“…Some researches focused on improving the overall mechanical properties of the 3D printed part by decreasing its anisotropy or increasing its isotropic behavior [24,25]. They replaced the thermoplastic polymers that result in poor chemical and thermal properties with two-component epoxy resin [24], epoxy resin has good chemical and physical properties and gives high-strength bonding, with light weight structures withstanding high static loads [26][27][28]. Filippova et al [25] impregnated ABS 3D printed samples in epoxy resin compound with different hardeners.…”

The spread of 3D printing in many different fields has become eminent. This paper aims to improve the mechanical properties of parts printed by fused deposition modeling technique. Acrylonitrile butadiene styrene (ABS) specimens are printed with custom printing parameters. These parameters give a tensile strength that is 86% of the injection- molded ABS strength, and give one of the best recorded results for 100% infill printed ABS tensile specimens. Furthermore, a post filling technique has been studied. Specimens are printed with inner voids and different densities using slicing software. Void shape is precisely selected to conform to the filling process. High-strength, low-cost thermoset resin is injected through specimens to fill those voids. A tensile test has been performed after the full curing of the resin. A morphology analysis is done. Using this technique strength to printed weight ratio is improved by 151% and the cost is reduced by 51%.

“…142% and 133% were achieved as an improvement in ultimate tensile strength depending on the hardener type. Instead of impregnation, Belter and Dollar [24] injected epoxy resin through ABS exural specimens. This results in improving the overall part stiffness and strength by up to 25% and 45% respectively.…”

No one can deny the widespread of 3D printing in many different fields. This paper aims to improve the mechanical properties of parts printed by fused deposition modeling (FDM) technique. Acrylonitrile butadiene styrene (ABS) specimens are printed with custom printing parameters, these parameters give a tensile strength that is 86% of the injection molded ABS strength, and give one of the best results recorded for 100% infill printed ABS tensile specimens. Furthermore, a post filling technique has been studied, specimens are printed with inner voids and different densities using slicing software. Void shape is precisely selected to conform to the filling process. High-strength low-cost thermoset resin is injected through specimens to fill these voids. A tensile test has been performed after full curing of the resin and a morphology analysis is done. By this technique strength to printed weight ratio is improved by 151% and the cost is reduced by 51%.

“…Composites consist of two main structures: the base matrix, which is the core element, and the additives or reinforcements embedded in the base matrix [1]. In metal matrix composites (MMC), the base matrix is metal [2], and reinforcements can be any other structure, such as nanoparticles [3], nanotubes [4], nanorods [5] or nanofibers [6,7]. According to Adebisi et al [8], aluminum is the most common metallic material that can be used as a matrix material, owing to its high strength, acceptable thermal and electrical conductivity, better corrosion and electrochemical behavior [9].…”

This study is focuses on the investigation of the effect of using TiO2 short nanofibers as a reinforcement of an Al matrix on the corrosion characteristics of the produced nanocomposites. The TiO2 ceramic nanofibers used were synthesized via electrospinning by sol-gel process, then calcinated at a high temperature to evaporate the residual polymers. The fabricated nanocomposites contain 0, 1, 3 and 5 wt.% of synthesized ceramic nanofibers (TiO2). Powder mixtures were mixed for 1 h via high-energy ball milling in a vacuum atmosphere before being inductively sintered through a high-frequency induction furnace at 560 °C for 6 min. The microstructure of the fabricated samples was studied by optical microscope and field emission scanning electron microscope (FESEM) before and after corrosion studies. Corrosion behavior of the sintered samples was evaluated by both electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques (PPT) in 3.5% NaCl solution for one hour and 24-h immersion times. The results show that even though the percentage of ceramic nanofibers added negatively control corrosion resistance, it is still possible to increase resistance against corrosion for the fabricated nanocomposite by more than 75% in the longer exposure time periods.
