Normally one makes solid objects with a 3D printer, but how about making balloons? Yes, real, floaty inflatable balloons. That's now possible, according to New Scientist, who reported on developments at the Swiss Federal Institute of Technology.
The trick is that they don't 3D print the actual balloons. Instead, they design and 3D print customized molds in which the shaped balloons are formed using traditional methods.
This technique should permit the creation of a wide array of new and hopefully crazy balloons. One can imagine a customized balloon shop able to produce artistic products or specialized balloons on demand.
