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 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.

2 . The method of claim 1 , wherein successively depositing comprises:
depositing a first layer on a substrate, the first layer having a first material composition; depositing multiple sequential layers at least partially adjacent the first layer, at least a portion of each of the multiple sequential layers having the same material composition as adjacent portions of adjacent layers; and providing at least one binder to bind the first layer and multiple sequential layers.

3 . The method of claim 2 , further comprising heating the component to remove one or more of the at least one binder.

4 . The method of claim 2 , further comprising removing one or more of the at least one binder by chemical decomposition.

5 . The method of claim 2 , wherein the first layer further includes a second composition, where the first composition and the second composition form distinct regions of the first layer.

6 . The method of claim 1 , where the one or more materials are selected from the group consisting of a ceramic material, minerals, graphite, a thermally insulating material, electrically conductive materials and a friction material.

7 . The method of claim 1 , wherein the plurality of volumes are deposited through one or more nozzles of the deposition device.

8 . The method of claim 1 , wherein the body has a receiving cavity opening to at least one outer surface of the body.

9 . The method of claim 1 , wherein the body comprises:
at least two discrete regions, a first region comprising a thermally insulating material and a second region comprising a gasketing material; and at least one current path extending through the first region and the second region, the at least one current path comprising a conductive material.

10 . The method of claim 1 , wherein the deposition device has more than one nozzle, each nozzle depositing a different material in varying amounts to form the varied material property of the body.

11 . A container for use in a high pressure press, comprising:
a body having a height measured along a central axis; and a receiving cavity opening to at least one outer surface of the body; where the body has a density that is uniform along the entire height of the body and varies along a direction transverse to central axis.

12 . The container of claim 11 , wherein at least a portion of the receiving cavity has a spherical shape.

13 . The container of claim 11 , wherein the receiving cavity is a through-hole having two openings on opposite outer surfaces of the body.

14 . The container of claim 11 , wherein the at least one material has a continuously decreasing density along the direction from the central axis towards an outer surface.

15 . The container of claim 11 , further comprising a second material forming at least part of an inner wall of the receiving cavity, the second material having a density greater than the at least one material.

16 . The container of claim 11 , wherein the body has at least two regions, each region having at least one property difference therebetween.

17 . The container of claim 16 , wherein the at least two regions have mating and interlacing geometries.

18 . The container of claim 11 , wherein the body has at least one region having a material property that varies continuously in one or more directions.

19 . A component for use in a high pressure press, comprising:
a body having at least two discrete regions, a first region comprising a first material and a second region comprising a second material, where the first material and the second material have at least one property difference there between; and at least one current path extending in multiple directions through the first region and the second region, the at least one current path comprising a conductive material.

20 . The component of claim 20 , wherein the first material is a thermally insulating material and the second material is a gasketing material.
