Prototyping process:
3D Modeling
Use CAD software to design the main brace body and adjustment mechanism
We did a customized brace which began with a 3D scanned forearm as the base shape of our design.
Use the plane cut option on Meshmixer software to create a wrist brace design off of the scan
Add slots for straps along the side
Apply the Voronoi pattern using the built in feature
Export the final design as an STL file.
3D Printing
Use a 3D printer capable of printing flexible TPU,PETG
Print settings:

• Layer height: 0.2mm
• Infill: 20% gyroid
• Support: Enable for overhangs

Assembling the components
Requirements: Main body, straps
Inspect the 3D printed main body, ensuring there are no cracks or defects.
Cut and thread the straps through the designated slots on the main body.
Ensure a secure fit.

Functional trials:
Fitting and adjustments tests:
Fit the assembled brace on a user hand
Check for proper alignment, comfort and functionality
Make adjustments to strap lengths as needed

Structural tests:
Fit the brace on a user
let them wear the brace for 2-4 hours under normal activities i.e. typing, light household tasks
Record feedback on comfort, pressure points and breathability

Flexibility and mobility
Verify that the brace provides support while allowing necessary finger and hand movements
