3D printing enables in-situ fabrication of printed electronics. However, printing substrates may be rough, highly porous, and feature zones with discrete wetting or surface properties. For a given geometry, the modulation of material processes and property parameters to maintain geometry remains a significant challenge.
Therefore, in this work we assess the feasibility of printing on non-ideal surfaces via direct ink writing. Initially, mixture design and sequential learning experiments are used to synthesize and tailor structural and conductive ceramic ink rheology. In order to maintain printing and sensor fidelity, techniques such as surface contouring and laser adjusted feedback are assessed to modulate the nozzle height and printing parameters in real-time. Using the inks, thermistors and strain sensors are deposited on curved and macroporous surfaces. Profilometry and microscopy are used to characterize the deposited geometries and assess system functionality. Ultimately, sensor performance is studied as a function of the processing-properties relationships.
