3. Results Testing of the adhesion strength between the layers was performed on a stretching machine while the results were digitally recorded and read from the desktop. Table 3 shows the force values for the layer height of 0.1 mm . For this layer height, five specimens were tested and the maximum force obtained in this case was 118.7113 N.

The next five specimens that were tested, were for layer height of 0.15 mm . In this case, the force was significantly lower, and the results are shown in Table 4.

The last five specimens that were tested were for layer height of 0.2 mm . The maximum force obtained in this case is also the overall maximum force, which has the value of 133.1641 N and is shown in Table 5.
