This study presents a rapid and cost-effective methodology for manufacturing glandular breast models intended for health education purposes. The main objective was to assess a hybrid fabrication approach that combines additive manufacturing with vacuum polymer casting in terms of its capability to reproduce the complex internal architecture of heterogeneously dense breast tissue for medical training applications. The proposed method enables realistic representation of glandular tissue, adipose tissue, and cancerous lesions. The external geometry of the model was acquired using 3D scanning of the human torso, whereas the internal anatomical structures and pathological changes were reconstructed through segmentation of medical imaging data. Subsequent stages included the fabrication of 3D-printed molds and the selection of silicone materials suitable for reproducing the anatomical characteristics of breast tissue. The final product was manufactured using a complex assembly process. This involved the use of castings produced in separate molds, the order of which is crucial in terms of the stability and accuracy of the process. The components possess different mechanical properties, which better reflects the glandular breast anatomy. Qualitative evaluation demonstrated that the developed approach successfully replicates heterogeneously dense breast tissue, accurately reflecting the spatial distribution of glandular and adipose components. The proposed methodology therefore constitutes an accessible and anatomically realistic alternative to commercially available training phantoms, offering valuable support for patient education and breast self-examination training.
