Y-TZP, Ce-TZP and as-synthesized Ce-TZP/Al2O3 materials in the development of high loading rate digital light processing formulations

Ceria-stabilized zirconia-based composites printed by stereolithography: Impact of the processing method on the ductile behaviour and its transformation features

“…Indeed, their excellent intrinsic resistance to defects should be able to guarantee the maintenance of mechanical properties even if certain defects are introduced during AM. Despite the limited litterature on ceria-based ceramics processed by photopolymerization AM techniques [17], there is currently no such photopolymerizable slurry/paste commercially available. The present work is conducted with a number of aims in mind.…”

UV‐Curing Assisted Direct Ink Writing of Dense, Crack‐Free, and High‐Performance Zirconia‐Based Composites With Aligned Alumina Platelets

“…In particular, zirconia remains one of the challenging ceramics due to the relatively high refractive index (2.24 at 365 nm). [ 33 ] AM of zirconia ceramics nevertheless has high potential for various structural and functional applications, such as to produce turbine‐blade cores, photonic crystals for advanced millimeter wave applications, fuel cells, dental prostheses, and so on, all involving customized design of complex geometries and combining different materials. [ 34,35 ] In this study, alumina‐toughened zirconia (ATZ), containing 20 wt% alumina (3 wt% platelets and 17 wt% particles) and 0.4 mol% La 2 O 3 ‐doped 2Y‐TZP, was printed.…”

Controlled Desiccation of Preprinted Hydrogel Scaffolds Toward Complex 3D Microarchitectures

“…[11,12] Thus, using synthetic hydrogels as sacrificial templates allows for building micro-objects by volume shrinkage. [13,14] Recent works have focused on light-curing polymer templates, [15,16] while the removal of these templates requires high-temperature treatment [17,18] or toxic solvents. [19,20] Printing high-volume change hydrogel templates with DIW methods for fabricating microstructures is also promising but remains largely unexplored.Here, we report a new AM strategy named "indirect desiccation fabrication (iDF)", which can create complicated 3D microarchitectures at the macroscopic level through controlled desiccation of DIW-printed sacrificial hydrogel scaffolds followed by infilling and solidifying objective inks (Figure 1a).…”
