Fabrication of macroporous hydroxyapatite[HA] scaffolds comprised of microporous hollow filaments by Photocuring–assisted 3D plotting technique using core-shelled feedrod consisting of microporous HA shell and Carbon black[CB] core |
| 초록 |
This study demonstrates the macroporous hydroxyapatite (HA) scaffolds, comprised of microporous hollow filaments with high shape retention, by photocuring-assisted 3D plotting using a feedrod comprised of a photocurable HA shell and a carbon black (CB) core. The 3D porous HA scaffold was produced using photocuring assisted 3D plotting, and these heat-treated scaffolds have pores consisting of micropores by camphene/camphor crystal, macropores by CB core and filament gap. The porosity was controlled by camphene/camphor vol.% [50 and 60vol.%] and different filament gaps [1.0 and 0.5 mm]. The 4 types of sintered scaffolds have overall porosity of 74.3 ~ 79.3 % and 50.7~64.6 % respectively. The mechanical properties of two types of scaffolds with porosity of 74.3 ~ 79.3 % were exhibited reasonably high compressive strengths (2.36 ― 3.58 MPa) and modulus (68–86 MPa). The various ceramic architecture and ceramic scaffold without supporter were produced by photocuring-assisted 3D plotting. |
