The 3D Printed Cheesecake Revolution: Scientists Perfect the Recipe.

Researchers at Columbia University have used a 3D printer to create a seven-ingredient slice of cheesecake, suggesting that printing food could be a new cooking option with several benefits. The researchers defined printed food as "the controlled deposition of an ingredient," and say many existing processed foods can be considered "printed" by this definition. They also see sustainability benefits to printing food, because ingredients can be locally sourced, plant-based meals can be created and the shelf life of the foods could be extended.
