There is disclosed herein a method of molding an object by infiltrating a matrix material with an infiltration material, the method including providing first and second zones of respective different first and second matrix materials arranged substantially adjacent to each other in a mold, including forming a transition region between the two zones through which the composition of the material in the transition region is gradually varied from the composition of the first matrix material adjacent the first zone to the composition of the second matrix material near the second zone.

1. A method of molding downhole equipment or a component thereof by infiltrating a matrix material with an infiltration material, the method comprising: forming a mold of the downhole equipment or component thereof using a 3D printer, the mold comprising a plurality of portions of the mold, at least
1. A method of molding downhole equipment or a component thereof by infiltrating a matrix material with an infiltration material, the method comprising: forming a mold of the downhole equipment or component thereof using a 3D printer, the mold comprising a plurality of portions of the mold, at least a portion of the plurality of portions of the mold being formed with a heating element formed as a crow's foot while the mold is being formed;forming, using the 3D printer, first and second zones of respective different first and second matrix materials arranged substantially adjacent to each other in a mold;forming, using the 3D printer, a transition region between the first and second zones through which the composition of the material in the transition region is gradually varied from the composition of the first matrix material adjacent the first zone to the composition of the second matrix material near the second zone;heating the matrix materials in the first and second zones and the transition region using the crow's foot;infiltrating the matrix materials in the first and second zones and the transition region with a molten infiltration material to form an infiltrated matrix material; andcooling the infiltrated matrix material to solidify the infiltration material,wherein the mold is formed while the first zone, second zone, or transition region or any combination thereof is formed. 2. The method of claim 1, wherein the first zone is adjacent to at least one surface of the object. 3. The method of claim 1, wherein the transition region is formed by layering a plurality of layers of matrix material one on top of the other and by using a mixture of the first and second matrix materials in each layer and varying the composition of the mixture printed in the layers of the transition region. 4. The method of claim 1, wherein the crow's foot formed comprises electromagnetically excitable material that, when excited, will act as a heat source for heating the matrix materials. 5. The method of claim 1, wherein at least one portion of the plurality of portions of the mold has a different thermal conductivity or electrical conductivity than another portion of the mold. 6. The method of claim 1, wherein the mold comprises a mold cavity that comprises a displacement, also formed using a 3D printer. 7. The method of claim 1, wherein the crow's foot is formed of complex, non-linear shapes. 8. The method of claim 1, comprising cooling the infiltrated matrix material to solidify the infiltration material using the crow's foot. 9. The method of claim 1, further comprising heating the matrix materials in the first and second zones and the transition region using an external heat source. 10. The method of claim 1, further comprising placing the mold in a container to form a mold assembly, wherein the mold assembly further comprises an external heat source. 11. The method of claim 6, further comprising placing the mold in a container to form a mold assembly, wherein the displacement is between the mold and the container and wherein the displacement further comprises a heating element formed while the mold is being formed. 12. The method of claim 1, further comprising placing the mold in a container to form a mold assembly, wherein the container comprises a heating element. 13. The method of claim 1, further comprising placing the mold in a container to form a mold assembly, wherein the mold assembly comprises a heater in a bottom portion thereof.
