Replicating Livers Through 3D Printing for Surgical Training

a Cost-Effective Approach

Abstract

This research paper explores a unique approach to medical training and surgical planning using 3D-printed gelatin molds to replicate the liver's anatomy. Traditional methods, such as the use of synthetic materials or cadavers, often fall short. Gelatin presents a promising alternative. In this study, we used Tinkercad, a user-friendly 3D modeling software, to design and render a precise liver model previously rendered in thingiverse. To ensure the models were as realistic as possible, we measured hardness, puncture resistance, and elasticity. These scales helped determine how closely the gelatin models replicated the physical characteristics of an actual liver. We determined if these gelatin molds can serve as realistic and cost-effective tools to improve pre-surgical planning with detailed anatomical models.  Our 3D-printed gelatin molds will enhance medical education by offering a more hands-on learning experience, improve surgical precision through better preoperative planning, and advance research by simulating liver properties, because the results show that they can in fact mimic a real pig liver, specifically the 12 gram mold liver showing the most similarities. We hope that our findings will significantly contribute to the fields of medicine and biomedical research, offering a practical and innovative solution to current limitations.
