Claim 10:
11. A method of additively manufacturing a part, the method comprising:
for each of a plurality of regions of the part, determining a thickness of the part within the region, wherein the thickness of the part within each region comprises a solid wall devoid of cavities between a first surface of the region and a second surface of the region, and the thickness is a distance between the first surface and the second surface;
depositing the binder solution within a powder bed at locations corresponding to the first surface and the second surface of each of the plurality of regions to bind powder along each of the first surface and the second surface, thereby defining a geometry of the part;
for at least one of the plurality of regions of the part, depositing the binder solution within the powder bed in a predetermined pattern at locations between the first surface and the second surface such that at least some powder between the first surface and the second surface is unbound;
removing loose powder external to the geometry of the part, thereby exposing a green body part having unbound powder contained within the geometry of the part; and
sintering the green body part to generate the part, wherein the unbound powder contained in the green body part is sintered to solidify the solid wall of the part.
