Many have been printing toys and parts with 3D printers for years already. You can do a whole lot more with the top 3D printers of today though. Take this 3D printed lounger chair for instance. It was created in a single print on the ProX 950, with the design inspired by nature. The chair was 3D printed with less material and is lighter than comparable 3D printed chairs.
The above video gives you a better idea how this 3D printed chair looks. As you can tell, it is possible to use this approach to reduce 3D material usage while printing elegant, lighter weight objects.
