  Plastic scintillator detectors are widely used in particle physics thanks to
the very good particle identification, tracking capabilities and time
resolution. However, new experimental challenges and the need for enhanced
performance require the construction of detector geometries that are
complicated using the current production techniques. In this article we propose
a new production technique based on additive manufacturing that aims to 3D
print polystyrene-based scintillator. The production process and the results of
the scintillation light output measurement of the 3D-printed scintillator are
reported.
