Scarab is finally here! Few people have ever been so enthused about a dung beetle as yours truly.
This is my first 3D model (after the tutorials) and first Shapeways print of my own work (though I did some
testing in advance). I'm thrilled with how it turned out.
The goal is to make a biological artifact, something recognizable, even cliche, that can still generate a little surprise. Judge for yourself.
The design is original and all-manual, built from primitives in Blender (no scans).
The current print is a test for a more ambitious piece with moving parts. I hope it's a good example of what the technology is capable of. The printer, the technicians, and the customer service folks did a marvelous job, which makes me excited to push on -- thank you, Shapeways!
Some observations for designers (no real surprises):
- Anything with a clearance of less than about 0.5mm fused.
- The hind claws taper down to points that can easily pierce flesh -- the resolution on the machine is sensational -- and survived the polishing process, despite being no more than 0.2mm thick at the tip. I count myself lucky here; had the claws broken, it would have been my fault.
- Little bits of orangish support material are wedged into various cracks and crevices. Will take some detail work with a needle to get it out, but it's only noticeable from right up close.
- The head shell was not actually attached to anything in the model, but had clearances of less than 0.5mm all around and fused with the thorax shell. It appears to have settled a bit, hooding the eyes more than I'd intended. I'm going to put a strut in the model to try to more directly enforce relative geometry.
- The piece is hollow, but it's nice and heavy. Feels, uh, real.
- The printing layers are fairly obvious at this scale. I intend -- if I can get my courage up -- to sand and polish the outer shell. We'll see.
I've uploaded a
revised model so that others can enjoy this little scarab if they like. (If you think there might be a market for such a thing, let me know!)
