If you’ve heard older runners say they don’t have any knees left, what they probably mean is that they’ve eroded their cartilage—and once it’s gone, it’s gone. But that could soon change.

3D-Printing Entire Neighborhoods
We wrote recently about Dutch architects 3D-printing a house; after years of hype, the Amsterdam house is the first to break earth, to our knowledge.

It doesn’t sound like they printed the houses, exactly, but rather used customized printers to create “automated sprays,” according to state news agency Xinhua. In both cases, the builders said using printers allows them to waste less material, and the Suzhou company also started with reclaimed materials.

Audio speakers, with lots of moving parts, also sound like something that no one has probably figured out how to 3D-print yet. But the clever folks at Disney Research have — sort of. They can print speakers in any shape — Mickey Mouse encouraged but not required — by using electrostatic energy instead of electromagnetic energy.
