Pure β-TCP scaffolds with an aligned, lamellar, open and interconnected porosity were fabricated by the ice-templating process. The morphology of the scaffold was analysed and the mechanical properties of the different scaffolds were tested by compression tests. The structural sizes of the scaffolds (pore width and ceramic cell wall thickness) were adjusted by the onset of a constant ice front velocity. For this purpose a freezing device was developed and a specific solution of the non-steady heat equation with a disturbing factor (phase transformation energy from water) was used to model the process parameters. It was found that increasing the ice front velocity decreases the structural sizes and consequently increases the compression strength of the scaffold.
