Abstract:
The increasing use of products manufactured by applying additive
technologies encourages using materials with better mechanical properties.
Depending on the type of material, its initial state, structure and mechanical
properties, materials can be categorized differently. Combining polymer
materials with different mechanical properties into composite structures
makes it possible to obtain materials with better mechanical properties,
which are then used on printers based on fused deposition modeling (FDM)
3D printing technology. This paper investigates the mechanical properties of
samples made by combining Polylactic Acid (PLA) and Acrylonitrile
Butadiene Styrene (ABS) polymer materials. The samples were produced
with different proportions of the two materials regarding the number of
layers and the infill density. The test was performed according to ISO 527 –
2: 2012 on a Shimadzu AGS-X 10 kN tensile test machine. For comparison,
control samples of PLA and ABS materials were printed with 100% infill and
showed the highest average force. Samples with a combination of materials
did not produce the expected better results than samples made from one
material. The reason for this is the occurrence of delamination of individual
layers.
