Abstract
PurposeThe aim of this study was to determine the efficacy of using 3D printing models in the learning process of orbital anatomy and pathology by ophthalmology residents.MethodsA quasi-experimental study was performed with 24 residents of ophthalmology at Mashhad University of Medical Sciences. Each stratum was randomized into two groups. The educational booklets were distributed, and various forms of orbital 3D models were printed from orbital computed tomography (CT) scans. Knowledge enhancement on the topics was measured by comparing pretest and posttest scores.Results Thirteen residents who were trained using traditional methods were deemed the control group; while 11 residents who were trained using the 3D printed models were classed as the intervention group. The control group was younger than the intervention group (P = 0.047). The results showed that there was a statistically significant difference in the total posttest scores between the two groups. Based on the repeated measures of the analysis of variance (ANOVA), score variables were significant between the two groups (P = 0.008). Interestingly, the use of the 3D educational model was more effective and statistically significant with the year one residents as compared to the year two residents (P = 0.002).ConclusionThis study is the first one in Iran quantifying the effects of learning using 3D printed models in medical education. In fact, 3D modeling training is seemingly effective in teaching ophthalmic residents. As residents have never encountered such technology before, their experience using 3D models proved to be satisfactory and had a surprising positive effect on the learning process through visual training.

Summary
In the era of communication, innovative changes in the science and technology industry have facilitated greater access to valuable information. The advent of 3D printing has created new ways to complement the health practice. These exciting new technologies allow for the uniqueness and customized visualization in the production of various imaging process of medical tools and assist in devising complex and customized objects.[2]. When used for specific medical purposes, 3D printing technology is recognized as one of the newest devices in expanding the use of health-related innovations.[2]. The results showed that as a result of the use of the 3D models in training, the pediatric cardiopulmonary residents were motivated to acquire more information about congenital heart disease.[3].
