Abstract: In an example of a three-dimensional (3D) printing method, a ceramic build material is applied. A liquid functional material, including an anionically stabilized susceptor material, is applied to at least a portion of the ceramic build material. A sintering aid/fixer fluid, including a cationically stabilized amphoteric alumina particulate material, is applied to the at least the portion of the ceramic build material. The applied anionically stabilized susceptor material and the applied cationically stabilized amphoteric alumina particulate material react to immobilize the anionically stabilized susceptor material, thereby patterning the at least the portion of the ceramic build material.
