3.2 Testing of Printed Specimens
The samples were printed as per ASTM-D 638 through the FDM printer. The
tensile strength was carried out using the Universal Testing Machine FIE
UNITEK-9450. The samples were tested until they broke at a speed of 5
mm/min. After testing, the fractured surface was measured with a
high-capacity microscope (ICX41M, Sunny Optical Technology Co.,Ltd.,
through Nu-Tek Solutions) at magnification levels ranging from 1000 to
3500 magnification levels. Tests were carried out in accordance with the
Design of Experiments , and the results are shown in table 6.
