It’s annoying when there’s nothing you like left in the vending machine. But who knows, in the future, we may be able to choose a customisable snack. VTT Technical Research Centre, based in Finland, has been experimenting with 3D printing to create a smart vending machine.
The machines would work by letting you select from a variety of textures and flavours before printing off your custom-made snack.
While smart vending machines would offer the potential for healthier snacking, it doesn’t look like they’ll be dispensed any time soon. For industrial scale production, researchers still need to discover the perfect ingredient mix for the printing process.
So far, snacks have been made using starch and cellulose-based products. Researchers are now looking into printing off protein concentrates from plants such as oats, fav beans, and whey from dairy… a whole new meaning to Frankenstein food.
