Creative advertising agency Teehan+Lax have created quite a buzz with a concept for a milk jug that can alert you when it is running low on milk. This is similar to smart-fridge and internet-of-things concepts we've seen before, however, the product itself may not be very practical for real world use.
More interesting is how the agency realized the concept by using 3D Printing. Previously, concept product images and video were likely to be rendered and would never come close to being made due to the manufacturing costs. Now, with a 3D Printer in the agency, the creative team were able to print a working example of the concept and use it in real world cases.
The result is a much more believable presentation of the concept, and I expect we will see similar uses of 3D Printing by creative teams as awareness of 3D Printing continues to grow.
