The primary objective of the present study was the development and validation of a three-dimensional (3D) anatomical
model of a pediatric hand (phantom) using 3D printing technology. The initial stage involved 3D printing of the mimicked
bone structures using ABS (Acrylonitrile Butadiene Styrene) filament, followed by the fabrication of a silicone mold, which
was then filled with a transparent polymer to simulate soft tissues. The phantom was validated through radiographic imaging
and computed tomography (CT). Radiographic images revealed a strong correlation between the anatomical structures of the phantom and those of a human hand, demonstrating the accuracy of the bone features. Based on CT analysis, the density values in Hounsfield Units (HU) for cortical bone (734.4 ± 75.2 HU) and trabecular bone (235.5 ± 43.9 HU) showed agreement with clinical data and relevant literature, confirming the reliability of additive manufacturing in replicating the radiological properties of bone tissue. However, the soft tissue covering (-160.4 ± 21.7 HU) suggested a predominantly adipose and aerated composition of the material used, indicating a potential area for future refinement to improve the representation of soft tissues. The developed phantom represents a cost reduction of over 95% compared to commercial models, without compromising the quality of bone tissue representation, further validating its application in both clinical practice and research contexts.
