• The development of a 3D printed force sensor for a gripper was studied applying an embedded constantan wire as sensing element. In the first section, the state of the art is explained. In the main section of the paper the modeling, simulation and verification of a sensor element are described for a three-point bending test made in accordance with the DIN EN ISO 178.

In the first section, the state of the art is explained. In the main section of the paper the modeling, simulation and verification of a sensor element are described for a three-point bending test made in accordance with the DIN EN ISO 178. The 3D printing process of the Fused Filament Fabrication (FFF) utilized for manufacturing the sensor samples in combination with an industrial robot are shown. A comparison between theory and practice are considered in detail. Finally, an outlook is given regarding the integration of the sensor element in gripper jaws.…
