Abstract

Scaffold architecture such as pore geometries, porosity and pore size have great effect in tissue engineering in term of mechanical and biological properties. Although 3D-printing has been used in making a porous scaffold, however there are still challenges in designing the geometries in mimicking bone architecture as well as bone properties. A scaffold with hexagon pattern pores and microchannel has been designed and Acrylonitrile Butadiene Styrene (ABS) has been used as the fabricating materials by using a 3D-printer. The 3D-printed scaffold was then observed under an inverted fluorescent microscope to observe the scaffold pores to make comparison with the original pore shape of designed scaffold. The printed scaffold only has 23% to 26% of the original pore size might e due to the material selection as well as the chosen temperature in printing process.
