During printing, the sensor layer is applied to those parts of the component that will be subjected to load. When in use, the electrical resistance of the sensor material is measured continually so that a warning is issued before overloading or before the wear limit is reached.
Based on the procedure for multi-material printing, wear-resistant parts with integrated sensor layers are developed. The components are made from the wear-resistant filaments iglidur i150
or iglidur i180
and a specifically developed electrically conductive 3D printing material that sticks well to the tribofilament. Currently, there are two application areas:► Warning before overload occurs:
The electrically conductive material is situated between the wearing layers. If the load changes, the resistance also changes. To determine the load limits, the bearing has to be calibrated correspondingly. ► Reaching of the wear limit:
the conducting path is located in the gliding surface, the wear is measured via the der change of the resistance. Become a beta tester and try 3D isense for free: we are offering ten selected customers the opportunity of free samples with intelligent special parts.
