The design of multifunctional materials with controlled micro-features is critical for many applications. To achieve high-resolution 3D printing, melt electrowriting (MEW) emerged as a novel electrohydrodynamic technique that allow to deposit polymeric microfibres in a very precise way. Despite its advantages, MEW is a young technology, so there are plenty of possibilities to be explored. In particular, the use of functional fillers within the MEW-processed structures to promote active properties remains so limited. This work explores the potentials of MEW for active materials printing by using different fillers. In particular, magnetic, conductive and color changing fillers are explored for develop sensors, actuators and conductive samples. Results demonstrate that different complex microstructures, including multi-material, with up to 6% wt. of fillers could be successfully printed without affecting to the printing quality and providing the printed structures with the desired active properties (magnetic response, actuation and/or sensing response).
