Spiral Fan 3D print by llewelld Spiral Fan 3D print by llewelld
Object generated using Functy and printed by Shapeways. Thanks to ~Tonyralano for prompting me to upload the images.

The object is a spherical function with the following formula:

radius = (0.01*((1+cos(12*(a+(p*2)))*sin(p))+(1+cos(3*a+p)))),

colour (R, G, B) = ((1+cos(p*2))/2, 0.3, cos(12*(a+(p*2)))>0.9).

The 3D print was created in full colour, and I'm always impressed by the quality Shapeways consistently produce. There's also a render of the object.

You can indeed :) Shapeways is a great site: just upload your models and they'll print them. Unfortunately it can be a bit pricey if you use a lot of material (if I'd been more careful with this model I could have hollowed it out to make it cheaper).

My brain is not capable of believing that this is a photograph. o_o

Thanks :) I'll take that as a positive ;) It is truly amazing what 3D printers can do now. Compared to some of the objects other people are creating this one is really very simple too.

Other than a tiny notch in the first image and some unexpected specularity in the texture, it looks indistinguishable from a 3D rendering. And I can't believe I'd never seen Shapeways before, this is my new favourite website. :D

You're right, there are some imperfections, and that notch shouldn't be there. Shapeways place certain limits on what they can print (e.g. the thickness of walls), which I ignored with this model. They printed it anyway, so I'm grateful they did and pleased with the result :)

I've spent many hours looking through the wonderful creations people have on the Shapeways site. Some of them just shouldn't be possible!
