Abstract

3D printing technique can be used to fabricating complex-structure ceramics, but the internal microstructure and properties along vertical and horizontal directions may show certain anisotropy due to the layer-by-layer process. This work aims to evaluate 3D printing anisotropy quantitatively for performance optimization via the stereolithography method. The square-shaped barium titanate (BTO) ceramics with three different solid contents (75 %, 80 % and 85 %) were prepared to characterize the differences between the vertical and horizontal directions of the ceramics, including microstructure, phase structure, electrical properties and mechanical properties. The electrical and mechanical performances of the printed BTO ceramics in vertical direction are superior to that of horizontal direction, and the differences firstly decrease with the solid contents increasing to 80 % and then increase slightly with further solid content increasing. Besides, the printed BTO ceramic with 80 wt% solid content has excellent electrical performance. This study may provide a potential way for achieving high performance and low anisotropy in the vertical and horizontal of printed ceramics.

固体含量对 3D 打印钛酸钡压电陶瓷各向异性的影响

三维打印技术可用于制造复杂结构的陶瓷，但由于逐层打印的过程，陶瓷内部的微观结构和性能在垂直和水平方向上可能会表现出一定的各向异性。本研究旨在通过立体光刻法对 3D 打印各向异性进行定量评估，以优化性能。制备了三种不同固含量（75%、80% 和 85%）的方形钛酸钡（BTO）陶瓷，以表征陶瓷垂直和水平方向的差异，包括微观结构、相结构、电气性能和机械性能。垂直方向上的印刷 BTO 陶瓷的电气性能和机械性能均优于水平方向上的印刷 BTO 陶瓷，而且随着固含量增加到 80%，差异首先减小，然后随着固含量的进一步增加而略有增大。此外，固含量为 80% 的印刷 BTO 陶瓷具有优异的电气性能。这项研究为实现印刷陶瓷在垂直和水平方向上的高性能和低各向异性提供了一种可能的方法。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
