The buttons on this reference design were designed with the same parameters but due to mechanical tolerances there can be slight differences in performance. Since the design is meant to be 3D printed, different printers or printing technologies have different accuracies and tolerances. Additionally, if a different material is used for the 3D printing, then deflection of the button surface changes and can require more force for a press event to trigger a button output. Even though the buttons on a single print all have the same printer and material, there can still be variation in force required for a button, especially if the design is hand assembled. The tape used to keep the mechanical tolerance can have an impact on the button if it is not uniform or differs between units. To showcase this, an analog force gauge is used to apply a force to the button surface. The force required for each button threshold to trigger is then recorded as well as the raw data response for varying forces. Additionally, testing is performed on two different material types with different 3D printing processes while keeping the same mechanical design.
