Additive Manufacturing of Advanced Ceramics Using Preceramic Polymers

Abstract

Ceramic materials are used in various industrial applications, as they possess exceptional physical, chemical, thermal, mechanical, electrical, magnetic, and optical properties. Ceramic structural components, especially those with highly complex structures and shapes, are difficult to fabricate with conventional methods, such as sintering and hot isostatic pressing (HIP). The use of preceramic polymers has many advantages, such as excellent processibility, easy shape change, and tailorable composition for fabricating high-performance ceramic components. Additive manufacturing (AM) is an evolving manufacturing technique that can be used to construct complex and intricate structural components. Integrating polymer-derived ceramics and AM techniques has drawn significant attention, as it overcomes the limitations and challenges of conventional fabrication approaches. This review discusses the current research that used AM technologies to fabricate ceramic articles from preceramic feedstock materials, and it demonstrates that AM processes are effective and versatile approaches for fabricating ceramic components. The future of producing ceramics using preceramic feedstock materials for AM processes is also discussed at the end.

Development of Inkjet Printable Formulations Based on Polyorganosilazane and Divinylbenzene

“…Many applications can already be found in areas such as medical devices [12,13], automotives [14,15], and aerospace [16,17]. 3D printing techniques such as vat photopolymerization, which includes digital light processing [18][19][20][21] and stereolithography [22,23], fused deposition modeling [24,25], direct ink writing [26,27], and inkjet printing [28], are already being applied on advanced ceramic materials such as preceramic polymers [29,30]. The technique being used in this work is inkjet printing.…”
