For most of humanity, we’ve considered the issue of world hunger pretty much impossible to solve. That might be about to change though, thanks to Anjan Contractor’s 3D food printer. Contractor is a mechanical engineer with a background in 3D printing, and recently received a $125,000 grant from NASA to replicate his universal food synthesizer. The inputs to this machine would be different forms of powder. This would have several advantages. The powder is shelf stable for up to 30 years, so each cartridge could be fully exhausted before being returned, meaning no waste necessary. The powder also gives flexibility in producing the necessary calories for consumption, since any organic molecules can be input into the powder.
Contractor says that our current food system will not be able to support the population when it maxes out at about 12 billion near the end of the century. Therefore, we have to reconsider what we call food and take a new approach to food systems. Pizza would be a good candidate for 3D printing because it could be printed one layer at a time. Contractor plans to begin building the “pizza printer” within two weeks. The prototype for the food printer that earned Contractor the NASA grant, was the chocolate printer. This can be seen in the link down below. Recipes will be able to be traded directly as software, with the instructions telling the printer which cartridges to mix with which liquids and how fast.
