In the present work, specimens have been printed according to ASTM standards on a 3D FDM printer using the PETG material and conducted tensile, compression tests respectively by varying the layer height parameters and infill percentages respectively. The experimental results are then to be validated ...

Fair interlayer diffusion and a good diffusion between the pairs of deposited material for each layer height can be seen. This arrangement of pairs of the deposited material also confirmed visible air voids already detected by the XCT results. From the images, perceptible nucleation points and ...
The experimental results showed that layer height and infill density predominantly affect the flexural strength, while the print speed and infill density most affect the hardness and the tensile strength of 3D printed samples. Besides the mechanical properties, printing parameters were also found to ...
The polymer foil industry is one of the leading producers of plastic waste. The development of new recycling methods for packaging products is one of the biggest demands in today’s engineering. The subject of this research was the melt processing of mul
