A review on the potential of polylactic acid based thermoplastic elastomer as filament material for fused deposition modelling

Currently, a range of sectors are implementing three-dimensional (3D) printing, which is part additive manufacturing (AM) technology via the fused deposition modelling (FDM) approach. As now, various filament materials available in market and have their limitations. Thermoplastic elastomer (TPE) blend as material 3D printing should be implemented to overcome weakness filaments. TPE stands out due its flexibility, thermoplastic-like processability, renewability. Based on findings, can made with polylactic acid (PLA) thermoplastic elastomers such natural rubber (NR) epoxidized (ENR). The printed components will flexible; tough excellent thermal mechanical properties. In this paper, characteristics being reviewed show potential filament.
