Currently material extrusion 3D printing (ME3DP) based on fused deposition (FDM) is considered a highly flexible and efficient additive manufacturing technique. This sophisticated technique has promise to develop components with complex geometries using computer-assisted design. While the 3D printing process for a number of thermoplastic materials using FDM technology has been well demonstrated, there still exists a significant challenge to develop compatible ME3DP and new polymeric materials. Thus far, there are very limited studies done on this subject. The present research would discuss the developments of thermoplastic elastomers from Polypropylene (PP) and styrene ethylene butadiene styrene (SEBS) rubber with tailor physico-mechanical properties for ME3DP. Reinforcing carbon black was used to improve mechanical and dynamic mechanical performance of 3D-printed TPEs. Finally properties of 3D printed sample were compared with traditional injection molded sample. Printed process parameters-structure-property relationship of this TPE will be presented.
