Deliverables

To-scale model with external and internal renders of watch.

SUMMARY

I disassembled a casino watch and created a 3D replica of its components to better understand how tolerances and assembly impact manufacturability. This hands-on project focused on measuring internal parts, modeling for fit, and aligning design choices with real-world production constraints. It served as a deep dive into DFMA fundamentals.

MODELING

Teardown & Analysis

Casio’s A16WA-1 watch was disassembled and measured to ensure accurate scaling. Select components were intentionally scaled up in size or thickness to enhance visibility and durability in the 3D-printed model, especially parts that were originally too thin to print without breaking.

PROCESS

Printed Components

Class A surfaces were printed with resin. Smaller parts were printed with PLA. These materials were selected for their ability to withstand the high temperatures generated during resin curing.

Sanding

Class A surfaces were printed with resin. Smaller parts were printed with PLA. These materials were selected for their ability to withstand the high temperatures generated during resin curing.

Casting
