Resumo
The aim of this paper is to characterize 3D printed phantoms and printing set-ups with different infill percentages
for imaging energy X-ray beams attenuation. 3D printing performance was studied using the fused filament
fabrication (FFF) technique with PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) filaments.
Phantom plates were printed and, using the Pantak Seifert X-ray system with different beam qualities in the
diagnostic range, the attenuation coefficients were obtained experimentally with the transmission method and
results compared with PMMA used as reference and theoretical data. Different percentages of infill of printed
phantoms were also evaluated and transmission characterized. The attenuation coefficients were determined for
the different beam qualities and results show that the variation in the values of attenuation coefficients decreases
as the infill quality increases. Attenuation characteristics evaluated indicates the suitable equivalence of PLA to
PMMA for 3D printing water/tissue equivalent most complex geometry phantoms. The different printing modes
characterized together with their attenuation coefficients for the X-ray beams will be studied and used in the
development of new 3D printed phantoms in our institute.
