3/21/17 - Airfoil Results and Full Model

The print of the SD7037 airfoil () has finished. It printed more accurately than I was expecting. I oriented the shape vertically so any stripes from layers would run with the direction of airflow. This method of manufacturing airfoils is effective for prototyping, but I will try something else for the final test models.

For the next model, I will try to use the laser cutter for greater precision and some flexibility in materials. I also have more experience with the laser cutter. A possible solution is to cut multiple profiles of the airfoil out of a sheet of chip board along with holes for alignment. A dowel through these holes will allow proper alignment, but this might not be necessary.
