Using a 3D food printer as a teaching tool: Focus groups with dietitians,teachers, and nutrition students

Three‐dimensional (3D) food printing is a new technology that can be used to produce personalized and customized food products. However, very little research has been completed on how 3D food printers could be used as educational tools. As such, the objective of this study was to evaluate how teachers (n = 6), dietitians (n = 6), and nutrition students (n = 11) envision the use of 3D food printers when disseminating information about food and nutrition. Focus groups were conducted with teachers, dietitians, and nutrition students. Initially, the participants were introduced to the concept of 3D food printing and then they were asked how they could use a 3D food printer in their teachings. The participants did not feel that a 3D food printer would enhance their teaching and instead felt it could confuse or frighten people. Also, all of the participants were worried about learning how to 3D print foods. The participants did state that people would be interested in watching a 3D food printer. Furthermore, the teachers and nutrition students indicated they thought a demonstration of a 3D food printer would lead to more interest in food and nutrition. Additionally, they thought a 3D food printer could be used to create visually appealing foods. Overall, until 3D food printers are found in residential and commercial kitchens, the participants did not think it would enhance their teachings; however, they did indicate that 3D food printing demonstrations could lead to students being interested in the food and nutrition fields.

Production of accurate skeletal models of domestic animals using three‐dimensional scanning and printing technology

Access to adequate anatomical specimens can be an important aspect in learning the anatomy of domestic animals. In this study, the authors utilized a structured light scanner and fused deposition modeling (FDM) printer to produce highly accurate animal skeletal models. First, various components of the bovine skeleton, including the femur, the fifth rib, and the sixth cervical (C6) vertebra were used to produce digital models. These were then used to produce 1:1 scale physical models with the FDM printer. The anatomical features of the digital models and three‐dimensional (3D) printed models were then compared with those of the original skeletal specimens. The results of this study demonstrated that both digital and physical scale models of animal skeletal components could be rapidly produced using 3D printing technology. In terms of accuracy between models and original specimens, the standard deviations of the femur and the fifth rib measurements were 0.0351 and 0.0572, respectively. All of the features except the nutrient foramina on the original bone specimens could be identified in the digital and 3D printed models. Moreover, the 3D printed models could serve as a viable alternative to original bone specimens when used in anatomy education, as determined from student surveys. This study demonstrated an important example of reproducing bone models to be used in anatomy education and veterinary clinical training.
