Additive manufacturing enables radiation-functional polymer components with complex geometry, but performance depends on the interaction between active species, polymer optics, filler distribution, cure and geometry. Plastic scintillators require efficient energy transfer and photon collection; photon shields depend on composition, density, thickness and energy spectrum; neutron absorbers require isotope-specific interaction physics and secondary-radiation assessment; dosimetric and radiological phantoms require calibrated response or attenuation; and radiation-hard parts require retained properties after dose. This review organises these functions into separate qualification pathways. It emphasises optical attenuation and self-absorption in printed scintillators, energy-dependent shielding metrics, neutron-specific testing, dose-response calibration and radiation ageing. 3Dresyn PSci PPO and the 3Dresyns neutron-absorption additive family are presented only as commercial implementation examples, with no proprietary recipe or unsupported attenuation values disclosed.
