AB - Digital light processing 3D printing and pressureless sintering are combined to construct color‐tunable all‐inorganic functional composites by a simple and general strategy. The insertion of Y3Al5O12:Ce (YAG:Ce) into silica glass (YAG:Ce‐PiSG) is realized by pressureless sintering based on silica nanocomposites for 3D printing, which effectively controls the intense interface reaction between phosphor and substrate. The chromaticity of YAG:Ce‐PiSG‐based white light‐emitting diodes (WLEDs) shifts from blue‐white to white and yellow, and the 3D‐printed dome structure aids in the heat dissipation and pump blue light utilization. In addition, a series of red‐emitting color converters (CASN:Eu‐PiBSG) are synthesized by cofiring CaAlSiN3:Eu (CASN:Eu) with low softening‐point borosilicate glass powders, overcoming the fatal drawback of inherently low thermal performance. The chromaticity of integrated YAG:Ce‐PiSG/CASN:Eu‐PiBSG‐based WLEDs benefiting from 3D printing technology is adjusted in the color range from cold white to warm white. A warm WLED with high luminous efficiency (92.6 lm W−1) and excellent color rendering index (90.2) is successfully assembled. The 3D printed customizable phosphor–glass composites offer a great potential to develop high‐power and color‐tunable WLEDs, which are also of great significance for developing innovative glass composites with high‐temperature stability.
