Method for manufacturing dental prostheses, comprising the following operations: defining a layered numerical representation of a dental prosthesis (11)； for a first layer of the numerical representation, prepare a corresponding layer of a light sensitive liquid substance (6)； selectively solidify the layer of liquid substance (6) to obtain a first sheet (7) having a geometry corresponding to the geometry of the first layer of the numerical representation； repeat the operations of preparing a layer of liquid substance (6) and selectively solidify the layer of liquid substance (6) for each subsequent layer of the numerical representation to obtain corresponding sheets (7)； cause the mutual adhesion between said sheets (7)； modify the composition of the liquid substance (6) after having solidified one of the sheets (7) and before solidifying the subsequent sheet (7), so as to modify one or more optical properties of the liquid substance (6).
