AB  - The 3D printing parameters are known to have a significant impact on manufactured
parts, and the layered morphology of these parts makes mechanical design analysis for
engineering applications difficult. In this work, the tensile strengths and microhardness
of 3D printed polylactic acid (PLA) specimens with different orientations and numbers
of individual layers of mesh material (polyvinyl chloride – PVC) were investigated as a
laminate composite. Composite specimens were obtained using 3D printing via fused
deposition modelling (FDM). Moreover, the influence of printing parameters (i.e. infill
density and layer height) and the number and orientation of reinforced meshes on the
mechanical response was investigated. Fracture strength of PLA/PVC laminate
composites ranges from 31.30 MPa (3 PVC mesh layers; mesh height position:
25 % │ 50 % │ 75 %; infill density: 60 %; PVC mesh orientation: 90° │ 45° │ 90°; layer
height: 0.2 mm) to 18.62 MPa (without PVC mesh; infill density: 30 %; layer height: 0.1
mm) demonstrating a significant impact of the number of the PVC mesh layers, infill
density of PLA and layer height on the final mechanical parameters of printing
PLA/PVC elements. The surface hardness at the micro load level showed that the
number of reinforcement layers affects the microhardness value, as well as material
filling and mesh orientation. The specimen with the following parameters gave the
best results: layer height: 0.2 mm; 3 PVC mesh layers; infill density: 60 %; PVC mesh
orientation: 90° │ 45° │ 90°. The average hardness values for one layer and three layers
of mesh were in accordance with tensile test results.
