Influence of core‐shell structure on the cure depth in photopolymerizable alumina dispersion

Anna Więcław-Midor , Paweł Falkowski , Mikołaj Szafran


The heterogeneous nucleation‐and‐growth processing was used to obtain core‐shell particles based on alpha alumina core with silica layer. Presence of silica shell was confirmed by transmission electron microscopy (TEM) and zeta potential measurement. The coverage of aluminum oxide surface by SiO2 improved a cure of the depth of photopolymerizable ceramic dispersion around 20%. The proposed surface modification enables the production of thicker cured layer which is favorable for additive manufacturing methods such as stereolithography. Thus, the number of layers that have to be printed to form the 3D object might significantly decrease, thereby reducing time and costs of fabrication.
