Abstract:
1. An apparatus for use in tissue engineering, wherein said apparatus comprises a scaffold, said scaffold structure comprising: a plurality of horizontal layers of scaffold material, wherein each horizontal layer is sequentially adhered to the adjacent layer, wherein each horizontal layer comprises a plurality of raster roads of melt extrusion filament material selected from polycaprolactone (PCL), a polycaprolactone/hydroxyapatite (PCL/HA) composite, or a polycaprolactone/tricalcium phosphate (PCL/TCP) composite with a fill gap between each raster road, thereby providing a horizontal channel between each raster road, wherein the ratio of the raster road width to the channel width is constant in each layer, wherein the each sequential layer is deposited at different raster angles in the z-axis view, and wherein deposition of sequential layers at different raster angles produces a consistent pore size in the scaffold, thereby providing a scaffold structure having interconnected channels, said scaffold structure is a scaffold for use in tissue engineering.
