Resumo
The aim of this study was to evaluate the feasibility of using acrylonitrile butadiene styrene (ABS) and polylactic
acid (PLA) 3D printing filaments as materials for mammography phantom construction, comparing their
attenuation properties at two different set-ups: at a Calibration Laboratory and directly to a mammography
unit. The attenuation of 3D printed test phantoms of two types of common 3D printing Fused Filament
Fabrication (FFF) filaments (ABS and PLA) were characterized in comparison with polymethylmethacrylate
(PMMA). The measurements were carried out with standard IEC 61267 X-rays, using RQR 2-M and RQR 4-M
beam qualities at the Instruments Calibration Laboratory, and then applied to a mammography unit, with
measurements with 28 kV and 35 kV. Attenuation characteristics evaluated indicate the suitable equivalence of
PLA to PMMA for 3D printing breast complex phantoms. The plastic materials used in this study suggest that
the FFF technique may be suitable for mammography phantom development.
