Abstract Hydroxyapatite (HA) bioceramic scaffolds were fabricated by using digital light processing (DLP) based additive manufacturing. Key issues on the HA scaffolds, including dispersion, DLP fabrication, sintering, mechanical properties, and biocompatibility discussed in detail. Firstly, effects of dispersant dosage, solid loading, sintering temperature studied. The optimal 2 wt%, 50 vol%, 1250 °C, respectively. Then, properties investigated. DLP-prepared porous scaffold was found to...
Cellular ceramic structures (CCSs) have promising application perspectives in various fields. Recently, additive manufacturing (AM), usually known as three-dimensional printing (3D printing), has been increasingly adopted to produce CCSs. Usually, the structural properties of additively manufactured cellular (AM-CCSs), i.e., lightweight characteristics, load-bearing capacity, toughness, unconventional properties, are traditionally investigated. Interestingly, AM technologies a significant...
