Topology Optimization of a Retainer to Reduce Mass and Increase Stiffness in the Drive Direction
Original Design:

The original design consists of a V-Shaped Profil that holds a diaphragm, and a Ring connecting the retainer to 4 driven carbon fiber rods.
- Material: Nylon PA12
- Process: 3D-Printed (SLS)
- Weight: 1.52 g
- max displacement: 0.7mm
Improved Design:

It was found that only two of the carbon fibre rods need to connect to the retainer resulting in a significantly lighter overal design. The shape is optimized for minimal compliance.
- Material: Nylon PA12
- Process: 3D-Printed (SLS)
- Weight: 0.41 g (reduced by 73%)
- max displacement: 0.01mm (reduced by 98%)
