I'm an aerospace engineer, and a few years back I took up 3D printing as a hobby. I taught myself OpenSCAD because it made more sense to me than regular CAD. I designed some fun, mostly mathematical sculptures and mechanisms and posted them here. Somehow that lead to a sudden career shift, from designing drones to working on 3D printing at Microsoft.
Currently I write geometric algorithms, guide the development of our home-grown slicer (you can try it if you plug&play a Printrbot Metal Simple on Windows 8.1), and design the UX for 3D Builder (our free get-started-with-3D-printing app: http://www.aka.ms/3dbuilder), among other things.
I'm pretty excited about our latest 3D Builder release, since we just added 3D scanning with a Kinect v2! See our video here: http://www.youtube.com/watch?v=nXbDkJ7cRrA
My doctorate is in control theory, and if you're interested, you can find all my research publications and dissertation here: http://www.aa.washington.edu/research/ndcl/publications.html
