Abstract

The rapid development of additive manufacturing in last decades has greatly improved the quality of medical implants and widened its applications in tissue engineering. For the purpose of creating realistic porous scaffolds, a series of diverse methodologies are attempted to help simplify the manufacturing process and to improve the scaffold quality. Among these approaches, implicit surface methods based on geometric models have gained much attention for its flexibility to generate porous structures. In this paper, an innovative heterogeneous modeling method using anisotropic radial basis functions (ARBFs) is introduced for designing porous structures with controlled porosity and various internal architectures. By re-defining the distance method for the radial basis functions, the interpolated porous shape can be customized according to different requirements. Numerous experiments have been conducted to show the effectiveness of the proposed method.
