Ian Steadman considers the copyright implications of 3-D printed food:
Imagine yourself in twenty years sitting down in your kitchen and wanting a glass of cola and a hamburger. You could download Coca-Cola’s classic recipe to go with a McDonald’s Big Mac, but you could also download that extra-caffeinated cola someone’s hacked onto the server along with a Big Mac with a particularly smoky ketchup in place of the banal, “official” version. Or you could knock something new up yourself, a drink that’s sugar- and caffeine-free and with an extra shot of vitamin B and a burger bun that’s gluten-free.
[Open-source soda brand] Open Cola can be [seen as] a first, extremely crude example of this change, in this case. Once the infrastructure for 3D printing is in place — the cultural expectation of being able to get home, slot a cartridge into the machine, and print out anything you want — then the food industry is going to struggle to keep its secrets safe.
