Wear behavior of FDM parts fabricated by composite material feed stock filament

Abstract

Purpose In this study the friction and wear behavior of fused deposition modeling (FDM) parts fabricated with composite material and acrylonitrile butadiene styrene (ABS) material feedstock filament were realized and compared under dry sliding conditions. Design/methodology/approach The tests were performed by applying the load of 5, 10, 15 and 20 N with sliding velocity of 0.63 m/s for the duration of 5 and 10 min at room temperature. Findings The results highlight various wear mechanisms such as adhesion, abrasion and fatigue during the investigation. It was observed that the wear volume, friction force, friction co-efficient and temperature were sensitive to the applied load and time duration. The composite material showed a remarkable improvement in wear properties as compared to the ABS material. Research limitations/implications The investigations reported in the present research work is based on comparative analysis (of composite material and ABS material feedstock filament). The results may be different in practical applications because of different operating conditions. Practical implications The parts fabricated with proposed composite material feedstock filament are highly wear resistant than basic ABS filament. This may lead to the development of better wear resistance components for numerous field applications. Originality/value The potential of this research work is to fabricate FDM parts with composite material feedstock filament to cater need of wear resistant industrial components.

Comparison of wear behavior of ABS and ABS composite parts fabricated via fused deposition modelling

“…The results show that composite material has less coefficient of friction as compared to pure ABS material. This result with an agreement other finding (Garg and Singh, 2015;Xu et al, 2010;Singh Boparai et al, 2016;Srinivas et al, 2012). The coefficient of friction initially has a higher value because of high resistance faced by pin when sliding on fresh abrasive surface and it becomes steady as the test continues (Singh Boparai et al, 2016).…”

The coefficient of friction initially has a higher value because of high resistance faced by pin when sliding on fresh abrasive surface and it becomes steady as the test continues (Singh Boparai et al, 2016). This result indicates that the parts produced by FDM have asperities which get surfaced out, and after sometime, as the asperities are smoothened, the coefficient of friction decreases and becomes stable as much of material is worn out in the form of powder.…”

Comparative study regarding the wear of gearwheels manufactured through additive technologies

“…The experimental stand designed and realized by the authors aims to check the wear of the gearwheels (the tooth profile, the bottom land, the state of the gear surfaces) obtained by additive technologies [7][8][9]. The stand is 1:1 using a JGA 25-370 -6V gearmotor with 58 rpm as the power source, the drive wheel is made using FDM (Fused Deposition Modelling) technology and the OLC 50 driven wheel.…”

Avaliação do desgaste de peças produzidas por manufatura aditiva FDM

“…Ainda sobre o comportamento de desgaste de peças produzidas por FDM submetidas a desgaste deslizante, em outro estudo Boparai et al (2016) mostrou que os mecanismos de desgaste que ocorrem em peças de ABS são adesão e fadiga.…”
