Mandelbulb - Arrow Pyramid Fractal by Amygdoloid

Last crawled date: 3 years, 4 months ago

Hi there,
here is a 3D Fractal. It is one half of a "Bulb", so it can be printed without supports. It is pretty Hard to grasp the shape on one or two photos. Have a look at the .stl file to get a real feeling for the shape. To me it looks like arrows forming a Pyramid.
Design
The Fractal is made with - Mandelbulb 3D
get this fascinating piece of opensource software at: https://www.mandelbulb.com/
Julius Horsthuis, Hal Tenny and Don Whitaker have many good Tutorials (Video & Blog) to get started with Mandelbulb.
-This fractal is based on the "Octokoch" formula. I've added the formula Parameters, you can download them and tinker around yourself.
It is exported with "BTracer" as .obj with a volumetric resolution of 600 x 600 x 600, this is so high because only this way you get really sharp edges.
Postprocess
The postprocess is done with Meshmixer and Blender.
Meshmixer:

Scale the model to the size you like


Add a horizontal plane cut to have a plane surface for printing

Reduce at least by 50%
The last tep is optional, but I like to do it. To reduce the Triangle count and smooth ot the surface I take the model to Blender.
Use the decimate modifier to get the triangle count further down. For some reason sharp edges get preserved better in Blender when reducing the amount of triangels drastically. At least I llike the results in Blender much more. If you dare you can use the smooth modifier, but be really careful with the parameters.
Finally export your model and sclice it.
That's it. Leave me some feedback and please post your makes.
