Özet:Title screen
This study demonstrates that 3D-printed PLA plastic samples significantly alter the proton beam’s Bragg peak, with degradation strongly dependent on printing parameters and beam energy. Internal heterogeneity from infill patterns and fill factor drives this effect. Lower fill percentages create alternating material-air regions, causing multi-peaked, step-like depth-dose distributions instead of a sharp peak. Quantitative analysis shows Bragg peak degradation begins at 80% fill for Rectilinear and 90% for Gyroid patterns, setting critical thresholds for dosimetric accuracy. Beam energy affects degradation: lower energies (70 MeV) show peak splitting, while higher energies (150 MeV) cause peak broadening. Precise control of 3D printing parameters, especially high fill factors, is essential for proton dosimetric phantoms, as manufacturing-induced heterogeneities that affect the dose accuracy
