Selective Laser Sintering of 13-93 Bioactive Glass
نویسندگان
چکیده
Bioactive glasses are more promising than biopolymers in fabricating scaffolds for bone tissue repair because they convert to hydroxyapatite, when implanted in vivo. Both direct and indirect selective laser sintering (SLS) methods of 13-93 bioactive glass were considered in this research to study the feasibility of fabricating scaffolds for bone repair applications. Stearic acid was used as the binder in the indirect method to fabricate the scaffolds. The green scaffolds underwent binder burnout and sintering at various soaking conditions between 675 0 C and 700 0 C, achieving a maximum compressive strength of 23.6 MPa, which is higher than that of the human cancellous bone. The sintered scaffolds had a pore size varying between 300 μm and 800 μm with 50% apparent porosity.
