Abstract

Additive manufacturing (AM) is a well-known method of 3D printers. The AM method forms components by laminating thin layers. Therefore, this method can make prototypes of parts and does not involve any tooling or human interference. However, the mechanical parts made by the AM method have unique problems. In particular, the effect of the strain rate on the mechanical property of Young's modulus and Poisson's ratio has not been studied in detail. Therefore, we investigated the effect of strain rates on 3D-printed ABS-like specimens in this study. In order to investigate the effect of tensile speed on 3D-printed ABS-like specimens, tensile tests were conducted at 0.2 mm/min, 2 mm/min, 60 mm/min, 800 mm/min, and 1000 mm/min. We obtained the experimental results that Young's modulus increased with increasing tensile speed. Also, the specimen broke at multiple points in high-speed tensile tests. Poisson's ratio values for all tensile speeds were almost constant around 0.38.
