The following post is by Henry Delgado as part of George
Mason University Math 493, Mathematics Through 3D Printing.

The Lorenz attractor
is a system of ordinary differential equations (ODE), named after Edward Norton
Lorenz. Mr. Lorenz was an American
mathematician and meteorologist (1917 - 2008).
As a meteorologist Lorenz looked further than linear modeling and
started to take an approach in chaos theory (also known as the butterfly effect)
in which resembles weather patterns.
Figure 1 Lorenz attractor resembles a figure eight and figure 2 contains
the Mathematica calculation used to create the design.
The Lorenz equation
consists of three ODE. Figure 3 displays
the Lorenz equation with variables
σ, ρ, and β
σ, ρ, and β
Modifications to
each variable develops a different chaotic design. For example, calculation on Figure 4 has been
changed to (σ, ρ, β) = (-3, 26.5 and 10, 1) .
Calculation on
Figure 5 has been changed to (σ, ρ, β) = (-1 and
-3,26.5 and
5, 1).
Calculation on
Figure 6 has been changed to (σ, ρ, β) = -3,100, 1).
The below design
was created off of the MakerBot 3D 5x printer.
This model took roughly 1 hour to generate. Calculation on Figure 7 has been changed to (σ, ρ, β) = (-13 and
-3, 26.5 and
10, 1).
