We’ve talked about 3D printed food before, but this one caught my eye.  My wife and I went to Australia for our honeymoon and of course when you’re down under trying Vegemite is a right of passage of sorts.  Being a paste it’s well suited for extrusion, but what was interesting was how its yeasty salty goodness could create circuits that conduct electricity.  I guess this is also further proof that people will try to 3D print everything eventually…
