The application and challenges of 3D printing technology in food

Abstract

This paper reviews the principle, development history and current situation of 3D food printing technology, focusing on the application of 3D printing technology in food, as well as some problems and challenges it faces. The main research methods adopted are literature review and questionnaire survey. After investigation, the application field of 3D food printing technology is very considerable, but at the same time, many problems in different aspects also hinder its popularization. As long as the obstacles are solved, 3D food printing technology is expected to become the main technology in food production in the future, and then move towards 4D technology.
