they can also be 3D printed for demonstrative purposes in legal proceedings and training, without risk of damage to the original skeletal material. As its application in forensic anthropology is relatively novel, the aim of the present study is to statistically evaluate the dimensional accuracy of 3D structured light scans and 3D prints for ten bone types, including the cranium, mandible, 2nd cervical vertebra (C2), clavicle, scapula, capitate, 2nd metacarpal, os coxae, femoral head, and patella. Standard linear measurements are acquired in each physical bone, 3D virtual model, and 3D print of the same bone specimen. Variances between measurements of physical, virtual, and printed bones are quantified using the technical error of measurement (TEM), relative TEM (rTEM), and coefficient of reliability (R). Measurements acquired in the virtual models and prints were found to be within ±2 mm average of the same measurements in the physical bones, with a tendency to underestimate true value. rTEM and R values for the virtual clavicle, capitate, scapula and C2, and rTEM for the printed clavicle and capitate, were comparatively less reliable than for other bone types; although all bones were reproduced to within acceptable anthropological error standards (rTEM≤5 %; R≥0.95). This study reaffirms the use of 3D structured light scanning and 3D printing to complement traditional skeletal documentation in forensic anthropology.</p></div></div> <div class="rendering rendering_researchoutput rendering_researchoutput_detailsportal rendering_contributiontojournal rendering_detailsportal rendering_contributiontojournal_detailsportal"><div class="article"><table class="properties"><tbody><tr class="language"><th scope="row">Original language</th><td>English</td></tr><tr><th scope="row">Article number</th><td>112138</td></tr><tr class="numberofpages"><th scope="row">Number of pages</th><td>8</td></tr><tr><th scope="row">Journal</th><td><a rel="Journal" href="#" class="link"><span>Forensic Science International</span></a></td></tr><tr><th scope="row">Volume</th><td>361</td></tr><tr><th scope="row">Early online date</th><td><span class="date">13 Jul 2024</span></td></tr><tr class="digital_object_identifiers"><th scope="row">DOIs</th><td><ul class="relations digital_object_identifiers"><li><a onclick="window.open(this.href, '_blank','noopener,noreferrer'); return false;" href="https://doi.org/10.1016/j.forsciint.2024.112138" class="link"><span>https://doi.org/10.1016/j.forsciint.2024.112138</span></a> </li></ul></td></tr><tr class="status"><th scope="row">Publication status</th><td><span class="prefix">Published - </span><span class="date">Aug 2024</span></td></tr></tbody></table></div></div> </div> <div class="content-sidebar publication-sidebar"> <div class="sdg-content-wrap publication"> <h2 class="subheader">UN SDGs</h2> <p class="sdg-text">This output contributes to the following UN <a href="https://www.un.org/sustainabledevelopment/sustainable-development-goals/" target="_blank">Sustainable Development Goals (SDGs)</a></p> <ul class="sdgs-content"> <li> <img alt="SDG 3 - Good Health and Well-being" title="SDG 3 - Good Health and Well-being" class="good_health_and_well_being" src="/assets/sdg_icons/good_health_and_well_being-ca66cb937719976ce918816020def2ec.svg"/> </li> </ul> </div> <h2 class="subheader">Access to Document</h2> <div class="rendering rendering_researchoutput rendering_researchoutput_publicationaccessrenderer rendering_contributiontojournal rendering_publicationaccessrenderer rendering_contributiontojournal_publicationaccessrenderer"><ul class="dois"><li class="open-access"><div class="doi"><a onclick="window.open(this.href, '_blank','noopener,noreferrer'); return false;" href="https://doi.org/10.1016/j.forsciint.2024.112138" class="link"><span>10.1016/j.forsciint.2024.112138</span></a><span class="meta">Licence: <a onclick="window.open(this.href, '_blank','noopener,noreferrer'); return false;" href="http://creativecommons.org/licenses/by/4.0/" class="link">CC BY</a></span></div></li></ul></div> <h2 class="subheader">Other files and links</h2> <div class="rendering rendering_researchoutput rendering_researchoutput_publicationotherfilesandlinksrenderer rendering_contributiontojournal rendering_publicationotherfilesandlinksrenderer rendering_contributiontojournal_publicationotherfilesandlinksrenderer"><ul class="links"><li><div class="link"><a onclick="window.open(this.href, '_blank','noopener,noreferrer'); return false;" href="http://www.scopus.com/inward/record.url?scp=85198275557&partnerID=8YFLogxK" class="link"><span>Link to publication in Scopus</span></a></div></li></ul></div> </div> </div> </div> </section> <section class="page-section content-relation-section publication-fingerprint"> <div class="container"> <div class="header"> <h2 class="section-title"> <i class="icon icon-fingerprint" aria-hidden="true"></i> <span class="title">Fingerprint</span> </h2> <span class="sub-title"> Dive into the research topics of 'Dimensional accuracy of structured light scans and 3D prints of various human skeletal elements'.
