Background: Learning anatomy and promoting practical skill and abilities constitute an important part of medical curriculum. 3D printer models are regarded as a suitable substitute in terms the variety, handling, low weight and cost compared to other models. The most important goals of this project included producing a correct and successful of scanning, receiving the processed output and the 3D printing of the high quality educational models with lower cost.
Materials and Methods: Two anatomical models of larynx and pancreas and two fetal models were 3D scanned. Using 3D software, the scanned pictures were processed base on the type, density percentage, size, number of outer layers and the supporting structure. The output files with layered melting PLA filament 3D printing in sizes of 100%, 75% and 50%
Results: The details of 3D print models of the larynx and pancreas, including the cartilages, muscles, ducts, vessels and nerves were similar to the original models. The features of embryo models, included pharyngeal arches and clefts, somites, visual and auditory vesicles, cardiac swelling, and limb bud are similar to original models. The weight of 3D models was found to be one-third to one-tenth also the cost of 3D printing is 1% to 3% of the original models.
Conclusion: 3D printing models have better quality and low cost in comparison of original models. The 3D scanning, processing and printing technology allows the provision of quality practical classes. Students can enjoy a promoted learning due to the advantage of having access to 3D printed samples outside of the classroom, also.
