In stabbing related fatalities, the forensic pathologist has to assess the direction of wound track (thus, the direction of the stabbing) and the weapon’s possible characteristics by examining the stab wound. The determination of these characteristics can be made only with a high level of uncertainty, and the precise direction of the stabbing is often difficult to assess if only soft tissues are injured. Previously reported techniques used for the assessment of these wound characteristics have substantial limitations. This manuscript presents a method using today’s easily accessible three-dimensional (3D) printing technology for blade-wound comparison and wound track determination. Scanning and 3D printing of knives is a useful method to identify weapons and determine the precise stabbing direction in a stabbing incident without compromising the trace evidence or the autopsy results. Ballistic gel experiment, and dynamic stabbing test experiments prove the method can be applied in safety, without compromising the autopsy results. Identification of the exact knife is not possible with complete certainty but excluding certain knives will decrease the number of necessary DNA examinations, hence it can lower the burden on forensic genetic laboratories. The method addresses many of the shortcomings of previously used methods of probe insertion or post-mortem CT. Insertion of the printed knife into the wound gives a good visual demonstration of the stabbing direction, thus easing the forensic reconstruction of the stabbing incident. After combining the 3D printing with photogrammetry, the achieved 3D visualization is useful for courtroom demonstration and educational purposes.

“…Three-dimensional surface scanning (3DSS) has the ability to collect data from various directions/angles without physically handling [ 41 ]. Previous work has demonstrated that this approach to recording and analysing human remains is superior to 2D and photogrammetric methods [ 9 , [42] , [43] , [44] , [45] , [46] , [47] ].…”

“…examination of fragile and otherwise inaccessible material, the production of affordable, high-quality replicas for display, teaching, and research, increased accuracy and enhanced data sharing [ [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , 17 , 18 ]. The use of surface scanning in forensic anthropology and medicine has been well established [ 19 ], in contexts such as the analysis of burned remains [ 20 ], replication of anthropological specimens for curation and illustration [ 20 ], recording taphonomic changes [ 21 ], evaluating trauma [ 1 , 22 ], determining bullet pathways [ 23 ], and presenting evidence in court [ [24] , [25] , [26] ].…”

The preservation and reconstruction of anthropological and archaeological remains has been given considerable attention in recent years, particularly within the fields of forensic science and palaeoanthropology. However, few studies have tapped the potential of using 3D technology to reconstruct, remodel and recontour remains and artefacts for the purpose of human identification. The aim of this study was to use 3D technology for the reconstruction and remodelling of fragmented and missing elements of skeletal remains. This project presents the application of three dimensional (3D) modalities to two different simulated forensic case scenarios where an attempt was made to remodel the missing element of the human cranium and reconstruction of fragmented replicated human mandible was performed. The accuracy of the reconstructed model was affirmed based on the anatomical features and digital analysis and methods for use in forensic practice are recommended.
