Selective Laser Sintering of Biopolymers with Micro and Nano Ceramic Additives for Medicine

Biocompatible oxide ceramics were added to bioresorbable polymeric powders for the laser-assisted fabrication of the porous tissue engineering scaffolds. The optimal regimes were determined for the Nd+3 YAG laser sintering. Microstructure researches of the sintered samples were carried out by means of the SEM equipped the EDX and the results were compared with those of the X-ray analysis. The observations showed that after a successful laser sintering the increase of the nano ceramic particles sizes was insignificantly. The results confirm the medical resource of the SLS-fabricated tissue engineering scaffolds.
