My next project (after finally finishing all the quadratic surfaces) was to make a helicoid. I spend some time on Mathematica creating different helicoids by changing the parameters of the formula. The helicoid is pararametrized by \(x=u\cos(t), y=u\sin(t),\) and \(z=u\), where \(u\in[-1,1] \) and \(t\in[0,2\pi]\).

Professor Denne and I decided to print two of the ones I created to start (we may print more!). I exported the following Mathematica files and imported them into Cinema 4D.Screen Shot 2015-07-27 at 1.01.24 PM


Professor Denne used these files (as well as others) to create another worksheet in Mathematica. It can be found here

Later on, I made another helicoid, this one with \(u\in[0.25,1.25]\) and \(t\in[0,2\pi]\). This model can be found on Thingiverse here.
