Influence of nozzle temperature (T1 = 190 °C, T2 = 210 °C, T3 = 230 °C) and cooling time (3.2 s, 9.2 s, 13.7 s, 18.5 s, 23.4 s) on interfacial strength. A distinction is made between the three methods (a) IAM/E, (b) IAM/I and (c) IAM/F. To classify the interfacial strengths, the bulk material strength (solid line) is shown with its standard deviation (dashed lines). Mean values and the scatter of the interfacial strengths differ depending on the method considered.
