This study aimed to construct a tissue-equivalent anthropomorphic phantom using 3D printing to enable dosimetry with radiochromic films of the optical apparatus in external beam radiotherapy. Slices were developed based on and intended to be used in conjunction with the reference phantom ATOM. 3D printing with polylactic acid (PLA) was utilized to represent soft tissues, while a mixture of gypsum, salt, and water was used as a skull bone simulator. The validation of the phantom was conducted through Hounsfield Units (HU) assessments to verify the homogeneity and compatibility with the ATOM phantom. Homogeneity was confirmed with a variation of 28.1% in the PLA component and 6.6% in the gypsum mixture. The results also demonstrated compatibility with the materials of the ATOM phantom. The phantom was successfully constructed and validated, making it suitable for testing as a dosimetric system for evaluating doses in the ocular region during radiotherapeutic procedures.
