“…Inkjet printing involves ejecting materials as a specific liquid or ink through the nozzle of the printer, and the ejected droplets are deposited and then cured by UV light or by using in situ chemical reactions to build the object [ 30 , 31 ]. This 3D printing technique can be performed at low temperatures and pressures, uses a wide range of materials, and prints in a time almost independent of the complexity of the product, but printing complex 3D products and hollow structure objects is still limited [ 32 ].…”

“…Whereas the operational variables can be easily set, the control of those related to the ink can be especially challenging when using thermocurable or reactive inks. [51,52] In this regard, MREs composed of, for example, soft PDMS-based matrices filled with magnetic particles, are very convenient for applications where soft biological tissue-like multifunctional materials are needed. [9,17,53] These materials are initially in a fluid-phase state that evolves with time during curing to a solid state.…”

Soft multifunctional materials allow for mechanical sensing or actuation as a response to multiple physical stimuli, while providing material stiffness that mimic soft biological tissues (≈1–10 kPa). One of the main bottlenecks in the state of the art relates to the difficulty for manufacturing complex shapes when using inks whose properties significantly change over the printing time. To overcome this issue, the implementation of a hybrid (theoretical‐experimental) framework that allows optimal printability of time‐dependent viscosity inks by using the direct ink writing technology. Although the rheological properties of the ink vary during printing time, a combination of theoretical and experimental methods provides evolving printing conditions that ensure efficient and robust printability over the process. The method removes the need of introducing additives to the ink. To enable this technology, an in‐house printer that provides flexibility to modulate the extrusion pressure over printing time is developed. The method is validated by manufacturing magnetorheological elastomers and conductive soft materials for specific bioengineering and soft electronics applications.
