Evaluation of Anisotropy of Additively Manufactured Structures
Original language description
This work focuses on evaluating the anisotropy of the structures manufactured by two 3D printing technologies, Fused Filament Fabrication (FFF) and Stereolithography (SLA). According to the manufacturing process, printed structures are expected to have some level of anisotropy. It is essential to consider it while designing a model for 3D printing. Printed specimens were subjected to tensile testing, thermomechanical analysis (TMA), and dynamic mechanical analysis (DMA). Measurements were based on the ASTM D638, E1545 and D4065 standards. The specimens were printed in three different orientations for tensile tests and DMA, respectively in four orientations for TMA. The FFF specimens were prepared from poly-lactic acid (PLA) with different extruder temperatures, 210°C and 240°C. In the case of SLA specimens, photopolymer based on epoxy resin was used, the process differed in curing time (8 s and 16 s). The results clearly showed a higher level of anisotropy of the FFF specimens compared to SLA specimens. The FFF specimens show in the orientation XZ 1,5 times lower tensile strength than in the other two orientations, compared to SLA, where the tensile strength was similar. The anisotropy of the thermomechanical properties was high for FFF specimens; in contrast, the SLA specimens showed no difference in thermal expansion for different printing orientations.
