Mechanical Properties of Samples of Polyphenylene Sulfone Obtained by the 3D-Printing Method

The effect of process conditions on the 3D-print to physical-mechanical properties of products made of polyphenylene sulfone obtained by layering the molten polymer filament (FDM) was investigated. The dependence of physical-mechanical properties of polyphenylene sulfone on the following printing parameters: angle of orientation of yarn laying (bitmaps), the air gap between the circuits and rasters, the air gap between the raster, raster width was revealed. It is shown that the best physical and mechanical characteristics of polyphenylene sulfone close to the injection, are achieved by printing in a longitudinal orientation of the filaments with minimum width and negative clearances between them.
