“…In the investigation of PA gears, the research underscores the significance of the moisture levels in relation to the tensile strength, surpassing the influence of the printing temperature [29]. Taking into account the extruder's maximum operating temperature of 260 • Celsius, the printing temperature for the PA toothed wheel was set to 250 • Celsius.…”

This paper proposes a series of experimental determinations carried out with the aim of generating new conclusions regarding the ability of 3D-printed gears to be integrated into mechanisms without lubrication. The main factors that influence the appearance of wear in non-lubricated contact are sliding speed, material hardness, surface finish, surface geometry, and material microstructure. The tests considered the type of material from which they were made and the 3D printing technology type. For testing the gear wheels, a mechatronic experimental setup was made consisting of two shafts with adjustable axial distances, a wheel loading system gears, an electric motor, and a command-and-control system. In terms of materials, four types of materials were monitored: PA (polyamide), PLA (polylactic acid), ABS (acrylonitrile butadiene styrene) and PP (photopolymer). The evaluation of the gear wear was carried out by checking the gearing on two flanks (Frenco ZWP 06) and by scanning with the ATOS CORE 135 3D scanner. The PA and PP gears failed to meet the structural integrity standards after the tests. The PLA gears exhibited superior resistance to abrasive wear compared to the ABS gears, whereas the ABS gears generally demonstrated stronger structural integrity.

“…Among them are the following: Glass fiber-reinforced polyamide (PA-GF)—glass fibers improve the tensile strength, stiffness, and dimensional accuracy of printed parts [ 38 , 39 ]. Carbon fiber-reinforced polyamide (PA-CF)—carbon fibers added to polyamide increase mechanical strength and stiffness while reducing the weight of printed elements [ 40 , 41 ]. Aramid fiber-reinforced polyamide (PA–Aramid)—aramid fibers (e.g., Kevlar) used as reinforcement improve the wear resistance, impact resistance, and temperature stability of printed elements [ 42 , 43 ].…”

This paper shows the three-point bending strength analysis of a composite material consisting of polyamide doped with chopped carbon fiber and reinforced with continuous carbon fiber produced by means of the material extrusion (MEX) additive manufacturing technique. For a comparison, two types of specimens were produced: unreinforced and continuous fiber-reinforced (CFR) with the use of carbon fiber. The specimens were fabricated in two orientations that assure the highest strength properties. Strength analysis was supplemented by additional digital image correlation (DIC) analysis that allowed for the identification of regions with maximum strain within the specimens. The utilization of an optical microscope enabled a fractographic examination of the fracture surfaces of the specimens. The results of this study demonstrated a beneficial effect of continuous carbon fiber reinforcement on both the stiffness and strength of the material, with an increase in flexural strength from 77.34 MPa for the unreinforced composite to 147.03 MPa for the composite reinforced with continuous carbon fiber.

“…Fur-thermore, the use of polyamide 6 (PA6) as a practical matrix material in lightweight carbon fiber-reinforced, graphene nanoplatelet-reinforced, or reinforcing fibers of cement mortars is increasing [64][65][66][67][68]. Its mechanical performance under tensile and fatigue loadings in 3D printing has been thoroughly studied [68][69][70][71][72][73][74][75]. S. Terekhina et al [48] performed a fatigue investigation focused on the viscoelastic response of PA6 in FFF 3D printing.…”

Both energy efficiency and robustness are popular demands for 3D-printed components nowadays. These opposing factors require compromises. This study examines the effects of seven general control variables on the energy demands and the compressive responses of polyamide (PA6) material extrusion (MEX) 3D printed samples. Nozzle Temperature, Layer Thickness, Orientation Angle, Raster Deposition Angle, Printing Speed, Bed Temperature, and Infill Density were studied. An L27 orthogonal array was compiled with five replicas. A total of 135 trials were conducted, following the ASTM D695-02a specifications. The stopwatch method was used to assess the construction time and energy usage. The compressive strength, toughness, and elasticity modulus were experimentally determined. The Taguchi technique ranks each control parameter’s impact on each response measure. The control parameter that had the greatest impact on both energy use and printing time was layer thickness. Additionally, the infill density had the greatest influence on the compressive strength. Quadratic regression model equations were formed for each of the response measures. The ideal compromise between mechanical strength and energy efficiency is now reported, with merit related to technological and economic benefits.
