Antibacterial Silicate Glass-Ceramic Filament for 3D Printing Bone Materials
The use of 3D printed porous scaffolds provides a multi-dimensional template that closely mimics the native structure of bone. This is beneficial for creating ideal conditions for bone tissue regeneration. Silicate bioactive glass-ceramics are inherently bioconductive and bioinductive, making them ideal for tissue regeneration.
DESCRIPTION OF TECHNOLOGY
The inventors have fabricated 3D printed silicate bioactive and antibacterial silver-doped glass-ceramic (Ag-BG) scaffolds using a fused filament fabrication (FFF) additive manufacturing technique. The thermal debinding and sintering processes minimize the structural deformation of the Ag-BG scaffolds and the compressive strength of these Ag-BG scaffolds is in the range of cancellous bone. The inventors have shown that the 3D printed scaffolds also have bioactive behavior and anti-methicillin resistant Staphylococcus aureus (MRSA) activity.
