The Star Trek food replicator it’s not. But researchers at Columbia University in New York have created a 3D printer that makes cheesecake.
Mechanical engineers in the Creative Machines Lab at Columbia University have been experimenting with 3D-printed food (“food printers”) and laser cooking of food since 2005. The Department of Defense has been working to develop 3D-printed MREs (Meals Ready-to Eat) that in the future could be paired with wearable sensors to meet soldiers’ nutritional needs that day. NASA has also been experimenting with 3D-printed food for astronauts on long missions.
Until now, most 3D-printed foods have been made with uncooked ingredients, the researchers say. But in research published Tuesday in the journal npj Science of Food, the engineers describe how their 3D printer made a cheesecake from seven ingredients: graham cracker, peanut butter, Nutella, banana puree, strawberry jam, cherry drizzle, and frosting.

A retrofitted, off-the-shelf 3D-printer was used; the printing head could pick up any of the seven food “inks” to add to the slice. A blue laser was used to brown and crust the top surface of the graham cracker paste, Jonathan Blutinger, the lead author of the study and a postdoctoral fellow in the lab, told USA TODAY.
