| Abstract Scope |
Ceramic stereolithography involves the selective photopolymerization of a ceramic-loaded suspension and is one of the most precise methods of ceramic additive manufacturing. The study aims to develop a nanoscale ZrO2 suspension for high-performance ceramics via stereolithography, addressing challenges in rheology, dispersion, radiation/matter interaction, and printing parameters.
The ceramic suspension is based on TZ-3YS-E zirconia powder (90nm) and acrylate monomers HDDA and TMPTA. The formulation also includes a photoinitiator (TPO) and a dispersant (Disperbyk-103) to achieve low viscosity and avoid sedimentation. The process involves precise weighing, mixing, and ball milling to ensure homogeneity and optimal viscosity. Rheological properties and stability are evaluated concerning dispersant concentration and milling time.
The printing conditons investigates the relationship between laser power, exposure time, and layer formation to optimize polymerization depth and resolution. Results highlight the critical role of these parameters for high-resolution printing, offering insights into formulating compatible nanoscale ceramic suspensions for stereolithography. |
