Dosimetric characterization of 3D printed for 137Cs gamma rays

The aim this paper is characterize materials for 3D printed with different infill percentages for 137 Cs gamma rays. The RAISE 3D PRO2 printer was used to print PLA and ABS plates. Using a 137 Cs source, the attenuation coefficient was obtained by the transmission method and results compared with PMMA. The readings were performed by a Radcal ionization chamber, model 10X6-6. The results of attenuation coefficients show that the PLA filament demonstrated a equivalent behavior to PMMA. The PLA plates exhibits an increase in radiation transmission when reduces the infilling, and ABS printing achieved same results for all infills.
