영어 초록
Recently, it has been applied and used in various fields using 3D printing. Since it is closely connected to our lives, the mechanical properties of the output are actively studied. Therefore, in this study, tensile specimens were manufactured using the FDM lamination method using PLA materials, and the changes in tensile properties were compared and evaluated. First, 120 tensile specimens were manufactured using the spacing angle and lamination density of the lamination angle as control factors. After that, a tensile test was conducted at the same tensile speed of 5mm/s to compare and evaluate the tensile strength and elastic modulus. As a result, it was found that the tensile strength and elastic modulus increased linearly with density than the lamination angle. In addition, when the laminating angle was 0°, the tensile strength and elastic modulus were the largest. When the laminating angle was 108°, the lowest tensile strength and elastic modulus were confirmed.
