A Sierpinski tetrahedron, the 3D version of the Sierpinski triangle, stage 5. There are 4096 of the smallest triangles and 1024 of the smallest tetrahedrons. The model has 499994 faces.

The sides are 17.8 cm (7 in) long and it stands about 14.5 cm (5.7 in) high.

The pictures of the blue model are of a previous smaller version, the pictures of the white and the black model are of the current version. Thanks to @zeromangahunter for the pictures of the white model, I couldn't find out who made the pictures of the black model, but thanks anyway!

I created the model using POVray and MeshLab.

That's a lot of Triforce for one person.

@bigred286 It was a color called "jeans blue" which was offered by shapeways at the time. Sadly colors are no longer an option for this model as all colors are polished and the model is too big for polishing. On the shapeways forum there is a section called Post Production Techniques which has lots of info on dying white WSF.

@Wahtah I'd love to know how you colored the WSF blue. It's a fantastic shade!

@Wahtah : You're right, I'm sorry. I just thought that doing that would give a cool light & aerial look to this structure.

@ttoinou or maybe it's cheaper because you left out two levels?

I made my own Tetrahedron with only thin wires so it is way cheaper, check it out (: .

@ZAKI yes it is plastic, it is made by melting nylon powder with a laser

woow !! looks great , what kind of materials is made of ?? is this plastic ?

It would be very difficult to print on the "regular" type of 3D printer, the type which melts plastic filament. But this is printed by melting a pattern in a box full of plastic powder with a laser, then adding a new layer of powder, melting the next pattern to the previous, etc. The unmelted powder supports the model during the proces. Google: "selective laser sintering"

Nice model and it looks good in blue. But I don't understand how can it be printed... Each pyramid lies on three others pyramid's top vertice, so they must have added some removable (and removed) wire to support it !

Go ahead, make my day :) Update: also removed frosted detail materials from the list, so now it's just strong and flexible...

Put me down for one. No, make that four. Actually... 16.

Never mind, the question has been answered: the order in the Detail material has been rejected. I've removed these options from the list.

I just saw someone ordered this in Transparent Detail, I would love to hear how that turns out, so if you happen to read this, please let me know!
