       | This is actually kind of an awesome idea, printing overhang has

       | the major slicers soon.

         | The big issue that I have is that the orientation of the layers
         | determines the strength of the part. Any vertical tension pulls
         | the layers apart, so sometimes I wish I could somehow print a
         | part in two orientations to make it stronger...

       | The core idea is basically the same as that of the Nubian vault,
       | so the core idea is very ancient. One can do this with snow too,
       | to build somewhat surprising structures without having to use
       | supports.
