Sortera det här under mer spekulativa framtidsscenarier:
När butikshandeln till stora delar ersätts av näthandel finns restaurangbranschen kvar som tillflyktsort för okvalificerad arbetskraft. Men vad händer om 3d-printade måltider blir verklighet? Troligen kommer människor alltid att vilja laga mat "organiskt" och restauranger erbjuder förstås mycket mer än bara mat, men för vissa konsumenter lockar det nog att printa ut en måltid designad av valfri Michelinrestaurang i det egna köket.
He sees a day when every kitchen has a 3D printer, and the earth’s 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor’s vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.

Pizza is an obvious candidate for 3D printing because it can be printed in distinct layers, so it only requires the print head to extrude one substance at a time. Contractor’s “pizza printer” is still at the conceptual stage, and he will begin building it within two weeks. It works by first “printing” a layer of dough, which is baked at the same time it’s printed, by a heated plate at the bottom of the printer. Then it lays down a tomato base, “which is also stored in a powdered form, and then mixed with water and oil,” says Contractor.
