The present study aims to investigate the mechanical properties of three-dimensional cellular foam scaffolds for cell culturing. Three-dimensional ordered cellular scaffolds with various relative densities were first manufactured using an approach based on microfluidics. Systematic characterization on the microstructural geometry of the foam scaffold was subsequently performed. Analytical as well as FEM models were then developed based on the geometric features measured. Mechanical parameters such as the elastic modulus, the Poisson’s ratio and the shear modulus were established analytically as well as numerically. Meanwhile, experimental result on the elastic modulus was also obtained by testing a prototype model. Experimental and numerical results agree well to each other which in turn justify the validity of the FEM models.
