Mechanical Properties of Polyamide Material Using Fused Deposition Modeling Method

Fused Deposition Modeling (FDM) is a popular 3D printing technique that uses thermoplastic polymer materials to produce various objects with high efficiency. The quality of 3D printing in additive manufacturing is affected by several parameters that require adjustment to achieve optimal results, including printing temperature and print height. However, polyamide materials printed using the FDM method often have defects that affect the printing accuracy and mechanical properties of the printed product. The influence of print orientation (0°, 45°, 90°) polyamide printed using FDM technique is seen to be able to overcome this problem. Therefore, the bending test at 0° orientation recorded the highest values compared to orientations at 45° (9 %) and 90° (211 %). In addition, the shear test for the 0° orientation showed the highest shear strength of 17.57 MPa over the 45° and 90° orientation by 1.2 and 2.5 times. The same situation was shown by the tensile test, when the ultimate tensile strength was higher (24.53 MPa) and the strain increased significantly at break (319 %) for the 0° orientation seam while, the compression test recorded a value of 29 MPa. It can be concluded that at the orientation of 0° the performance of the mechanical properties is excellent compared to the orientation at 45° and 90°.
