A 3D printer that could use a 'feedstock' to print a variety of foods would be fantastic. Especially if the feedstock had a long shelflife with no refrigeration. Something like a can of cooking oil perhaps? The next big thing will be when a 3D printer can print another 3D printer. Self replicating. Given that we'll enter into a 'society of abundance' where anything that can be printed will be available for the cost of raw materials and power.
That will change everything.
Not sure about cooking oil because i can imagine that that it might be hard for it to solidify as a part. What might be possible is printing a bottle and filling cooking oil in it at the same through different extruders. And yes, it is an exciting field and i am always reading about it.
I didn't mean cooking oil as such. I meant 'stored in a package needing no refrigeration' similar to cooking oil. I'm sure it would have to be a special feedstock containing all the nutrients and vitamins that the body requires. Obviously cooking oil does not have that.
sorry did not get it the first time. now i got it. sure, it is most likely formulated as a special feedstock before flowing out from a nozzle. Just wondering how they are going to do that. I guess the food science people will do it quite well
