Abstract
A method of fabricating a scaffold for tissue engineering that includes a frame structure including one of poly-D-lactic acid and poly-L-lactic acid and a coating layer formed on a surface of the frame structure and including a lactic acid-glycolic acid copolymer. The method includes mixing a first granular porous substance including one of poly-D-lactic acid and poly-L-lactic acid with a second granular porous substance including the lactic acid-glycolic acid copolymer to prepare a mixture, and pressurizing and heating the mixture in a mold. In the heating, the mixture is heated to a temperature greater than or equal to the melting point of the lactic acid-glycolic acid copolymer and less than the melting point of one of poly-D-lactic acid and poly-L-lactic acid.
