Thingiverse superstar, Engineer/Artist Emmett Lalish shared a new design, created in Matlab. We tend to watch for what he’ll share next, given how many of his designs have wowed the entire 3D printing community from the Screwless Heart Gears to the Stretchy Bracelets to the Automatic Transmission Model.
This object was created with Matlab, and my .m script is in the downloads section. I generally use OpenSCAD for design, but these curvy forms are not well suited to it. Instead a made a recursive knot script, that builds a 3-1 knot around the path of a 2-3 knot, along which the earth rolls. Doing my own texture mapping was a new and interesting challenge.
The 3MF contains all the texture info and such. 3D Builder will open it (and hopefully more 3D apps soon as well). I work on this format, since STL and OBJ are somewhat lacking as 3D printing formats.
…I decided to branch out and try designing something for a full color powder printer. The STL really doesn’t do it justice; if you have Windows 8.1 (or 10), you can open the 3MF with 3D Builder, which I work on.
I used NASA images: the Blue Marble for the earth, and the Hubble Deep Field for the knot. The earth is forever captured, but can roll around a knot-shaped orbit. See my video of the finished print.
One of the cool features we added to 3D Builder is “Buy Print”, which allows you to make things in materials we can’t manage at home. I printed this in Colorstone for $172 (I know, not as cheap as we’d like, but pretty good for a 6 inch wide piece)….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
