Attenuation Vase (Patreon)

Howdy, wonderful people!

Ripples on water are mesmerising, and you will not be surprised to hear that that's exactly what inspired this design!  How, I wondered, could one construct a form that gives the impression of ripples along it, fading away by the time they reach the top?

This one was entirely devised in code, using OpenSCAD and lots of poking and prodding at trigonometric functions.  The attenuated ripples are just peaks in a sine wave that adjusts the profile of the vase, and which are reduced in amplitude in direct proportion to their height on the vase.  

There was some trickiness to keep the overall shape robust, though.  Usually, I'll incorporate vertical elements to vase mode prints in order to add strength, but doing so on this one immediately detracted from the visual effect of the ripples.  Instead, I started experimenting with different initial amplitudes to find a good balance between the prominence of the ripples and the bond between the layers.

Print Description

This is a vase mode print, so set your slicer accordingly!

If you want to improve the strength of this vase you might like to increase your extrusion width a bit, or even swap to a larger nozzle.  Another option is to use a pseudo-vase mode by just adjusting a regular print to have zero percent infill, no top layers, and then setting the number of perimeters to whatever provides the strength you're after.

Print Dimensions

The default size of the Attenuation Vase is 85mm x 85mm on the print bed and 180mm tall.

Supports Needed?

Not at all!  Designed for straightforward printing!

Scalability

As a vase mode print this will happily scale up or down!  I actually prefer it at 50% scale!

Print Orientation

As you might expect, the vase prints right-way-up, like so:

Further Thoughts

These ripples are purely linear, making an adjustment to the overall profile of the vase, but it would be amazing to do something similar with concentric ripples, radiating out from a point....

Happy printing!
