Overview of Status of Analysis, Design, Fabrication, Tests, etc.
3D printed out a mold and test casted PDMS. The mold leaks, and doesn't have good resolution. Also difficult to take the part out.
Caleb from Dr. Tolley's lab took a few hours of his time to show us and teach us how to cast PDMS. We put the PDMS into a vacuum chamber, and then poured it into the mold, then vacuumed it again to get out all the air bubbles for a better part.
Printed out redesigned plug. Plug shape is almost reaching final design.
