The ability of Fused Deposition Modeling (FDM) 3D Printing technology to create complex objects makes this technology increasingly widely used. Apart from the advantages of FDM technology, the low dimensional accuracy and mechanical properties of FDM printed parts are one of the drawbacks of this process. In addition, developments in the use of elastic materials to create flexible products make the process of this technology requires special attention. This study focused on knowing the effect of process parameters, namely temperature and build orientation on dimensional accuracy and the value of hardness (Shore D Hardness) of the Thermoplastic Elastomer (TPE) material produced by FDM 3D Printing. The hardness test method refers to the ASTM D2240 standard for measuring Shore D hardness, while the dimensional accuracy is measured using a vernier caliper. The results showed that the temperature and build orientation had an influence on the accuracy and hardness values. The properties of TPE have different results from PLA which is completely shrunk. However, the porosity value does not have a significant effect on hardness, but the number of layers. The research results have been presented both in tables and graphically, and are briefly discussed in this study.
