Purpose/Background: Technological progress consistently shapes and improves patient care and education. The role of 3D printing has become increasingly prominent in the medical sphere, providing anatomical models of unparalleled accuracy. These models are integral in enhancing surgical education and training for residents.

Methods/Interventions: Using advanced 3D printing methods, we developed a multi-colored pelvic model. Preoperative imaging from a rectal cancer patient informed the design, with the Immersive Touch workflow detailing the anatomy. This design was printed on Formlabs devices, using distinct acrylic shades for anatomical clarity. The employed printing techniques achieved a realistic anatomical texture. For cost-efficiency, the model was scaled to half its original size, and a biocompatible, sterilizable resin was used, ensuring medical suitability.

Results/Outcomes: We introduced two intricately designed models, each partitioned to enable straightforward assembly and detailed analysis. The first model presents a coronal sectioning posterior to the pelvic cavity and incorporates a detachable spinal segment, allowing for a clear posterior view of the anatomical layers. In contrast, the second model, delineated by a sagittal division along the pelvic cavity's midline, offers an expansive view of the colorectal anatomy. A distinctively colored region within this model indicates the tumor's position.

Conclusion/Discussion: Our prototype model not only stands as a testament to the capabilities of 3D printing in medical education but also offers a tangible, realistic, and safe tool for surgical training. The distinct coloring, combined with the model's meticulous design, ensures that it can significantly benefit surgical residents in understanding intricate anatomical relations and tumor positioning. Future endeavors in this direction can further push the boundaries of hands-on surgical education.
