“…Table 1 compares the density, dielectric constant, piezoelectric constant and loss tangent of our 3D-printed BaTiO 3 with the typical BaTiO 3 and the BaTiO 3 that is fabricated by other additive manufacturing fabrication methods. [34][35][36][37] Density measured by ASTM B962-14 standard of 3D-printed BaTiO 3 is 5.64 g/cm 3 , which corresponds to 93.7% of the density of bulk BaTiO 3 (6.02 g/cm 3 ). For typical BaTiO 3 , the dielectric loss (tanδ) is usually less than 0.1 and the remnant polarizations Pr is larger than 2μC/cm 2 .…”

Piezoelectric ceramics are currently of considerable interest for their capabilities of converting compressive/tensile stresses to an electric charge, or vice versa. Because ceramics cannot be cast and machined easily, additive manufacturing (AM) processes (3D printing technology) open an effective pathway in geometrical flexibility. However, the piezoelectric properties limit the application of printed ceramics. This work demonstrates that a piezoelectric-composite slurry with BaTiO 3 nanoparticles (100nm) can be 3D printed using Mask-Image-Projection-based Stereolithography (MIP-SL) technology. After a post-process, the density of 5.64g/cm 3 was obtained, which corresponds to 93.7% of the density of bulk BaTiO 3 (6.02 g/cm 3 ). The printed 1 Zeyu Chen and Xuan Song contribute equally to this paper 2 ceramic exhibits a piezoelectric constant and relative permittivity of 160 pCN -1 and 1350respectively. An ultrasonic transducer with printing focused piezoelectric element was fabricated to realize the energy focusing and ultrasonic sensing. A 6.28MHz ultrasonic scan was achieved by the transducer and successfully visualized the structure of a porcine eyeball.

“…The 3D printed piezoceramics must still be activated, but this could be done following the principle outlined in [6]. Moreover, BTO is biocompatible [2,3,5], and can serve as a scaffold material that can be activated by electrical fields in order to stimulate osteoblasts proliferation and differentiation of osteoclasts.…”

“…This is where additive manufacturing comes into play. There have already been investigations regarding the fabrication of BaTiO 3 (BTO) via additive manufacturing [6][7][8], which are addressed in these studies. Besides the production via stereolithography processes, the direct fabrication via 3D printing (3DP) is described.…”

“…Here, the particle size and shape play an important role [9,10]. Untreated BTO powder is mostly a non-flowable material with a mean grain size of a few microns, so that a preparation of the material (in the form of heat treatment) or an addition of flow additives is necessary [6,11]. Therefore, this study uses a calcined BTO on the one hand and on the other hand an untreated BTO is used to which flow additives are added in order to remove powder agglomerations and increase the flowability.…”

Abstract:The present work deals with the 3D printing of porous barium titanate ceramics. Barium titanate is a biocompatible material with piezoelectric properties. Due to insufficient flowability of the starting material for 3D printing, the barium titanate raw material has been modified in three different ways. Firstly, barium titanate powder has been calcined. Secondly, flow additives have been added to the powder. And thirdly, flow additives have been added to the calcined powder. Finally, a polymer has been added to the three materials and specimens have been printed from these three material mixtures. The 3D printed parts were then sintered at 1320°C. The sintering leads to shrinkage which differs between 29.51-71.53% for the tested material mixtures. The porosity of the parts is beneficial for cell growth which is relevant for future medical applications. The results reported in this study demonstrate the possibility to fabricate porous piezoelectric barium titanate parts with a 3D printer that can be used for medical applications. 3D printed porous barium titanate ceramics can especially be used as scaffold for bone tissue engineering, where the bone formation can be promoted by electrical stimulation.

“…The effect of layer thickness was not investigated due to the existence of previous works. [25][26][27][28][29] The results of this study can be used as a preliminary guideline for adjusting the printing parameters for new material development and the better understanding of the binder jetting processes.…”

Custom ceramic structures possess significant potentials in many applications such as dentistry and aerospace where extreme environments are present. Specifically, highly customized geometries with adequate performance are needed for various dental prostheses applications. This paper demonstrates the development of process and post-process parameters for a dental porcelain ceramic material using binder jetting additive manufacturing (AM). Various process parameters such as binder amount, drying power level, drying time and powder spread speed were studied experimentally for their effect on geometrical and mechanical characteristics of green parts. In addition, the effects of sintering and printing parameters on the qualities of the densified ceramic structures were also investigated experimentally. The results provide insights into the process-property relationships for the binder jetting AM process, and some of the challenges of the process that need to be further characterized for the successful adoption of the binder jetting technology in high quality ceramic fabrications are discussed.
