“…6 Thermoplastic filaments used for FDM printing also vary tremendously in material composition, porosity, and environmental stability. 7 Many FDM filaments retain ambient moisture, which could pose a paradoxically increased risk for virus transmission during use or reuse. 8 In addition, the combination with filter media such as high efficiency particulate air (HEPA) filtration systems has not currently been endorsed as a means of increasing the safety profile of 3D-printed PPE prototypes.…”

The recent decline in available personal protective equipment (PPE) due to the novel coronavirus (COVID-19) pandemic has given rise to a host of three-dimensional (3D) printed prototypes for facemask and respirator units. Many of these models have been made open access and publicly available for printing and use, and have been promoted by various media outlets. Although these desktop 3D printing measures have provided a possible venue for success in providing homemade and cost-effective PPE to health care workers, the rapid dissemination of these prototypes has been performed without reproducible methods of standardization and vetted safety in use. Although these methods have not been sanctioned by authoritative organizations as viable production approaches to address the PPE shortage, a concerted effort within the 3D printing community to adhere to scientific methodology and organized research efforts has the potential to provide a solution to this critical issue.

“…This portion of the experiment confirmed the prediction of the virtual simulation, and each T12 pedicle could be successfully cannulated by following the proposed steps. This was accomplished due to the established accuracy of 3D printing in preserving important anatomical landmarks and surface anatomy (Katkar, Taft, & Grant, ).…”

Ex vivo virtual and 3D printing methods for evaluating an anatomy‐based spinal instrumentation technique for the 12th thoracic vertebra

Introduction Three‐dimensional printing and virtual simulation both provide useful methods of patient‐specific anatomical modeling for assessing and validating surgical techniques. A combination of these two methods for evaluating the feasibility of spinal instrumentation techniques based on anatomical landmarks has not previously been investigated. Materials and Methods Nineteen anonymized CT scans of the thoracic spine in adult patients were acquired. Maximum pedicle width and height were recorded, and statistical analysis demonstrated normal distributions. The images were converted into standard tessellation language (STL) files, and the T12 vertebrae were anatomically segmented. The intersection of two diagonal lines drawn from the lateral and medial borders of the T12 transverse process (TP) to the lateral border of the pars and inferolateral portion of the TP was identified on both sides of each segmented vertebra. A virtual screw was created and insertion into the pedicle on each side was simulated using the proposed landmarks. The vertebral STL files were then 3D‐printed, and 38 pedicles were instrumented according to the individual posterior landmarks used in the virtual investigation. Results There were no pedicle breaches using the proposed anatomical landmarks for insertion of T12 pedicle screws in the virtual simulation component. The technique was further validated by additive manufacturing of individual T12 vertebrae and demonstrated no breaches or model failures during live instrumentation using the proposed landmarks. Conclusions Ex vivo modeling through virtual simulation and 3D printing provides a powerful and cost‐effective means of replicating vital anatomical structures for investigation of complex surgical techniques.

“…For example, overlaying the rendered virtual 3D model of a patient's aortic root with preformed virtual 3D models of implantable aortic valves allows for precise preprocedural sizing and positioning of the implant, and is routinely performed in planning of transcatheter aortic valve implantation procedures (TAVI) [34]. However, the presentation of virtual 3D reconstructions on 2D displays is sometimes regarded as a limiting factor, especially for persons used to haptic feedback, i.e., surgeons [22]. Augmented reality and virtual reality are emerging promising technologies to further the potentials of 3D imaging; however, these are outside of the scope of this article [37].…”
