Mandelbulb - Arrow Pyramid Fractal

prusaprinters

<p>Hi there,<br/> 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.</p> <hr/> <p>Design</p> <p>The Fractal is made with - Mandelbulb 3D<br/> get this fascinating piece of opensource software at: <a href="https://www.mandelbulb.com/">https://www.mandelbulb.com/</a></p> <p>Julius Horsthuis, Hal Tenny and Don Whitaker have many good Tutorials (Video &amp; Blog) to get started with Mandelbulb.</p> <p>-This fractal is based on the "Octokoch" formula. I've added the formula Parameters, you can download them and tinker around yourself.</p> <ul> <li>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.</li> </ul> <p>Postprocess<br/> The postprocess is done with Meshmixer and Blender.</p> <p>Meshmixer:</p> <ul> <li><p>Scale the model to the size you like</p> </li> <li><p>Add a horizontal plane cut to have a plane surface for printing</p> </li> <li><p>Reduce at least by 50%</p> </li> </ul> <p>The last step is optional, but I like to do it. To reduce the Triangle count and smooth ot the surface I take the model to Blender.</p> <ul> <li>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.</li> </ul> <p>Finally export your model and sclice it.</p> <p>That's it. Leave me some feedback and please post your makes.</p> <h3>Print instructions</h3><p>-Prusa Mini<br/> -0.2 mm Quality</p> <ul> <li>Prusament PLA</li> </ul> <p>Filament: Das-Filament, Grün gold</p>
