Scientists Make a Seven-Ingredient 3D-Printed Cheesecake
The researchers 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.

Columbia University scientists three-dimensionally (3D)-printed a slice of seven-ingredient peanut butter-banana cheesecake with a cherry drizzle.
The researchers converted the ingredients into a paste, then fed it into the 3D printer for layered deposition into the shape of the cake slice.
They found the print's structure was similar to that of a house, with "floors, walls, and ceilings being the foundation (graham cracker) and inner pools (Nutella and peanut butter) holding softer ingredients within (banana and jelly)."
The researchers suggested 3D printing food could enable cooks to better customize meals and prevent the spread of food-borne illnesses by reducing human contact.
