So I found this article on Discovery yesterday, and I just thought it was plain awesome.
Scientists have created a 3D printer that specializes in food. Yes, food. It uses different food bases to create basic food structures that mimic the taste, nutrition, and texture of hundreds of different foods. The Fab@Home printer is being looked at by NASA to be used on the ISS to create a little more appetizing foods for the astronauts up there.
It’s not quite the replicator from Star Trek: The Next Generation, but it comes pretty close. It can’t quite print out a hot cup of Earl Gray tea, or even a steak for that matter, but it is still a work in progress and has great options for the future.
You might not be seeing one in everybody’s house soon though. Right now it is best built for extreme outposts, like the ISS or an artic outpost. The printer is not very good at making complex foods like hamburgers, or mimicking the shape while retaining the same taste. But we will have to see how this turns out in the future!
