Solid free-form techniques for making medical devices for implantation and growth of cells from polymers or polymer/inorganic composites using computer aided design are described. Examples of SFF methods include stereo-lithography (SLA), selective laser sintering (SLS), ballistic particle manufacturing (BPM), fusion deposition modeling (FDM), and three dimensional printing (3DP). The devices can incorporate inorganic particles to improve the strength of the walls forming the pores within the matrix and to provide a source of mineral for the regenerating tissue. The devices can contain tissue adhesion peptides, or can be coated with materials which reduce tissue adhesion. The macrostructure and porosity of the device can be manipulated by controlling printing parameters. Most importantly, these features can be designed and tailored using computer assisted design (CAD) for individual patients to optimize therapy.
A method for making devices for tissue regeneration comprising forming a polymeric matrix using a solid free-form fabrication method to form sequential layers of a biocompatible polymeric matrix having interconnected pores extending throughout the matrix.
