Luminescent and scintillation ceramic materials with complex shapes, which can be created by stereolithography 3D printing, are of interest for special phosphor detector applications. Starting powders such ceramics may possess UV absorption bands; therefore, it is important to study the possible influence powders’ luminescent properties on printing process. This paper deals garnet oxides, Y3Al5O12 Gd3Al2Ga3O12—well-known hosts materials. The photopolymerization rates slurries based produced various chemical routes studied, as well available regimes. containing Ce-doped a broad band in have significantly lower compared undoped ones; high Ce doping virtually hinders layers thicker than 25–50 μm. Furthermore, choice powder synthesis method shown Slurries Tb-doped powder, lines at shorter wavelengths, good activity, close that printed layer thicknesses 25–100
