3D printed reconstructions of skeletal material offer a novel, interactive and increasingly used tool to support
courtroom testimony and aid juror interpretation of expert testimony. While research has begun to address the
accuracy of 3D printed skeletal material, there has been little consideration of the diverse applications of prints to
support trauma demonstrations, particularly in relation to gunshot trauma. This study explored the suitability of
three printed human crania replicas exhibiting either gunshot trauma or blunt force trauma for identifying
whether the prints were sufficiently accurate for the presentation of trauma wounds. The data indicate that
metric measurement and qualitative assessment of trauma macromorphology was possible from the 3D printed
reconstructions. The findings also offer an indication that it is possible to obtain data around the accuracy of 3D
printing bullet wounds and for establishing a bullet path. However, some limitations of prints reconstructed from
post-mortem computed tomography (PMCT) data were identified including the observation that not all fracture
lines were successfully replicated which indicates that at present virtual models should be used concurrently with
3D prints in court
