“…Agarwal and Agarwal [33] tested the bisphenol-A resin with two different hardener types: triethylenetetramine (TETA) and diaminodiphenyl methane (DDM) giving a strength of 52 MPa and 83 MPa, respectively. And when using bisphenol-F as a resin with aromatic amine hardener, the strength reached 84 MPa [34].…”

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%.

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%.

“…After opening the glass mold, a flat composite plate was obtained. This mold was very useful because when it was placed vertically for the curing, all the bubbles formed during injection the resin, moved up to the top of the mold and this enable obtaining a bubble free and uniform thickness cured laminates of the samples [29]. The epoxy resin filled by 1, 2, and 4 wt.% of nano ZnO and nano TiO2 particles was casted.…”

This research was aimed to perform a symmetric investigation regarding the influence of two types of nanoparticles, on some mechanical and morphological behaviors of the Kevlar/epoxy nanocomposites. Composites were prepared by dispersing nanoparticles of nano ZnO and TiO2 at loading of 1, 2 and 4 wt.% of each in (Kevlar/epoxy) composite using high speed mechanical mixer followed by sonication, then injecting them inside the cavity of a two plates glass mold. After curing they were characterized by tensile tests, flexural test, creep test and SEM. The results showed that the maximum increase of mean stress (41%) and the maximum flexural strength was obtained for system containing 4 wt.% of both nano ZnO and TiO2 particles, i.e., EKZ4 and EKT4 . SEM images for processed specimens were taken to observe the analogy distribution of both nanoparticles through the fiber/epoxy system. The improvement in the mechanical properties of nanocomposite EKT2 (2% TiO2)and EKZ2 (2% ZnO) attributed by the homogeneity of the nanoparticles distribution inside the epoxy which appear in SEM images. Also, the semispherical shape of nanoparticles led to uniform distribution of the nano particles inside Epoxy-keflar resin.
