The development of the stereolithography technique for additive manufacturing silica glass has brought revolutionary change in manufacturing. Here, we demonstrate fabrication 3D luminescent transparent parts manufactured by stereolithographic together with solution impregnation and high temperature sintering. Prefabricated nanopores were prepared debinded pre-sintered at first. To functionalize photoluminescence, Eu3+, Tb3+ Ce3+ ions doped a method further sintered temperature. photoluminescence from these rare earth blue, cyan red spectral region can be facilely generated illumination 254 nm UV lamp. Furthermore, developed space-selective doping that enables different fashion, resulting multicolor object giving distinguishable luminescence each part.
