An apparatus for three-dimensional laminating and coloring a dental ceramic crown includes a slurry layering module, a coloring module, a light curing module and a main controller. The main controller controls the slurry layering module to lay a slurry from a slurry tank to form a slurry layer, controls the coloring module to color the slurry layer with the colorant in a color tank to form a colorant layer according to a plurality of coloring parameter data, controls the light curing module to cure the slurry layer according to a plurality of laminated graphics. The apparatus may color each slurry layer, and the color can be easily changed as desired. The overall coloring effect of the dental ceramic crown is natural with good light transmittance, and the color is saturated without any blooming formed between the colored layers.
