The objective of this thesis is to design and create a joystick, based on the force sensing units using multi-material Fused Deposition Modelling (FFF/FDM). The thesis covers the process and parameters involved in designing and producing a resistive force sensor, focusing on considerations for integrating flexible conductive TPU and PLA materials into a functional component. Data collection is carried out using a testing machine, and an analysis of the sensor's signal during loading and unloading cycles is performed to characterize its response. Additionally, the project encompasses design iterations, an economic assessment of the proposed solutions, and a sustainability analysis of the outcomes.
