The process conditions used in the scaffold preparation resulted in microstructures with a high sintering degree. The range of porosity values obtained for the scaffolds was 26–30%, which is appro- priate for scaffold applications, and the average pore size in the PLDLA/BG scaf- folds was 200 lm. The flexural modulus, ultimate strength, and elongation values for the PLDLA/BG scaffold specimens decreased for scaffolds with 20 and 30% of BG, probably due to the low chemical affinity between the polymeric and the ceramic phase. The PLDLA/BG scaffolds exhibited flexural modulus values between 10 and 79 MPa, depending on the scaffold composition, which lie within the range reported for human bone. In the direct cytotoxicity tests, cells seeded on PLDLA/BG scaffolds showed a high viability, indicating that the PLDLA/BG scaffolds prepared by selective laser sintering can be applied in bone repair.
