Inorganic scintillators are widely used for scientific,
industrial and medical applications. The development of 3D printing
with inorganic scintillators would allow the fast creation of
detector prototypes for the registration of ionizing radiation, such
as alpha, beta and gamma particles in thin layers of active
material, and X-ray radiation. This article reports on the technical
work and scientific achievements that aimed at developing a new
inorganic scintillation filament to be used for the 3D printing of
composite scintillator materials: study and definition of the
scintillator composition; development of the methods for the
inorganic scintillator filament production and further
implementation in the available 3D printing technologies; study of
the impact of the different 3D printing modes on the material
scintillation characteristics. Also, 3D-printed scintillators can be
used to produce combined detectors for high-energy physics.
