3D-printed, laser-cooked chicken meat: this is how these researchers see the future of meat

The laboratory meatLike it or not, it is succeeding more and more. Presented as an alternative to the high resources consumed in livestock, it has been monopolizing the market in recent years from hamburgers to sushi. One of the methods to obtain it is to print it with a 3D printer. And to cook it? Goodbye skillet and oven, welcome laser.


To print fake meat with a 3D printer it is relatively easy, given the precision of these machines it is possible seamlessly recreate all kinds of shapes, including a steak. The problem comes when it comes to cooking it, it does not behave in the same way as traditional meat. The industry is trying to change that, and lasers may be the solution.

Pass the meat through The iron the laser

A team from Columbia University has come up with a solution for cook 3D printed meat better and that it has an appearance, flavor and texture similar to the traditional one. To do this, they heat the chicken through laser pulses.

Researchers they first created a “chicken meat puree” that later a 3D printer printed to give it different shapes in different samples. Keep in mind that for the experiment they used real meat that they first mashed to puree. The idea is to use any type of meat that is 3D printed.

Subsequently heated the samples with a laser that sent pulses of light to stir and thus heat the meat. The process takes between five and fourteen minutes. After tasting this coveted meat with laser and traditional methods, they indicate that laser cooked is preferred. As a result, the meat retains more liquid and gives off a greater flavor than other methods such as roasting the meat in the oven.

According to the researchers, the trick is in emitting the laser pulses at different wave amplitudes and directing them along certain trajectories. For example, a blue laser penetrates better to cook meat on the inside, while an infrared laser is useful for browning meat on the outside. They can thus heat and cook 3D printed food more conveniently.

The long-term vision of the research team is that in the future anyone can have access to food printed in 3D and each one print the shapes and combinations you want, as if they were “recipes”. The pioneer company in this is indeed Spanish. But if the creation of food evolves, the way we cook it must also do so and adapt. In that future, the laser has more ballots than the frying pan.
