Gradually Porous Ceramic Scaffolds using Ceramic/Camphene-based Three-Dimensional Co-Extrusion |
| 초록 |
Porous calcium phosphate(CaP) bio ceramics have received much interest as bone graft replacements primarily due to their ability to lead efficient bone ingrowth and vascularization of afresh tissue and simultaneously it have been used bone scaffolds and porous piezoelectric. We herein demonstrate a novel, versatile approach to produce biomimetic porous ceramics with a continuously gradient porous structure using three-dimensional extrusion of a bilayered ceramic-camphene mixture/pure camphene feedrod. In this study, bi-layered feed rod comprised of the ceramic/camphene mixtures and law contents of ceramic or pure camphene used as the lower and upper part feed rod. Bi-layered feed rod could be gradually extruded with core/shell structure because of the wall slip phenomenon. This enabled the formation of green filaments comprised of a camphene core surrounded by a ceramic/camphene shell, where the core/shell thickness ratio increased gradually as extrusion proceeded. Biphasic calcium phosphate (BCP) ceramics with a gradient porous structure could be successfully produced by three-dimensionally depositing the extruded filaments layer by-layer. We evaluated gradient micro structure with produced gradient porous BCP ceramic scaffold by scanning electron microscopy (SEM) and Micro CT. |
