"Stabilization of tricalcium phosphate slurries against sedimentation for stereolithographic additive manufacturing and influence on the final mechanical properties";
International Journal of Applied Ceramic Technology,
Ceramic parts manufactured by Lithography-based Ceramic Manufacturing (LCM) excel in resolution and surface quality. The material for LCM is a photosensitive ceramic particle-filled slurry which needs to have homogeneous properties over time and during each processing step.
The goal of this study was to use `mechanical´ stabilization for a TCP-filled slurry done by increasing slurry viscosity, solids loading or inducing thixotropic behaviour. The modified slurries were compared with a non-stable reference slurry.
While all methods lead to increased storage stability only the stabilized slurry with 0.5 wt% f SiO2 is stable during the printing process.
