[DaveMakesStuff] demonstrates a great technique for 3D printing a sphere ... Vase (or spiral) mode prints an object using a single, unbroken line of extruded filament. The resulting object ...

Smalley's team successfully demonstrated it by projecting the static outline of a butterfly, as well as a moving spiral line drawing ... improved on other similar 3D projections' systems.

However, UGC 10043 is viewed edge-on, with its rings seemingly flattened into a line. This unique angle gives astronomers the chance to see how spiral galaxies are structured in 3D. This image of ...
