At the beginning of the Covid-19 pandemic, I was no longer able to buy bubble tea from the store. I began making the drink at home by making dough and hand rolling the tapioca pearls, but this was very time consuming to do. To maximize the efficiency of rolling the pearls, I designed and fabricated a rolling tool that would roll 20 pearls at once. I used SolidWorks to create a 3D model of my concept drawings, which I then 3D printed using the printer I built. I printed mini prototypes to verify dimensions before printing each part in full size. The Tapioca Pearl Roller reduces the time to roll enough pearls for six drinks from 2 hours to about 20 minutes.
