To construct the coolest new thing in 3D printing, just add water.
Tokyo-based advertising agency TBWA\HAKUHODO created the most gorgeous ice cubes you'll ever see. It's all part of an ad campaign for Japanese Whisky, and it recently won 6 awards at this year's Asia Pacific Ad Festival (commonly know as AdFest) in Thailand.
Technically, the creation of these tiny ice sculptures is more like "3D milling" than 3D printing, according to the ad agency's website, but the concept is similar. Rather than building up an object from layers of plastic, the 3D mill shaves the ice away to create a desired shape. Like a 3D printer, the 3D mill is connected to a computer and even uses a 3D-printing app.
The only thing we don't love about these ice cubes is that they melt.
Here's a video of the 3D mill in action:
