摘要: Hydroxyapatite suspensions were extruded through a range of nozzles from 100 to 330 μm diameter stepper-driven syringe. Regular latticework scaffolds built by fused deposition modeling (FDM), solid freeforming method, on three-axis table using filament. The sintered at 1250°C 97% density retaining the hydroxyapatite crystal structure. introduced cultured human osteoblast cells and, after 48 h, surfaces thoroughly covered with active cells.
