“…Direct ink writing (DIW) that consists of a moving nozzle dispensing ink onto a substrate has been utilized in lead‐based piezoelectric ceramics such as Pb(Zr,Ti)O 3 (PZT) and (Pb,La)(Zr,Ti)O 3 . But for the lead‐free piezoelectric ceramics, most reports are related to the FDM from a composite filament of lead‐free piezoelectric powders embedded in a plastic matrix . Moreover, printing via DIW an aqueous lead‐free ink is seldom reported.…”

Direct ink writing (DIW) has become a widespread additive manufacturing technique for material engineering, but its application in lead‐free Ba0.85Ca0.15Zr0.1Ti0.9O3 piezoelectric ceramics from aqueous systems has not been reported so far to our knowledge. The main obstacle is the high extent of hydrolysis reactions undergone by the starting powders when dispersed in water, hindering the attainment of stable water‐based colloidal suspensions. This paper reports on the preparation of stable aqueous inks from a deagglomerated and surface‐treated powder synthesized by solid‐state reaction and on DIW of macroporous lead‐free piezoelectrics. Based on zeta potential and rheological measurements, the optimal amounts of processing additives (dispersant, binder, and coagulating agent) were selected to transform the initial fluid suspension to a viscoelastic paste with sufficient stiffness and stability for the printing process. Dielectric and piezoelectric properties of samples sintered under different temperatures were also investigated.

“…PZT samples were debinded at 500 • C for 2 h followed by sintering at 1200 • C for 2 h (Pyrotec PY12H, Pyrotec GmbH, Osanbrück, Germany) whereas BT samples were debinded at 500 • C for 2 h and sintered at 1350 • C for 5 h (Nabertherm LHT 04/17, Nabertherm, Lilienthal, Germany). For the debinding process, a heating rate of 3 • C/min until 200 • C followed by 0.25 • C/min until 500 • C was used to allow slow decomposition of thermoplastic binder, present in the samples [28]. To prevent lead volatilization, a lead-rich atmosphere was created inside the sealed crucible by coating it with 0.92 g lead-(II)-zirconate powder (Sigma-Aldrich, Buchs, Switzerland) and 0.08 g zirconia (ITN NANOVATION GmbH, Saarbrücken, Germany), per sample [11].…”

Piezoelectric composites with 3-3 connectivity gathered attraction due to their potential application as an acoustic transducer in medical imaging, non-destructive testing, etc. In this contribution, piezoelectric composites were fabricated with a material extrusion-based additive manufacturing process (MEX), also well-known under the names fused deposition modeling (FDM), fused filament fabrication (FFF) or fused deposition ceramics (FDC). Thermoplastic filaments were used to achieve open and offset printed piezoelectric scaffold structures. Both scaffold structures were printed, debinded and sintered successfully using commercial PZT and BaTiO3 powder. For the first time, it could be demonstrated, that using the MEX processing method, closed pore ferroelectric structure can be achieved without pore-former additive. After ceramic processing, the PZT scaffold structures were impregnated with epoxy resin to convert them into composites with 3-3 connectivity. A series of composites with varying ceramic content were achieved by changing the infill parameter during the 3D printing process systematically, and their electromechanical properties were investigated using the electromechanical aix PES device. Also, the Figure of merit (FOM) of these composites was calculated to assess the potential of this material as a candidate for transducer applications. A maximum for the FOM at 25 vol.% of PZT could be observed in this study.

“…For example, to produce more complex ceramic tetrahedral structures, fused deposition of ceramics (FDC), an FDM technology, uses thermoplastic filaments to manufacture intricate structures. Bach et al applied FDC technology to manufacture grid structures (figure 2(b)) to obtain high-performance and functional piezoelectric ceramic structures [49]. High-load ceramic-EVA (vinyl ethyl acetate) was used as the raw material to combine with PZT powder.…”

Three-dimensional (3D) printing technology has attracted significant attention for fabricating piezoelectric materials due to its high efficiency and capability to produce complex structures. Motivated by the desire to address limitations in conventional methods for fabricating piezoelectric materials, this review first introduces commonly used 3D-printing technologies to fabricate piezoelectric materials. The advantages of the technologies are evaluated. Subsequently, typical piezoelectric materials produced by 3D-printing methods are specifically discussed. The properties of the printed materials, such as dielectric and piezoelectric properties, are presented. Significant applications of 3D-printed piezoelectric materials are further explored, highlighting the potential of fabricating 3D-printed piezoelectric materials for biomedical applications. Finally, future directions and opportunities for 3D-printed piezoelectric materials are highlighted.
