In this study, we report the fabrication and characterization of a 3D printed polyvinyl toluene based plastic scintillator by DLP (digital layer print) 3D printer. The homemade resin has been used for 3D printing. The organic solvents such as vinyl-toluene monomer, PPO (2,5-Diphenyloxazole), POPOP [1,4-bis(5-phenyloxazol-2-yl) benzene], pentaerythritol tetrakis (3-mercaptopropionate), and DHPA (dipentaerythritol hexa-acrylate) have been used as co-polymers. Irgacure 184 (BASF Co.) is used as photo-initiator. Using DLP 3D printer (http://attosystem.co.kr) and the prepared resin, a plastic scintillator is printed. The emission spectrum of the printed plastic scintillator is located between 400 and 600 nm, peaking at 424 nm. The relative light yield of the scintillator is about 80% of EJ-200, relatively, and the decay time is about 3.9 ns.
