Snake ring - I totally didn't expect this to work by Athey Snake ring - I totally didn't expect this to work by Athey
I TOTALLY did not expect this to work as well as it did. And as you can see, it didn't even work that well - lol.

This was a test of the size, more than anything else. I won't actually wear this ring, as there's just too many little things wrong with it because of the material and the fact that it had to be printed with full raft, and simply because of the level of detail my machine is capable of is limited.

Still - it worked better than I thought it would. heh.

I modeled the ring in zbrush from nothing. Zspheres around a cylinder as a guide and so on until I ended up with the picture shown bottom-left.

My plan is to put it into shapeways so it can be printed in metal. I'll scale it down a bit more though, since I want it to fit my ring finger, not my index finger. =P

Printed with my Makerbot Replicator
:icon3dprinters: for info, if you don't know what that is.

Layer thickness .1mm

I made the file for this available on the thingiverse here - [link]

And on shapeways here - [link]

i actually did a test like that last may. i sculpted [link] in z brush and then made a 3d print out of it, i do not own the printer tho. i had to scale my piece down because it was getting too costy. [link] . I study jewelry so i cast the 3d print from a plaster mould afterwards.

hmm doubt that shapeways metal will be able to pick up that tiny detail. Even their FUD would have trouble. cool design though.

Um I know you probably don't have time for it because of your work, child and own tests but... Would it be possible that you made a tutorial on ring workflow from Zbrush to shapeaway?
I really want to print this ring I've design and sculpted on Zbrush as B-day gift for my friend but I'm horrible with retopolgy and don't have money to really make multiple tries with Shapeaway..

As for your actual ring: I think it looks very neat and tidy albeit I would have not made the tail reach out so far from the main body. It looks kind of off to me but it's a personal preference I suppose.

I didn't do any retopo on it, I just descimated it until it was under 100k points. Zbrush's STL exporter is totally innacurate as far as I can tell, with my machine. I don't understand it's scale settings, but they don't actually print to that size, whenever I export an stl directly out of zbrush. So I export it as an obj file, open it in Maya and get the scale set there - it's real world scale, so mm are mm, inches are inches.

I use this plugin for exporting STLs out of Maya - [link]
Once it's installed, you just go file > export selected, and Stereolithography is one of the options in the file format list.

Shapeways requires files be under 64megs, and after I'd run the model through descimation master and got it under 100k points, the exported stl was only like 30mgs, so it uploaded fine. 3D printers don't give a shit about clean topography, so long as there's nothing intersecting, and the mesh is watertight. I didn't have anything with intersecting geo because after I did the adaptive skin and converted the zspheres into mesh, I also made it a Dynamesh (with a resolution of at least 512 for detail) for the first bit of the sculpting, which is the best way I've found for anything to get converted into a watertight mesh with no holes or intersecting bits.

Can I favorite comments? o .o

Few questions, though, is 100k a limit for shapeaways hardware or just something you aimed for? If 100k is roughly 30mg's couldn't you have had 150-200 points? As for intersecting that should be something I can handle..

As for actual ring, it will be rather linear with very sharp clean lines on the actual ring and bit softened on a square shape at the front were I carved some sculpt. I made the base from a cylinder in Maya and imported from there to Zbrush (because I'm quite unaccustomed to working with that kind of shapes in Zbrush... I need to watch more of those car modeling videos) at first I was quite worried because the cylinder gave quite bad topology on some parts but... if it's going to be okay as long as it's tight and doesn't overlap it should be okay.

I'd done a descimation on it and got it down to something like 300k points and did the whole export thing without really thinking about how big the file was. I went to upload it and it had a little fit over the file being too big, so I looked and - yup, it was like 120mgs, so obviously over the 64mg limit. After that, I just went back and descimated it until I couldn't descimate it anymore without losing detail and exported again. When I was done, it was well under the 64mg limit.

3d printers don't give a crap about how nice your topology is, so that really isn't something you have to worry about.

It's really well-done for being something so tiny! o_o

Do you really have no need for it?

It's mostly just that it's got all sorts of jagged bits and little squirly parts that didn't print so well - heh. Still - like I said, it came out better than I expected. I didn't think the tail would print at all, but it's surprisingly solid.

It's kind of screwy, because one side came out really really smooth, but the other side has all sorts of spaghetti mess along the outer edge. The inside is just a mess by default, because I had to have inner raft turned on to support it as it printed.
