3D Printing and…Milk?

In the United States alone, over 20 billion gallons of milk are produced each year. As they say, milk builds strong bones! As anyone who has ever drank milk is well aware of, the one limitation plaguing such a healthy and refreshing beverage is the fact that it spoils after just a few weeks. And as someone that has accidentally drank spoiled milk once, I can fully attest to the issue. Recently, Erik found a very interesting article about how 3D printing may solve the inconvenience of milk spoiling. Researchers, utilizing 3D printing, have developed a sensor that senses the quality and freshness of the milk inside of a carton. The sensor functions by detecting a change in electrical signal associated with a growth in bacterial population.
