Three-dimensional Porous Polylactic Acid Bone Scaffolds: Web Lamination Techniques and Property Evaluations
This study aims at producing three-dimensional porous polylactic acid (PLA) bone scaffolds using a web manufacturing. Webs are laminated and are then processed with heat treatment in order to form low *melting point PLA porous bone scaffolds. A stereomicroscope, a scanning electron microscope, the pore size measurement, porosity, and compression test are used in order to evaluate the bone scaffolds. The test results indicate that regardless of the temperatures of heat treatment, all PLA porous bone scaffolds have interconnected pores. An increasing temperature of treatment causes the pore size to decrease from 160μm to 100μm and mechanically improves the bond scaffolds. Therefore, this study successfully creates porous bone scaffolds made of low melting point point PLA and web lamination techniques.
