Composite thermoplastic materials for filament production in 3D printing technology

This study examines the methodology for producing 3D-printing filaments from industrial polyamides. Novel compositions and a modification technique were developed for semi-finished products using an aqueous polymer solution based on tall oil rosin amides and a polycondensation product of adipic acid with diethylenetriamine, along with dispersed byproducts from electroerosive processing of tool steels with a graphite electrode. The results demonstrate that the developed filaments enhance the stress-strain properties of 3D-printed products due to the implementation of a multilevel polymer matrix modification concept through the introduced components.
