=== Three-dimensional printing of food ===
Three-dimensional (3D) printing, also known as additive manufacturing, is the process of using digital files to create three dimensional objects. In the food industry, 3D printing of food is used for the processing of food layers using computer equipment. The process of 3D printing is slow, but is improving over time with the goal of reducing costs and processing times. Some of the successful food items that have been printed through 3D technology are: chocolate, cheese, cake frosting, turkey, pizza, celery, among others. This technology is continuously improving, and has the potential of providing cost-effective, energy efficient food that meets nutritional stability, safety and variety.<ref name=":32">{{Cite book|last1=Murlidhar|first1=Meghwal|last2=Goyal|first2=Megh Raj|url=https://www.worldcat.org/oclc/955601763|title=Food Engineering: Emerging Issues, Modeling and Applications|date=18 November 2016 |isbn=978-1-77188-369-6|location=Oakville, ON, Canada|oclc=955601763}}</ref>
