Three-dimensional printed plastic products developed through fused deposition
modelling (FDM) take long-term mechanical loading in most industrial prototypes.
This article focuses on the impact of the 3D printing parameters, type of thermal
treatment and variation of characteristic dimensions of standard specimens on the
tensile properties of poly(lactic acid) (PLA) material. Two mediums were used for
thermal treatment: NaCl powder and plaster. The specimens immersed in NaCl
powder were heated to the melting temperature of the filament (200 °C), while
the processing of the plastered specimens was performed at a temperature of
100 °C. After treatment, the specimens were cooled at room temperature (25 °C),
and the dimensions of the annealed and untreated specimens were controlled.
The tensile test of the specimens was performed on the universal test machine.
The response surface methodology (RSM) is employed to predict the tensile stress
by undertaking input parameters. The a...nalysis of variance (ANOVA) results
revealed that the untreated specimens, orientation – 45/45 and layer thickness of
0.1 mm had the highest tensile stress value. Thermal treatment in plaster showed
a significant increase in tensile strength, while the best specimens were obtained
after treatment in NaCl, and all refer to the –45/45 (0.1 mm) orientation.
