Tensile properties of pure PLA polymer dedicated for additive manufacturing

This research aims to provide comprehensive data on PLA polymer tensile properties via conducted tensile tests on 100 % infill density specimens (for 0.3; 0.2; 0.1 mm layer height), and all possible lower infill results (i.e., from 90 to 10 %, with a 10 % increment) obtained by interpolation of previous research findings. Tensile tests are performed using dedicated ISO 527-2 standard. Next, the FEM analysis is performed for the 100 % case to verify the FEM model. Thus, the implemented constitutive models of this thermoplastic material and FEM simulations match the experimental data.
