Abstract:

We present a 15 N nominal force sensor, manufactured with a disruptive method based on laser-based powder-bed-fusion. This additive manufacturing process enables the application-specific realization of a deformation element for a structural integrated sensor for condition monitoring applications. Manufacturing of the deformation element is done by interupting the laser-based powder-bed-fusion process after printing a base body, i.e. to insert a steel plate as a measuring element carrier. The process is then continued to create a firmly bonded material connection. In order to investigate the strain transmission from the printed part to the integrated steel plate, we built prototypes with different geometries. Our prototypes feature small linearity and hysteresis error of 0.05 % full scale and 0.1 % full scale, respectively. Thus, a robust strain transmission from the printed part to the integrated steel plate and the suitability of the laser-based powder-bed-fusion process for additive manufactured force sensors are confirmed.
