Gear for mobile chair
What we did?
- CAD Design (based on the broken part)
- Nylon (MJF PA12)
Instead of replacing the entire motor subassembly due to the broken part, we modelled a new gear based on the existing part using CAD and 3D printed it in nylon (PA12) using Multi Jet Fusion (MJF).
The resulting in a strong and durable gear (a conclusion we took by testing the functionality of the part).
This procedure can be made for any gear.
