Characteristics of Plastic Scintillators Fabricated by DLP 3D Printer

The 3D printer whose method is Digital Light Processing (DLP) was used to make plastic scintillators in an innovatively short time (20 minutes to 2 hours). Three kinds of acrylic monomers were used in the fabrication to see the effect on the detector performance depending on the monomer material. In this study, three types of tests were carried out. The light output relative to that of BC408 commercial plastic scintillator was estimated and compared. The highest light output was 45.2% for Sample 11. As a next task, we will investigate the performance of scintillators based on non-acrylic monomers fabricated by 3D printer.
