Abstract

A method of manufacturing a component for use in a high pressure press includes successively depositing a volume of one or more materials using a deposition device to build a three dimensional body of the component having a selected material property varied along at least one direction of the component for use in the high pressure press.

First claim

What is claimed is:

1. A method of manufacturing a component for use in a high pressure press, the method comprising:
successively depositing a volume of a thermally insulating material using a deposition device to build a first region of a three dimensional body of the component extending from a bottom surface of the component to a non-planar interface;
successively depositing a volume of a gasketing material using the deposition device to build a second region of the three dimensional body extending from the non-planar interface to a top surface of the component, the top surface being at an opposite axial end from the bottom surface of the component,
wherein the gasketing material is selected from clay minerals and phyllosilicates; and
wherein the first region and the second region are two discrete regions having the non-planar interface therebetween; and

successively depositing a volume of a conductive material using the deposition device to build at least one current path extending through the first region and the second region, from the top surface of the component to the bottom surface of the component, that transverses the non-planar interface.

2. The method of claim 1 , wherein the at least one current path extends through the first region and the second region in multiple directions between the top surface of the component and the bottom surface of the component.

3. A method of manufacturing a component for use in a high pressure press, the method comprising:
successively depositing multiple sequential layers of a gasketing material using a deposition device to build a first region of a three dimensional body of the component;
wherein the first region forms at least one outer surface of the component and a portion of an inner wall defining a receiving cavity extending through the component; and
wherein the gasketing material is selected from clay minerals and phyllosilicates; and

using the deposition device to deposit the gasketing material and a second material in distinct portions of multiple sequential compound layers to build a second region of the three dimensional body surrounded by the first region, such that the second region at least partially mates with and fits within a corresponding recessed geometry of the first region;
wherein the second material is different from the gasketing material;
wherein the second region forms a remaining portion of the inner wall of the receiving cavity; and
wherein the second region has a gradually decreasing thickness along the inner wall from an axially central region of the receiving cavity towards axial ends of the receiving cavity.

4. The method of claim 3 , wherein the second material is a thermally insulating material.

5. The method of claim 3 , wherein the second material is graphite.

6. A method of manufacturing a component of a high pressure press, comprising:
depositing a first layer on a substrate, the first layer having a first material composition comprising a gasketing material selected from clay minerals and phyllosilicates;
depositing multiple sequential layers comprising at least one of the first material composition and a second material composition at least partially adjacent the first layer to build a three dimensional body of the component, comprising:
a first region formed of the first material composition;
a second region formed of the second material composition; and
a receiving cavity formed through the first region and the second region, such that the first region and the second region form portions of an inner wall defining the receiving cavity,
wherein the receiving cavity has a uniform diameter along an entire height of the receiving cavity; and

providing at least one binder to bind the first layer and multiple sequential layers.

7. The method of claim 6 , further comprising heating the component to remove one or more of the at least one binder.

8. The method of claim 6 , further comprising removing one or more of the at least one binder by chemical decomposition.

9. The method of claim 6 , wherein the second region is inlaid within the first region.

10. The method of claim 3 , wherein the receiving cavity has a geometry comprising a spherical shaped portion.
