3D food structure and science behind the inherent chemical interactions and binding of the deposited layers have not yet been clarified. Researchers all around the world were working in exploring the potential applications of food printing for mass customization, personalized nutrition, intricate designing, etc. In terms of cost, food printing remains to be cheaper than conventional food processing techniques as printing combines multiple steps and eliminates human interventions. 3D food printing allows fabrication of edible 3D constructs of complex designs and helps in food customization. With the technological advancements, food printing seems to be a futuristic technology that would turn the so‐called ‘balanced diet’ into a ‘digitalized diet’.
