Abstract Additive manufacturing (AM) has the potential to disrupt the ceramic industry by offering new opportunities to manufacture advanced ceramic components without the need for expensive tooling, thereby reducing production costs and lead times and increasing design freedom. Whilst the development and implementation of AM technologies in the ceramic industry has been slower than in the polymer and metal industries, there is now considerable interest in developing AM processes capable of producing defect-free, fully dense ceramic components. A large variety of AM technologies can be used to shape ceramics, but variable results have been obtained so far. Selecting the correct AM process for a given application not only depends on the requirements in terms of density, surface finish, size and geometrical complexity of the part, but also on the nature of the particular ceramic to be processed. This paper provides a detailed review of the current state-of-the-art in AM of advanced ceramics through a systematic evaluation of the capabilities of each AM technology, with an emphasis on reported results in terms of final density, surface finish and mechanical properties. An in-depth analysis of the opportunities, issues, advantages and limitations arising when processing advanced ceramics with each AM technology is also provided.

先进陶瓷材料的增材制造

摘要 增材制造 (AM) 为制造先进的陶瓷部件提供了新的机会，无需昂贵的工具，从而降低生产成本和交货时间并增加设计自由度，从而有可能颠覆陶瓷行业。虽然陶瓷工业中增材制造技术的开发和实施比聚合物和金属工业慢，但现在人们对开发能够生产无缺陷、完全致密陶瓷部件的增材制造工艺产生了相当大的兴趣。多种增材制造技术可用于塑造陶瓷，但迄今为止获得的结果各不相同。为给定应用选择正确的增材制造工艺不仅取决于零件的密度、表面光洁度、尺寸和几何复杂性方面的要求，但也取决于要加工的特定陶瓷的性质。本文通过系统评估每种增材制造技术的能力，详细回顾了当前先进陶瓷增材制造的最新技术，重点介绍了最终密度、表面光洁度和机械性能方面的报告结果. 还提供了对使用每种 AM 技术加工高级陶瓷时出现的机会、问题、优势和局限性的深入分析。
