Ispitivanje otpornosti na plošno habanje 3D ispisanih ispitnih tijela iz akrilonitril/butadien/stirena postupkom taložnog očvršćivanja

Abstract

Additive manufacturing processes are of great importance for the development of modern production, which is why much research is being carried out to determine or improve the properties of 3D printed products depending on the desired application. In this work, the abrasion resistance of acrylonitrile/butadiene/styrene (ABS) test specimens was investigated using fused deposition modeling (FDM) for the production of shoe heels or shoe bottoms. The test was performed using the Martindale wear method on 3D printed ABS test specimens colored with disperse dyes in the depletion process and on 3D printed test specimens colored in the mass of the original ABS polymer. In accordance with HRN EN ISO 12947-3:2008 Determination of abrasion resistance using the Martindale method: determination of mass loss, the results show the mass loss in % and the change in thickness of the test specimen in %. Abrasion resistance was tested on substrates of varying fineness, with the outer and inner surfaces simulated according to the intended application. Six abrasive substrates were selected and three test specimens were tested for each substrate. The results of the test showed a higher abrasion resistance of the test specimens painted in the mass (original ABS polymer in color) compared to the test specimens subsequently painted with dispersion paints.
