Coffee Tumbler

This project explores the design of an insulated coffee tumbler focused on improving user comfort and thermal protection. The objective was to create a form that is easy to hold while incorporating a secondary insulating layer to reduce heat transfer to the hand.

The development process was driven by hands-on material exploration and thermal performance considerations. Research included evaluating a range of materials—such as ceramic, stainless steel, glass, plastics, and paper-based options—as well as forming methods and mold strategies. These insights informed both the structural design and material selection approach.

Final Prototype
A full-scale prototype was produced using a Formlabs 3D printer. While the intended production material is polypropylene, the printed resin was selected to approximate the properties of ABS for functional evaluation. The design incorporates Buna-N O-rings as grip elements, enhancing ergonomics and thermal separation.

The final prototype allowed for assessment of form, grip comfort, and overall usability, supporting further refinement toward a production-ready solution.
