Finding the perimeter can be solvable through exponential notation, though I do need to research more and understand why\/how that&#8217;s possible. In simpler terms, according to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Sierpinski_carpet\">Wikipedia<\/a>, the Sierpinski Carpet is created by cutting a shape into 9 sub congruent equal squares, and then removing the middle square. This is a similar design technique to the Sierpinski Triangle, which involves a similar process but for triangles, or the Menger Sponge, a 3D cube version of the Sierpinski carpet.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-847\" src=\"https:\/\/geekhaus.com\/math103_fall2017\/wp-content\/uploads\/2017\/09\/9b522555ca1fe57584d442bfb4ff7a9a_preview_featured-2-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/geekhaus.com\/math103_fall2017\/wp-content\/uploads\/2017\/09\/9b522555ca1fe57584d442bfb4ff7a9a_preview_featured-2-300x225.jpg 300w, https:\/\/geekhaus.com\/math103_fall2017\/wp-content\/uploads\/2017\/09\/9b522555ca1fe57584d442bfb4ff7a9a_preview_featured-2-326x245.jpg 326w, https:\/\/geekhaus.com\/math103_fall2017\/wp-content\/uploads\/2017\/09\/9b522555ca1fe57584d442bfb4ff7a9a_preview_featured-2-80x60.jpg 80w, https:\/\/geekhaus.com\/math103_fall2017\/wp-content\/uploads\/2017\/09\/9b522555ca1fe57584d442bfb4ff7a9a_preview_featured-2.jpg 628w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>I would like to try using this <a href=\"https:\/\/www.thingiverse.com\/thing:1562255\">Sierpinski Carpet design<\/a>\u00a0by Chevron42 for my first print.

The fractal printed on the Ultimaker without error or fault. It took about 50 minutes in total (to create, mold, heat, cool down). Compared to other fractals in my group, I believe mine printed the smoothest and the most efficiently (the design is pretty simple after all). I am very proud of the fractal I printed. In addition, I was reading more into the Sierpinski Carpet, and I found out that the fractal has a special relationship with Brownian motion (the seemingly-random motion of gas and liquid particles hitting each other in a space). According to Wikipedia, the Brownian motion on Sierpinski carpets actually diffuses at a slower rate than an unrestricted random walk (Brownian motion).
