Abstract

Although additive manufacturing offers numerous potential advantages for fabricating functional, complex geometry zirconia parts with efficiency, industrial interest in practical applications is currently lacking. This potentially stems from the need for a more comprehensive investigation into the performance of additively manufactured zirconia components, which is essential for promoting and initializing industrial applications. The aim of this study is thus to provide a detailed evaluation of zirconia specimens fabricated by one of the most utilized ceramic additive manufacturing technologies, viz. digital light processing (DLP), with a range of typical zirconia components being printed. Key performance factors captured within include achievable density, surface quality measurements, dimensional accuracy, degree of shrinkage, and mechanical properties. The results of this work demonstrates that the performance of the DLP-prepared zirconia parts is comparable to those of conventionally fabricated zirconia. It is believed that this paper will serve as a good reference for academic and industrial communities interested in this rapidly expanding field.
