The method claim 1, wherein: the first, second, fifth, sixth, and seventh core material boards are disposed in a row prior to positioning the generally flat subassembly in a vacuum chamber. 3. The method of claim 2, wherein: the third and fourth core material boards are positioned on opposite sides of the row prior to positioning the generally flat subassembly in a vacuum chamber. 4. The method of claim 3, including: foldably interconnecting the first and second core material boards along a first fold line;foldably interconnecting the second and fifth core material boards along a second fold line that is generally parallel to the first fold line;foldably interconnecting the fifth and sixth core material boards along a third fold line that is generally parallel to the first and second fold lines; andfoldably interconnecting the sixth and seventh core material boards along a fourth fold line that is generally parallel to the first, second, and third fold lines. 5. The method of claim 4, including: foldably interconnecting the fifth and third core material boards along a fifth fold line that is transverse relative to the third fold line; andfoldably interconnecting the fifth and fourth core material boards along a sixth fold line that is transverse relative to the third fold line. 6. The method of claim 5, wherein: the first, second, third, fourth, fifth, and sixth fold lines comprise V-shaped grooves formed in edge portions of the core material boards. 7. The method of claim 6, wherein: the first, second, third, fourth, fifth, sixth, and seventh core material boards are formed from a single piece of core material board by pressing a V-shaped forming tool into the single pieces of core material board to form V-shaped grooves defining the fold lines. 8. The method of claim 1, wherein: the opening through the sixth core material board comprises an elongated U-shaped slot having an open edge portion that opens along a side edge of the sixth core material board prior to folding the core material boards to form the three dimensional vacuum insulated structure. 9. The method of claim 8, wherein: folding the core material boards includes positioning an edge of either the third or fourth core material boards such that it extends across the open edge portion of the elongated U-shaped slot. 10. The method of claim 1, wherein: the opening through the sixth core material board comprises a generally circular aperture through the sixth core material board. 11. The method of claim 1, wherein: folding the core material boards includes positioning the fifth core material board at a right angle relative to the sixth core material board and positioning the seventh core material board at a right angle relative to the sixth core material board. 12. The method of claim 11, wherein: folding the core material boards includes positioning the third and fourth core material boards transversely relative to the fifth core material board. 13. The method of claim 12, wherein: folding the core material boards includes positioning the second core material board at an angle in a range of about one hundred and ten degrees to about one hundred and sixty degrees relative to the first core material board. 14. The method of claim 13, including: forming an open seam between the second core material board and the third core material board that is defined by open edge portions of the second and third core material boards prior to folding the core material boards;forming an open seam between the second core material board and the fourth core material board that is defined by open edge portions of the second and fourth core material boards prior to folding the core material boards;positioning the open edge portions of the second and third core material boards directly adjacent one another by folding the second and third material boards directly adjacent one another by folding the second and third core material boards relative to the fifth core material board; andpositioning the open edge portions of the second and fourth core material boards directly adjacent one another by folding the second and fourth core material boards relative to the fifth core material board. 15. A method of making a vacuum insulated appliance door having an outwardly opening dispensing cavity for dispensing ice and/or liquid water, the method comprising: providing a plurality of core material boards;positioning the plurality of core material boards in an envelope defining an inside and having at least one opening to the inside, the envelope comprising substantially impermeable barrier material, whereby the core material boards and the envelope form a generally flat subassembly;foldably interconnecting each core material board to at least one adjacent core material board along a fold line;forming a vacuum around the generally flat subassembly in a vacuum to evacuate the inside of the envelope;sealing the at least one opening of the envelope;folding the core material boards relative to one another to form a three dimensional vacuum insulated structure having a dispensing cavity with an opening and five sides defined by core material boards, the three dimensional vacuum insulated structure further including upright lower and upper portions below and above, respectively, the opening of the dispensing cavity;positioning the three dimensional vacuum insulated structure between a door liner and an outer door skin;forming an access opening through at least one of the core material boards, defining the dispensing cavity; andpositioning the dispensing unit that dispenses at least ice and/or liquid water above the dispensing cavity whereby ice and/or liquid water from the dispensing unit travels through the access opening into the dispensing cavity. 16.
