The use of 3D printing in the food industry is relatively new, most of the little 3D printing equipment developed for the food industry are still in the elementary design concept. topic deals with the concept of 3D printing, types of 3d food printing, benefits of 3d food printing, challenges to overcome while printing, a brief overview of what the research has reached till now.
