These screws feed thermoformed cups into the printing machines. The pitch of the teeth is what determines the rate of speed at which the cups are fed. The purpose of this project was to find a new pitch that would reduce the frequency of cups jamming. By 3D printing the part instead of going to a tool shop, we were able to save weeks of leadtime and thousands of dollars. Once the new pitch was established, the design was sent off to a tool shop to be machined from aluminum.
