Resumo
With the popularization of 3D printing technologies, it is now possible to develop
patient specific simulators and various other accessories using this technology in medical
physics and dosimetry. This work aims to evaluate the electronic equilibrium of 3D printed
phantoms using PLA and ABS filaments compared to PMMA for 137Cs gamma rays using OSL
dosimetry. A Landauer microStar ii commercial OSL system was commissioned and it was
used nanoDot dosimeters. Phantom plates with 2.5, 3.0 and 5.0 mm thickness were used to
obtain electronic equilibrium for 137Cs gamma rays. Measurements were compared with
PMMA measurements at standard conditions. Results show that measurements with ABS and
PLA thicknesses of 2.5 and 3.0 mm presents dosimetry results within irradiation uncertainty.
More accuracy is obtained using 3.0 mm for both PLA and ABS phantoms, with differences in
less than 0.5%. It can be concluded that PLA and ABS 3D phantom plates has similar
properties of PMMA for 137Cs gamma rays dosimetry and can be used for developing
dosimetry accessories for this energy photon beam.
