Abstract
Various embodiments of the present disclosure provide an additive manufacturing method. The method includes forming a first layer of a first ceramic material and forming a second layer of a second ceramic material. The method further includes contacting the first layer of the first ceramic material, the second layer of the second ceramic material, or both with a saturant. The method further includes heating the first layer of the first ceramic material, the second layer of the second ceramic material, or both to a temperature in a range of from about 50° C. to about 300° C. The method further includes applying pressure to the first layer of the first ceramic material, the second layer of the second ceramic material, or both. The pressure can be in a range of from about 10 kPa to about 800 MPa. The method further includes at least partially dissolving a portion of an external surface of a ceramic particle of the first layer of the first ceramic material, the second layer of the second ceramic material, or both. The method further includes fusing a portion of the dissolved portion of the external surface of the ceramic particle to from a product having a density in a range of from about 65% to about 100% relative to a corresponding fully densified product and optionally containing no organic binder.
