摘要：

In this paper the research focused on the viability of using the selective laser sintering (SLS) technique for creating tissue engineer (TE) scaffolds. A biocomposite blend comprising polylactic acid (PLA) and hydroxyapatite (HA) was used in the research to study the feasibility of the blend to develop scaffolds. The biocomposite blends obtained via physical blending were subjected to laser sintering to fabricate test specimens. The test specimens were characterized using scanning electron microscopy (SEM) and the components before sintering and after sintering were analyzed by infrared spectrophotometry (IR). The results obtained ascertained that SLS-fabricated scaffolds have good potential for TE applications
