How To 3D Print Food and Cook It Perfectly Using Laser Beams

Scientists from Columbia University have developed a way to 3D print food and cook it using laser beams, claiming that it will come to replace microwaves in the near future.

“We call it digital food because we are looking at food in a new way.” said Jonathan Blutinger, PHD researcher at Columbia University. In the future, you may only have to download a medium rare steak to enjoy it tonight for dinner. Based on what these scientists are saying you would still gain all the nutritional benefits or more then you would from a natural steak.

Mr Blutinger explained: “The food has been slightly pulverised into a way that it can be distributed through a nozzle and we can move a gantry around and create complex geometries to create interesting shapes with the food.” Admittedly not the most appetizing impression, however, its important to remember that most of our meat is made that way anyways, including hotdogs and hamburger meat. Transitioning to a household 3D printer would only give you better control over content and creation.

What’s particularly impressive is their ability to exploit machine learning in order to customize food to your personal tastes and nutritional requirements. “The more you use the machine, the more it will Learn about your eating habits – what you do and don’t like and what times in the day you tend to eat.”

“Additionally, everybody has their own tastes and dietary restrictions, so when you introduce a data-driven health approach, you can achieve customised and nutrition-rich meals on a per-person basis

“Since the machine has knowledge of all the ingredients, it can combine them in unique ways and tailor them to all of your biometric and nutritional needs.”

They claim that 3d printing acknowledges a lot of holes in contemporary manufacturing “There are food products which cannot be made by injection moulds or machining because of geometric constraints inherent to traditional manufacturing methods”

Microwaves have become a staple of modern civilization. Their fast and convenient nature has come to reflect our busy lifestyle. What if we could eliminate some of the negative side effects of microwaving and still leave most of the speed in tact? Microwaves for example are notorious for their uneven heat distribution – sometimes leaving the outside too hot and the inside too cold. Researchers states that laser cooking could end all of that.

“So a major advantage of lasers is their really high resolution and total control over where the heat is going, which is really favorable in a food printing application where you have food layers that are only a few millimeters thick”

“We are shining a laser at two mirrors controlled by motors and these mirrors move really fast to create complex patterns and heating the food from below.” Complex laser beam geometry used to be a staple of holographic 3D printing except now in this case, it is being used to cook foo as well.”

“You can cook as the food is laid down layer-by-layer, which is much more effective in this context.””

Apparently the technology is pretty low tech compared to what you would expect so according to the researchers it could become available within 5 years.

He said: “If you try a meal and like it you can simply download and send it to a friend who can try it immediately.“It’s like having a personal chef who can perfectly replicate any meal.“You can also add in this machine learning AI element
