Nautilus Shell Cross Section

This cross-section model of a nautilus shell demonstrates one of the nicest natural examples of a logarithmic spiral.

Print as oriented to get nice, crisp lines on the inner chambers. Raise the model off the build plate 3mm or so and generate tree supports underneath to support the contoured bottom surface.


Chain Link Klein Bottle

This model uses chain link latticing to represent a three-dimensional approximation of the four-dimensional “Klein Bottle.”

The concept of a Klein bottle was first described in 1882 by the German mathematician Felix Klein. It is a closed non-orientable surface that has no inside or outside. It is similar to the Möbius strip, but unlike the Möbius strip it has no boundaries and cannot physically exist in three-dimensional space.

In this three-dimensional representation, the surface intersects with itself, but in four-dimensional space the self-intersection can be eliminated. Unfortunately, I don’t have a 4D printer yet.

Modelling this intriguing shape in chain link latticing allows for visualization of the whole surface.

The small spiral has six logarithmic revolutions; the large spiral has ten logarithmic revolutions.

Large:

Print as oriented with the larger end down. Raise the model off the build plate about 3mm and generate tree supports underneath. It is best to print at least two at a time for best results.
