Analyzing 3D food printing research trends, future directions, and feasibility in Bangladesh

Using additive manufacturing technology, 3D food printing is a contemporary technique that creates food products layer by layer using edible materials and digital graphics. Personalized nutrition and innovative food design have driven the technique's popularity, along with efforts to enhance the nutritional content of foods. We have examined the current research shift and anticipated future research on 3D food printing in this descriptive study. A comprehensive bibliometric analysis of the topic “3D food printing” was conducted in the Scopus dataset from 2015 to 2024 to capture current research trends. To provide readers with a summary of the current research trend, the most popular terms have been examined. The top burst keywords, on the other hand, have been carefully examined in light of recent frequency in order to identify research hotspots and predict future directions. Both topic modeling and research evolution forecast on the modelled topics are accomplished by deep learning analyses, namely SciBERT, HDBSCAN, UMAP, and Prophet. Bangladesh faces a severe food and nutrition crisis because of poor land quality, insufficient water resources, and weak agricultural support, which impacts half of the children under five years old. Safety risks and concerns regarding 3D-printed foods and the introduction of 3D food printing technology in Bangladesh, as reported in previous literature, are discussed at the end of this study. This descriptive study should result in a deeper understanding of the available and emerging areas of research concerning 3D printing for food, as well as the distribution strategy of 3D food printing technology in Bangladesh.
