Here is the Fragmentarium code to render limit set of hyperbolic reflection groups. Have fun! Vladimir Bulatov 3D graphics Researcher, http://shapeways.comhttp://bulatov.org |

Very Nice...are you producing these via Mandelbulb?

Hi Vladimir, Out of curiosity, what tool do you use after Fragmentarium? Is there a direct OBJ export? |

I only can do 2D rendering with Fragmentarium. I have completely separate code for 3D object generation. I assume, the Fragmetarium can be used for generation of set of 2D slices using it's animation mechanism. After that the set of slices can be converted into 3D object using presently existing route.

Hi!
I try to print my fractals too, but i receive error message from Shapeways - "walls <0.7mm".
How can i check my walls width?
Thx.

In Netfabb there is a measure tool but this is manual, there is no automatic check for wall thickness unfortunately. On regular IFS fractal this is not a problem, but on more complex shapes it is more difficult visually to find the thinner walls and wires.

I have painted my bulbs, they look much better like this, it really gives them life, I am very happy with the result   |

hey cool, that looks quite similar to this bulb rendering i did back in 2009  how big can such 3d printed bulbs be, and how's the spatial resolution? |

Yep, I thought about your render too The size depends on the material: http://www.shapeways.com/materials/material-optionsThere is no concept of spatial resolution, rather of level of detail, see the same link. With the standard white plastic, layers are 0.1mm thick. Keep also in mind the 1 million faces limit and the minimum wall/wire thickness that also varies by material. |

Vladimir Bulatov http://shapeways.comhttp://bulatov.orgIf you allow me I have two quick questions for you Vladimir: 1- After you upload your model, some tests are performed by Shapeways to check if the model is printable. Does Shapeways plan to make this check tool public? That would save a lot of time if I could perform the checks at home without having to upload big OBJ files. As I use a kind of dichotomy to make the thinnest possible walls and wires, sometimes I need to upload many times different flavors of the same model before I am satisfied. Removing these upload times would speed up the process a lot. 2- Do you plan to make publicly available your tool to convert voxel slices to OBJ? Today, I think Fiji is the only (not too complex) solution. It works, but I would be interested in testing other methods. As a side note, for those who use Fiji, I advise to test a resampling factor of 1 instead of the default value of 2 when you save as OBJ. It gives much better results especially if the voxel is not too big (say less than 200x200x200) and the shapes very geometric and regular (squares, triangles...) |

Hopefully some better tools will be available on Shapeways site soon, but I can't make exact promises. I perfectly understand the difficulties you encounter and in our best interest is to help users. 2- Do you plan to make publicly available your tool to convert voxel slices to OBJ?
I don't have such standalone conversion  . I use the abfab3d library directly from my modeling code. Vladimir Bulatov shapeways.combulatov.org |

Just received my first fractal metal prints ordered from shapeways. After running 24 hours in a tumbler with steel shot they came out just perfect! The pieces are 5cm in diameter. Vladimir Bulatov http://shapeways.comhttp://blatov.org |
