Establishing a Resident-Driven Three-Dimensional Printing Lab Within an Academic Institution

Abstract

Background: Three-dimensional (3D) modeling and printing technologies have been increasingly used throughout healthcare for research, educational, and clinical purposes. Despite the benefits associated with their use in surgical training, the literature poorly outlines the value of establishing an in-house, resident-driven 3D printing lab. Herein, we outline our quantifiable experience with our 3D printing lab and outline all necessary components needed to establish a lab such that the reader can replicate our experience at their institution. Additionally, we outline the process of creating a 3D-printed model from patient imaging with supplementary tutorial videos. Methods: A retrospective review of all 3D-printed models created in our in-house 3D printing lab since its creation in 2022 was performed. 3D-printed models that were utilized for formal educational or clinical purposes were included in this study. All 3D-printed models were created using the Raise3D 2 Pro. Cost estimates associated with each print were collected from the printer’s cost estimation function. Results: A total of 14 3D-printed models met the inclusion criteria for our study. Of these, 4 (28.6%) were utilized for patient and/or resident education with the remaining 10 (71.4%) being used in patient care. By and large, the average cost of educational 3D-printed models was greater than clinical models ($12.00 vs $1.50, respectively). Ten 3D-printed models of mandibular fractures were successfully used to pre-bend plates prior to reconstructive surgery, and minimal intraoperative adjustment of the plate was required for each case. The processes of establishing a 3D printing lab along with creating a 3D-printed model from patient imaging are outlined. Conclusion: Establishing a 3D printing lab is an attainable feat for most institutions. High-value clinical and educational tools can be created for a reasonable price once the initial overhead costs of establishing a lab are covered.
