iPad Modeling –> Replicator Workflow
Thingiverse just featured this incredible MakerBotted model of a root structure. Thingiverse user TSDF used the iPad app iDough to model the shape above. I can’t explain the coolness any better than he did.
25 years after art school, 22 years after learning CAD, and 10 years after learning gcode, I would have never conceived that it would be possible to model complex organic geometry on a handheld device and hold a physical output in my hand 90 minutes later at such a low cost.
The app is $6.99 but holy moly does this look well worth it. It has brushes to “push, pull, smooth, move, pinch, spread, [and] flatten” your virtual clay. You can export your .obj from the app (email it from your iPad to your computer, says TSDF), and convert to an .stl in Netfab.
