Floating Wind Turbine

Engineering Grad student Sara A. and club member Curtis S (assistant to Sara A.) are designing a floating wind turbine with free-moving sections.

- Problems and Solutions

  • Wall thickness for 3D printing  - its best to create wall thickness that is a multiple of the nozzle, in the case of the Ultimaker it is .4 mm, thus a wall thickness of 1.6mm was chosen.
  • Chamfered edges to eliminate the need for support structures. - With overhangs, if acceptable with the specs of the project, it is best to use chamfered edges.
  • How to join each shaft section do they could rotate freely from one another - by using chamfered edges, more surface area is present to glue bearings between turbine shaft sections.
  • Making sure to boolean union inner rings to outer rings for 3D printing.
  • Creating sections that fit within the build volume.
