Hyperboloid Cup

Hey there, wonderful people!

I really like the idea of producing different inner and outer surfaces in vase mode prints!  The concept is reasonably simple, really - just manipulate the outer profile such that it wiggles its way into the interior and effectively draws a shape in there, then returns to the outside world again to continue tracing out the outer shape.  Some of the screw-top vase mode containers I've done in the past work this way, though this one is somewhat more convoluted.

The Hyperboloid Cup's exterior is tiled with diamonds that are distorted into larger shapes at the top and bottom by that hyperbolic curve, and rather than just being a texture on the surface, the diamonds are outset from the body, so that the edge points are actually very slightly flexible.  Meanwhile, the interior has panels running vertically, and that was ultimately what I wanted to achieve - distinctly different patterns on the inside and outside despite the thing being vase mode!

Print Description

The Hyperboloid Cup is a vase mode print, so set your slicer accordingly!  

This one was designed for, and tested at, 0.4mm line width, but the tolerances are quite generous anyway.  However, if you are going for larger line widths, bear in mind that there are lots of back-and-forth lines in there, and there may come a point where you might start getting slicing oddness if broad lines effectively overlap.  The slicer will probably highlight such an instance, though, as changes to the profile will affect the layer above.

Print Dimensions

By default, the Hyperboloid Cup is 80mm x 80mm on the print bed and is 87mm tall.

Supports Needed?

Not at all!  Designed for straightforward printing!

Scalability

As a vase mode print, this one will scale just fine!  

That said, if you're scaling down you'll want to check that the slicing looks sensible, since at some point the gaps between lines will get small enough for the slicer to start skipping bits - it's the same consideration as using a wider line width at standard scale, really! 

Print Orientation

As tends to be the way with vase mode prints, this one prints right-way-up.

Further Thoughts

This print actually started life as a two-piece thing, with an inner that screwed into an outer, but at some point I decided that this particular model would look better as one single piece.  Having vase mode parts that thread together was definitely cool, though, and still required the same techniques that were used on this one, and maybe that'll resurface in a different vase mode design :)

Happy printing!
