“…Moreover, Kannan et al . (2020) compared the carbon fiber reinforced PET-G parts with non-reinforced PET-G parts in a natural frequency way and noted that carbon fiber reinforced PET-G parts exhibit 17% higher natural frequency values than the non-reinforced ones.…”

PurposeThis study aims to reveal the influences of three-dimensional (3D) printing parameters such as layer heights (0.1 mm, 0.2 mm and 0.4 mm), infill rates (40, 70 and 100%) and geometrical property as tapered angle (0, 0.25 and 0.50) on vibrational behavior of 3D-printed polyethylene terephthalate glycol (PET-G) tapered beams with fused filament fabrication (FFF) method.Design/methodology/approachIn this performance, all test specimens were modeled in AutoCAD 2020 software and then 3D-printed by FFF. The effects of printing parameters on the natural frequencies of 3D-printed PET-G beams with different tapered angles were also analyzed experimentally, and numerically (finite element analysis) via Ansys APDL 16 program. In addition to vibrational properties, tensile strength, elasticity modulus, hardness, and surface roughness of the 3D-printed PET-G parts were examined.FindingsIt can be stated that average surface roughness values ranged between 1.63 and 6.91 µm. In addition, the highest and lowest hardness values were found as 68.6 and 58.4 Shore D. Tensile strength and elasticity modulus increased with the increase of infill rate and decrease of the layer height. In conclusion, natural frequency of the 3D-printed PET-G beams went up with higher infill rate values though no critical change was observed for layer height and a change in tapered angle fluctuated the natural frequency values significantly.Research limitations/implicationsThe influence of printing parameters on the vibrational properties of 3D-printed PET-G beams with different tapered angles was carried out and the determination of these effects is quite important. On the other hand, with the addition of glass or carbon fiber reinforcements to the PET-G filaments, the material and vibrational properties of the parts can be examined in future works.Practical implicationsAs a result of this study, it was shown that natural frequencies of the 3D-printed tapered beams from PET-G material can be predicted via finite element analysis after obtaining material data with the help of mechanical/physical tests. In addition, the outcome of this study can be used as a reference during the design of parts that are subjected to vibration such as turbine blades, drone arms, propellers, orthopedic implants, scaffolds and gears.Social implicationsIt is believed that determination of the effect of the most used 3D printing parameters (layer height and infill rate) and geometrical property of tapered angle on natural frequencies of the 3D-printed parts will be very useful for researchers and engineers; especially when the importance of resonance is known well.Originality/valueWhen the literature efforts are scanned in depth, it can be seen that there are many studies about mechanical or wear properties of the 3D-printed parts. However, this is the first study which focuses on the influences of the both 3D printing parameters and tapered angles on the vibrational behaviors of the tapered PET-G beams produced with material extrusion based FFF method. In addition, obtained experimental results were also supported with the performed finite element analysis.

“…In another study, Özen et al [23] optimized the sample geometry so as to enhance mechanical properties of the PETG samples fabricated by FDM. Kannan et al [24] found severe flow lines after the tensile tests in the 3D printed PETG specimens, so they recommended that samples could be improved with fiber reinforcements.…”

Additive manufacturing (AM) is a highly popular, versatile, and practical production technique due to its great ability of very fast prototyping. Compared to other traditional ways, the number of studies on AM techniques has increased in a noteworthy manner day by day on account of their promising potential for future works. In this paper, fused deposition modeling (FDM) technology was used to fabricate polyethylene terephthalate glycol (PETG) specimens and to analyze the effect of the test speed on their tensile properties. As for the printing parameters, solely layer thickness values (0.1 mm, 0.2 mm, and 0.4 mm) were altered while the other factors were kept constant. In order to ascertain the production effectiveness, hardness and surface roughness measurements were carried out. Uniaxial tensile tests were performed at three different test speeds: 5 mm/min, 25 mm/min, and 50 mm/min. Furthermore, after deformation inspections were conducted both in macro and micro scales to evaluate the failure better. From the damage analyses, it was seen that ductile dominant mixed type failure is valid for lower test speeds even though brittle dominant mixed type failure is detected for 50 mm/min test speed.

“…Few have been encapsulated and discussed here.

In this study, the experimental results of the modal analysis of additive manufactured glycol-modified polyethylene terephthalate (PETG) based composites reinforced with short carbon fibers and organically modified montmorillonite (OMMT) nanoclay (NC) is presented. The raw materials are compounded and extruded using the twin-screw extruder. The specimens in the beam form are prepared through the fused deposition modeling process, one of the prominent additive manufacturing techniques. The individual and combined effect of reinforcing OMMT nanoclay and short carbon fibers on the natural frequencies and damping factors of PETG composite is investigated by varying their weight percentages. Further, a comparative study is made with the vibration response of pure PETG beam as well. The experimental set-up constituted of an accelerometer, impact hammer, and data acquisition unit is used for vibration studies. Two different boundary conditions, viz. cantilever and clamped constraints, have been incorporated in this investigation. The experimental results reveal that boundary conditions and the weight percentage of reinforcements play a vital role in deciding the frequency and damping parameters of the PETG composite beam.
