Tribological properties of 3D printed components

Abstract

Additive manufacturing technology is developing in many industries, including aviation, automotive and others. 3D printing offers new possibilities in the field of designing and manufacturing of machines and devices’ components. The paper presents the results of tribological investigations of components produced in FDM printing technology. The authors presented the evaluation of sliding properties of the model friction couple – block on ring type – of available thermoplastic polymers and polymers’ composites under dry friction conditions. The authors assessed the influence of material type and printed structure on resistance to motion of prepared samples.

Orientation Controls Tribological Performance of 3D-Printed PLA and ABS

“…Comparison of tribological properties of polymers made from injection molding and additive manufacturing techniques were reported by Pawlak et al [19]. In terms of different layer orientation, tribological properties of polymers printed at 0, 15, 30, 45, 90 degrees were reported in some recent research works [18,21,[25][26][27]. Effect of print temperature and filament color has been also studied [28].…”

“…As mentioned earlier in the literature section, the utilization of a steel ball counterface in a reciprocating tribometer reduces the measurement uncertainty significantly compared to rotating disk methods mentioned in the literatures. In addition to the applied method of measurement, the length of the test performed in this paper offers further insight into the wear properties of 3D printed PLA and ABS as current literature mainly focuses on the short-term wear results [18][19][20][21][22][23][24][25][26][27][28][29]. In the current literature, most tribological experiments lean towards utilizing a pin-on-disk method that would test samples for less than 1000 m of sliding distance.…”

Daño en partes de manufactura aditiva reforzadas por fibras continuas

“…El contacto y las propiedades tribológicas de partes impresas en 3D han sido estudiadas por Giemza et al [72], sin embargo, los autores no pudieron encontrar estudios específicos a partes FRAM. Caminero [73] estudió la influencia de 4 parámetros como son la arquitectura de la impresión (dirección de construcción), el tipo de fibra: carbono, Kevlar o de vidrio, el contenido de fibra como fracción volumétrica y el espesor de la capa en la resistencia al impacto de piezas FRAM.…”

Bending Strength of Polyamide-Based Composites Obtained during the Fused Filament Fabrication (FFF) Process

“…In the case of AM technologies, PA-based materials are broadly used in the fused filament fabrication (FFF) and selective laser sintering (SLS) methods [ 5 , 6 , 7 , 8 , 9 ]. By means of those two methods, it is possible to obtain the geometrically complex parts and nonstandard components, which are characterized by relatively good performance properties and their production is relatively inexpensive in the case of low-volume production [ 10 , 11 , 12 , 13 , 14 ].…”
