Space Station Torus - Ver 1 shown in this link below as evaluated by NASA.  

This torus example has a small radius and if spinning once per minute would produce a small G (a milli-G environment).  But this is fine.  Most experiments involve a micro G environment.  A mini G mode may help with cleanup and a little comfort.

To compare this to on 3-D Printing or Additive Manufacturing, the voxels in this example are approximately X= 2 cm, Y = 4 cm, Z= any length,.  The key feature is that each extrusion may bend and twist and slide.

As air pressure inside increases, the extrusions are pressed together more firmly.  Redundant methods can seal the structure.

There is very little delaminating force.  Forces are distributed evenly.

This is a new way to make a pressure vessel.  It does not need thread windings like balloons and is very rigid so would not deflate.
