Created a helicopter rotor with four different wings and a hollow rotor hub in the 3D printer
More Grasshopper Fun
Spent most of my time using Grasshopper to create a parametric design within Rhino that I could 3D print. Looking into the different angles of attack of each blade and the aerodynamics of each design. The idea was to explore the different blade designs on one model for my final project. You can download the grasshopper file below and change the sliders to make different AoA. Used an extrude taper grasshopper code from this blog post.

Here is the picture of the four different blades and their different AoAs.
Here is rhino file that was created. Had some issues where I didn't make it a watertight solid, but fixed that.
Download the Rhino File:
Used the ZCorp powder printer because the ABS plastic printer was down in the Arch Shop. But if I am honest -it was really dumb luck. I thought I was uploading my file to the plastic cue, but sent it to the plaster!
Download the STL File that was exported from Rhino:
Here is the picture of the final product. If you look closely, you can see the different AoAs and also see the hollow interior that would only have been possible with 3D printing.
