Research Paper: Controlling the microstructure of bioceramic scaffolds using 3DP emulsion inks

• Share article :

A research team comprising Liu Quyang , Li Tian, Dr Zhai Wei and AM.NUS researchers Gan Soo Wah,  Chang Soon Yee and A/Prof Yen Ching-Chiuan released a study that focuses on the development of hierarchical porous hydroxyapatite (hpHA) scaffolds for bone tissue engineering (BTE). The scaffolds are fabricated using 3D printing of emulsion inks, which allows for effective control of microporosity and pore morphology. The scaffolds have high porosity (up to 73.7%) and exhibit improved mechanical properties (compressive strength of 1.41-7.84 MPa and Young’s modulus of 57.3-304 MPa) due to the hierarchical porous structure, while also showing improved cell attachment, spreading, and proliferation.

3D printing of emulsion inks is a promising fabrication strategy for the development of highly porous BTE scaffolds with improved mechanical and biological properties, as exhibited in this paper.
