Effects of zinc silicate additive on the physicochemical properties and cellular behaviors of 3D-printed magnesium phosphate bioceramic scaffolds.

Magnesium phosphate (MP) is a promising bone regeneration material, but it lacks the capacity to efficiently stimulate osteogenesis. In this work, zinc silicate (ZS) was used as an additive to modify MP bioceramics, and the MP-ZS composite bioceramic scaffolds with three-dimensional macroporous structure were fabricated by fiber deposition-based 3D printing and subsequent high-temperature sintering. New silicate phase was produced during sintering the MP-ZS bioceramic scaffolds.
