Imagine this. You walk into your kitchen. Instead of getting out your pots and pans, you turn on your printer. You flip through a few recipes, then find the perfect one. Now you load ingredients into the machine and wait for dinner to print.

Food printers work like other kinds of 3D printers. They print layers of material on top of each other until a finished product pops out. But with food printers, all the material is edible.

No one is sure yet how 3D printers will change the way we eat and cook. Will they work best for restaurants, or for home cooks? Will people one day print all their food, or just some of it?

But people have all kinds of ideas for the new technology. They are already planning pastries with specified nutrient levels, ravioli that assemble themselves, and wedding cake toppers that look just like the bride and groom. One company has already designed a machine called the ChefJet Pro, which prints in sugar. The same company has a chocolate printer called the CocoJet.

God gave people the ability to invent new things—even food printers! If you had one, what would you print?
