In this qualitative study, the effects of using a 3D print, demonstrating a blunt force skull fracture, in court were explored by thematic analysis of interviews with judges, prosecutors, defence counsels, and forensic pathologists with the aim of improving the expert testimony. Five semi-structured focus groups and eight one-to-one interviews with a total of 29 stakeholders were transcribed <jats:italic>ad verbatim<\/jats:italic> and analysed using thematic analysis. The study found that a highly accurate 3D print of a skull demonstrated autopsy findings in detail and provided a quick overview, but sense of touch was of little benefit as the 3D print had different material characteristics than the human skull. Virtual 3D models were expected to provide all the benefits of 3D prints, be less emotionally confronting, and be logistically feasible. Both 3D prints and virtual 3D models were expected to be less emotionally confronting than autopsy photos. Regardless of fidelity, an expert witness was necessary to translate technical language and explain autopsy findings, and low-fidelity models may be equally suited as demonstrative aids. The court infrequently challenged the expert witnesses\u2019 conclusions and, therefore, rarely had a need for viewing autopsy findings in detail, therefore rarely needing a 3D print.<\/jats:p>","DOI":"10.1007\/s00414-023-03054-6","type":"journal-article","created":{"date-parts":[[2023,7,1]],"date-time":"2023-07-01T00:01:54Z","timestamp":1688169714000},"page":"1865-1873","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["3D printed skulls in court\u2009\u2014\u2009a benefit to stakeholders?"],"prefix":"10.1007","volume":"137","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4331-6094","authenticated-orcid":false,"given":"Mikkel Jon","family":"Henningsen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0565-0566","authenticated-orcid":false,"given":"Lykke","family":"Thorlacius-Ussing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1447-965X","authenticated-orcid":false,"given":"Lotte Groth","family":"Jensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8669-8897","authenticated-orcid":false,"given":"Kasper","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7257-0772","authenticated-orcid":false,"given":"Christina","family":"Jacobsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6177-5780","authenticated-orcid":false,"given":"Stina","family":"Lou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9967-8131","authenticated-orcid":false,"given":"Chiara","family":"Villa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,7,1]]},"reference":[{"issue":"3","key":"3054_CR1","doi-asserted-by":"publisher","first-page":"200","DOI":"10.1007\/bf03167610","volume":"3","author":"NJ Mankovich","year":"1990","unstructured":"Mankovich NJ, Cheeseman AM, Stoker NG (1990) The display of three-dimensional anatomy with stereolithographic models.
