Hi Folks,

Check out what Harry and I have been working on in the 3D printing group.

We're designing air foils that can be 3D printed.

Check out this discussion to get the Blender CAD files, and for more details:

Is the utility bar missing? I had the same problem, and fixed it by clearing my browser cache. Some bad javascript keeps getting downloaded for some reason.

Ellison, I attached that file in the main 3D discussion group area. It wont let me post in the blender parts discussion.

@Jesse the first part on the scale was actually printed with 10% fill, so it's mostly hollow. Laser cutting won't be able to do that.

If I had access to a Stratasys, I'd be printing something less boring than that. :-)

Here is a complete air frame in an article on wired.

If you're just making solid parts, laser cutting would be a far better method. Much, much faster and cheaper. You can actually compare the cost difference through a site like Ponoko.

Here's a little wing I made:

That looks great, Ellison. My imagination is going much faster than my CAD learning process.
