with an acid as a catalyst which activates and hardens an organic binder for binding the granular material.

A blade made of layered material, such as composite material, configured for exposure to a fluid flow, comprises skins (1, 2) defined between a leading edge (3) and a trailing edge (4) which skins in cross-section form a flow profile. The layered material may consist of several layers of fiber material (5, 5, . . . ) impregnated with a matrix material, wherein layers of fiber material each comprise a respective body portion (6, 6, . . . , 13) between and transverse to the skins and each at least a respective skin portion (7, 7, . . . ; 8, 8, . . . ) that forms part of the skins. The said skin portions all extend from the related body portion in the direction of the trailing edge. Of said skin portions at least two consecutive skin portions of the one skin overlap and/or two consecutive skin portions of the other skin overlap each other.

A plasticizing device that plasticizes a material to produce a molten material includes a driving motor, a screw that has a grooved surface on which a groove is formed and rotates by the driving motor; and a barrel having a facing surface that faces the grooved surface and has a communication hole formed in the center and a heater, wherein the screw has a cooling medium flow path provided inside the screw, an inlet portion that communicates with the cooling medium flow path and introduces a cooling medium from the outside of the screw, and an outlet portion that communicates with the cooling medium flow path and discharges the cooling medium to the outside of the screw.

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.
