Custom Fabrication of Hard Tissue Reconstructive Frameworks
The feasibility of fabricating custom frameworks for tissue regeneration utilizing three-dimensional inkjet printing technology followed by slip casting was investigated. A CAD solid model of mold was created with structures within the mold cavity to provide variable, customized porosity in the cast framework. The polymer mold was printed using a 3D ink-jet printer. The mold was then infiltrated by an aqueous suspension of hydroxyapatite to produce porous frameworks that were tested for mechanical properties.
