“…This shift in absorption wavelength is consistent with the difference in particle size of the two powders, as the nanoparticles of BTO2 shift the light absorption to shorter wavelength [18]. As both BTO powders mainly absorb at a shorter wavelength (higher energy) than the laser wavelength used for printing (405 nm), the absorption of light during printing may not hinder the curing of the resins [19,20].…”

Stereolithography is a layer-by-layer building fabrication technique enabling production of advanced ceramic 3D shapes that are not achievable by other methods. Critical parameters of stereolithography are associated with the preparation of a ceramic resin exhibiting suitable rheological and optical properties, as well as tunable curing property to achieve the desired level of resolution of complex 3D parts. However, tailoring the cure depth for each layer is challenging for functional ceramics due to their high refractive index giving increased light scattering. Here, the stereolithography 3D printing of BaTiO3 ceramic resins is investigated by employing a desktop 3D printer (λ = 405 nm) and a commercial base resin. The effects of two BaTiO3 powders with different size distributions (one micro-sized powder with grains in the range 1–20 µm, and one agglomerated nano-sized powder in the range 60–100 nm), on the viscosity and curing characteristics of the ceramic resins were investigated. It is shown that the nano-sized powder resulted in increased viscosity, increased scattering, and reduced cure depth compared to the micro-sized BaTiO3 ceramic resin. In general, the cure depth decreased with increasing ceramic loading. Successful prints were obtained for an overcuring of at least 40% between layers to assure good adherence between the layers. The printing properties of the ceramic resins from both powders were suitable for printing green parts with 50 µm layer thickness.

The article presents the results of the synthesis of lead-free piezoceramic materials (Ba0.9Ca0.1)(Ti0.9Zr0.1)O3 (BCZT system) in spherical powder form and their subsequent application in the binder jetting additive manufacturing process. Green models were manufactured using this powder material with binder jetting, different sintering modes were investigated, and the functional piezoelectric properties were measured. Lattice structures with triply periodic minimum surface topologies, such as Gyroid and Schwarz, were designed and manufactured. It is shown that the functional properties of lattice structures depend on the parameters of the cells and the chosen topology.

“…Additive manufacturing technology has the advantages of fast molding, high precision, wide material applicability, and direct forming, which can realize the rapid fabrication of devices with complex structures [10]. At present, additive manufacturing technology has been widely applied in the fabrication of ultrasonic phased arrays [11], such as direct ink writing [12,13], digital light processing [14,15], and stereolithography [16,17]. Although these methods solve the shortcomings of traditional manufacturing processes, this onestep process of modeling ceramic bodies makes it no longer applicable to prepare electrodes by magnetron sputtering.…”

The electrode is an important part of a micro-ultrasonic phased array, commonly fabricated by magnetron sputtering technology. However, with the expansion of the application field, the structures of the phased arrays are becoming more complex, making the traditional magnetron sputtering method no longer applicable, and the realization of micro-scale phased array electrodes by direct printing technology still faces great challenges. Herein, an electric field-driven direct printing method was proposed to fabricate micro-ultrasonic phased array electrodes. The influence of sintering parameters on the resistivity and the effect of printing parameters on the geometric size and surface morphology of the electrode were comprehensively explored, and the mathematical model between the electrode line width and the printing parameters was established. The final printed electrodes exhibit superior properties with a resistivity of 2.4×10-7 Ω·m, a surface roughness range of 460-550nm, and a line width range of 125-480µm. Additionally, a micro-scale electrode was printed on the piezoelectric ceramic with PZT-5 as the material, and after polarization treatment, the piezoelectric coefficient can reach 405 pC/N, which proves that this method can be applied in the field of fabricating phased array electrodes.
