The 3D printing technology can become a useful tool in applied education. This technology has great potential to provide a source of high quality teaching materials. The purpose of the study was the creation and evaluation of Anatomical Models of 3D Patellar Luxation (3DAMPL) as a didactic material on the Teaching of Applied Animal Anatomy. The development of 3DAMPL started from the need to represent the different degrees of severity of Patellar Luxation (PL) during practical classes. The creation was based on the 3D scanning of In natura bones corresponding to the femur, tibia, fibula and patella. The editing was done in software program (Autodesk Meshmixer©, version 3.1, Autodesk Inc.©, California, United States). The modeling and manufacture was performed on 3D printer (Pro – GTMax3D Core A3 ® , GTMax Tecnologia©, São Paulo, Brazil). Subsequently, 3DAMPL radiographs were performed on digital x‐ray equipment (General Electric DR‐F, General Electric Company©, United States) to illustrate the different degrees of disease in the different positions. We evaluated the potential of the 3DAMPL as a tool to increment the learning during practical classes. All the students signed the Term Free and Informed Consent (TCLE). A class composed of 36 students of the Veterinary Medicine course (Universidade Federal do Acre) was randomly distributed into two groups: Traditional (n = 18) and 3DAMPL (n = 18); submitted to the theoretical‐practical class and evaluated through questionnaires (Pre‐Test / Class / Post‐Test). The general analysis of the questionnaires showed that the mean number of correct answers between the two groups was similar at the Pre‐test (p= 0.148) and at the Post‐test (p= 0.529). A significant difference (p< 0.05) among Pre‐test and Post‐test was observed in Traditional and 3DAMPL groups. The replacement of traditional X‐ray images with 3DAMPL images did not interfere in the way that the students learned about the subject. After the class, there were no significant differences between the groups. Students can study the subject by looking at 3DAMPL images and then identify the disease in traditional X‐ray images. The models (3DAMPL) and their radiographs can be an educational alternative, supplying the lack of representative materials for the teaching of PL.
