This invention relates to the field of ceramic manufacturing technology and discloses a highly efficient three-dimensional underglaze ceramic manufacturing process, comprising: applying a base glaze layer containing calcium oxide to the surface of the body; applying a painting material containing bimodal magnesium oxide to the surface of the base glaze layer to construct a three-dimensional texture layer; utilizing the initial eutectic liquid phase generated at the interface during the firing heating stage as an ion diffusion channel to drive calcium ions and magnesium ions to undergo bidirectional cross-interface penetration, forming a diopside crystal phase supersaturation zone at the contact interface; and constructing a structural support framework by in-situ precipitation of needle-like crystals. This invention utilizes the mechanical constraint of the crystal framework to limit the displacement of the glaze layer in the molten state, fix the three-dimensional shape, and, together with the porous framework network generated by in-situ crystallization at the interface, alleviates the thermal expansion mismatch stress and eliminates the risk of cracking at the root of the three-dimensional texture.
