AbstractThree-dimension(3D) printer using Fused Deposition Modeling (FDM) can be efficiently and quickly produced scaffold for the treatment of bone defects or injury. We carried out that bio-composite material(CaSO4/PLA) like natural bone substitute was obtained via extruder and biocomposite material filament in the ratio of 10:90 was produced to be suitable 3D-printer. Also, this work focused design of the 3D bone structure to print by using poly (lactic acid) (PLA) filament consist of about %10 Calcium Sulfate. The obtained bio-composite filament was characterized by thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC). Therefore, CaSO4/PLA scaffolds fabricated via FDM 3D-printer by using a filament.
