3D printing could be key to creating authentic-tasting cow's milk, without the cows

3D printing has a whole host of use cases, but one that you might not previously have thought of is the use of additive manufacturing to create cow’s milk — minus the cows.  That’s the mission statement of a startup called Perfect Day Foods, founded by two twenty-something biomedical scientists. The firm has so far raised $4 million from investors. Perfect Day’s plan? To create a lactose-free milk substitute that’s a whole lot closer to the real thing than existing milk substitutes.
