Functional additive fabrication of simple sensor systems
The additive fabrication of objects with electrical or magnetic functionality is still a challenge especially for smaller dimensions. We combine different 3D and screen printing techniques to showcase the possibilities of simply printing custom sensor elements and ‘smart’ parts.
While additive manufacturing is revolutionizing product developments in many fields, in this project we are investigating simple methods to take advantage of this rapid progress for sensor systems and smart materials. In our case we use 3D printing primarily to build application specific part geometries and combine different techniques to integrate electrical, magnetic or elastic functionality. For example, many layer-by-layer processes are limited to a single material per part. Here, the added functionality can be embedded during or after the printing process using screen printing of functional elements on thin foils or directly on the 3D object. This allows simple, rapid, and low-cost production of small batches of custom parts for measuring, e. g., forces, acceleration, pressure or temperature.
