Endangered Species: Rhino by AK_Eric Mar 6, 2013

Featured Thing!


I got the idea to model the bust of a rhino, and print it in a "wireframe" style like I'd done with previous designs. This one is produced with a different wireframe creation technique however, where I instead generated blobby particles along the polygonal edges, and converted the results back into polygons.

I tried to minimize overhang issues by tracking the angle of the edges via a Python script in Maya. Very little cleanup was needed after print: No raft or support material needed.

The frame is actually a pattern I drew on some scrap MDF (nothing 3d printed there) , jigsawed out, and then routed the edges plus slapped on some white paint. Print is affixed via epoxy.

The rhino I painted red on the inside, and sprayed rubberized black undercoating on the outside.

Alternatively, some people see a penguin walking up the wall. Once you see it, you can't unsee it....

No sanding or anything: Spray-painted the whole thing red (Rustoleum), then after that dried shot the rubberized under-coating (any auto-parts store) on it as an experiment. PLA takes spray-paint just fine with no priming. Don't be afraid, just aim a spray-can at it and have a go! ;)

Sure, what I mean is;
Did u sand it? Undercoat it? what sort of paint? Brush or spray? I'm in mechanical engineering, so I can fix anything that breaks on my machine but haven't got a clue when it comes to painting and post-processing of finished parts!

Glad you like it ;) I'm not sure what you mean by the 'type of prep' I used... can you ask that differently?

Aaaahahahahaha!!! The Penguin and the fact that "Once you see it, you can't unsee it".

I looked at the pic again, saw the penguin and just imagined you walking into your home every day, muttering "...it wasn't MEANT to be a penguin... it IS a rhino... really... it is..."

I love it! Rhino, penguin, it's awesome :-) makes me wish I had a bigger reprap tho! I'll post pics if I can get one to print successfully!

What sort of prep did you do for the painting? Came up great AK_Eric ;-)

Has this been printed in wood? I would love to see that. I might buy some just for this print!

Can't wait to see it if you do ;)

Are you familiar with DotSan's work? http://www.shapeways.com/shops...

Ah hah! I ran across his work once, saw the wireframe animals, though that was really cool. When I decided to try my own hand at it, I went looking for his art again, but couldn't track it down. Thanks for the link. Safe to say I think his stuff is inspirational :)
