The precise delivery of radiation dose to tumors while sparing healthy tissues is a cornerstone of effective radiotherapy, demanding rigorous pre-treatment validation. Dosimetric phantoms are essential tools for this validation, yet conventional designs often lack anatomical realism. This study addresses the need for more patient-specific and accessible quality assurance tools by developing and evaluating a 3D-printed head phantom. It was hypothesized that a universal head phantom fabricated via fused filament fabrication from polylactic acid could provide dosimetric accuracy comparable to clinical standards. The phantom was designed, printed, and then underwent a full cycle of radiation therapy: CT simulation, planning of radiation therapy with intensity modulation (IMRT) and arc modulation (VMAT), irradiation with photon beams of 6 and 10 MeV. Dose was measured using a farmer-type ionization chamber and radiochromic films. The results showed excellent agreement between measured and planned doses, with deviations of less than 1% for point measurements and a gamma analysis passing rate exceeding 95% (3%/3 mm criteria) for 2D dose distributions. These findings confirm that the developed 3D-printed phantom is a reliable and versatile tool, demonstrating significant potential for enhancing quality assurance procedures in clinical radiotherapy and for facilitating controlled dosimetric research
