Three-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.

In this study, the effect of the direction of the printing and annealing process on mechanical
properties of 3D printed PLA samples were investigated based on fatigue performance. The tensile-
fatigue properties of the tensile specimen which is produced from PLA by 3D printing in the face-up
(X), edge-up (Y) and up-right (Z) direction were investigated in three different orientations. The
elastic modulus was highest in the Y orientation and lowest in the Z orientation. In addition, the
effect of annealing process on mechanical properties was investigated by applying annealing at 50
°C, 70 °C, 90 °C to the samples printed in the same direction (face-up). Mechanical properties
increased with heat treatment. Mechanical strength was highest at 90 °C.
