“…Imaging-based reconstruction of pathologies and subsequent AM of colored, subject-specific demonstrative replica have been proposed as effective methods for forensic medicine, 20 not only because they could help improve understanding of pathologies but also because they are excellent instruments to facilitate communication in court rooms.…”

Additive Manufacturing of Biomaterials, Tissues, and Organs

Abstract-The introduction of additive manufacturing (AM), often referred to as three-dimensional (3D) printing, has initiated what some believe to be a manufacturing revolution, and has expedited the development of the field of biofabrication. Moreover, recent advances in AM have facilitated further development of patient-specific healthcare solutions. Customization of many healthcare products and services, such as implants, drug delivery devices, medical instruments, prosthetics, and in vitro models, would have been extremely challenging-if not impossible-without AM technologies. The current special issue of the Annals of Biomedical Engineering presents the latest trends in application of AM techniques to healthcare-related areas of research. As a prelude to this special issue, we review here the most important areas of biomedical research and clinical practice that have benefited from recent developments in additive manufacturing techniques. This editorial, therefore, aims to sketch the research landscape within which the other contributions of the special issue can be better understood and positioned. In what follows, we briefly review the application of additive manufacturing techniques in studies addressing biomaterials, (re)generation of tissues and organs, disease models, drug delivery systems, implants, medical instruments, prosthetics, orthotics, and AM objects used for medical visualization and communication.

“…Rapid prototyping was quickly applied to anthropological contexts (Seidler 1997;Zollikofer et al 1998), originally using machinery-based milling to create replicas from CT data (Barker et al 1994). Stereolithography (SL) replaced milling and turning machines as a more suitable alternative in the 1980s, as it could replicate internal structures by a process which builds models layer by layer, through selective solidification of a liquid monomer (Barker et al 1994;Ebert et al 2011;Hull 1986;Mankovich et al 1990). In more recent years, developments in 3D printing technology such as fused deposition modelling (FDM) and selective laser sintering (SLS) have allowed more researchers to create accurate physical 3D models, in shorter time periods, and at low costs (approximately one-third or less of a SL model (Cohen et al 2009;Ebert et al 2011)).…”

“…These errors could be due to several factors, such as model shrinkage, smoothing procedures, and filling of holes in preparation of the 3D surface model prior to production, removal of support structures, and the laser settings and thickness (Barker et al 1994;Choi et al 2002;Ebert et al 2011). While the implications of these estimations of error may be difficult to visualise, qualitative assessment of replicas produced through stereolithography indicates that they may correspond to loss of thinner elements of bone, under-visualisation of foramina, and loss of details in complex areas (Barker et al 1994).…”

“…For instance, the British Museum recently displayed the Jericho skull along with two 3D printed replicas, generated from CT data, allowing visitors to see the original cranial form as well as the numerous facial reconstructions that have been created (Hirst 2017). Replicas can also be used in a professional setting, for instance, in the production of reconstructions of injuries in forensic cases, which would allow juries to better visualise certain scenarios (Ebert et al 2011). In addition, 3D digitisation and replicas may be extremely useful in preserving material that is being reburied (Hjalgrim et al 1995) or repatriated, although the ethical and practical implications of this process are largely unexplored at present Hirst et al 2018).…”

________________________________________________________________The use of 3D data in the analysis of skeletal and fossil materials has conveyed numerous advantages in many fields; however, as the availability and use of 3D scanning equipment are rapidly increasing, it is important for researchers to consider whether these methods are suitable for the proposed study. The issue of suitability has been largely overlooked in previous research; for instance, casts and reconstruction methods are frequently used to increase sample sizes, without sufficient assessment of the effect, this may have on the accuracy and reliability of results. Furthermore, the reliability of geometric morphometric methods and the implications of virtual curation have not received sufficient consideration. This paper discusses the suitability of 3D research with regard to the accuracy, reliability, and accessibility of methods and materials, as well as the effects of the current learning environment. Areas where future work will progress 3D research are proposed. ________________________________________________________________Résumé: L'utilisation de données 3D dans l'analyse de matériaux squelettiques et fossiles a fourni de nombreux avantages dans plusieurs domaines, mais comme la disponibilité et l'utilisation de l'équipement de balayage 3D connaissent une montée rapide, les chercheurs doivent se demander si ces méthodes conviennent à l'étude proposée. Le problème de la convenance a été largement ignoré dans les recherches précédentes. Pour cas, des méthodes de moulage et de reconstruction sont souvent utilisées pour augmenter la taille des échantillons sans d'abord évaluer avec précision l'effet de celles-ci sur l'exactitude et la fiabilité des résultats. Qui plus est, la fiabilité des méthodes morphométriques géométriques et les répercussions de la conservation virtuelle n'ont pas fait l'objet de suffisamment d'attention. Le présent article discute de la convenance des recherches 3D relativement à l'exactitude, la fiabilité et l'accessibilité des méthodes et matériaux, ainsi que des effets de l'environnement d'apprentissage actuel. Nous y proposons des domaines où les travaux futurs feront avancer la recherche 3D. ________________________________________________________________Resumen: El uso de datos tridimensionales en el análisis de material esqueléticos y fó siles ha proporcionado numerosas ventajas en muchos campos, sin embargo, dado que la disponibilidad y el uso de equipos de escaneo en 3D está aumentando rápidamente, es importante que los investigadores consideren si estos métodos son adecuados para el estudio propuesto.
