5.1 Static Testing

5.1.1 Differential Scanning Calorimetry (DSC)

The melting and crystallization characteristics of filaments and prints with H–H60 mixtures are estimated using a PerkinElmer DSC-6000 from the USA. In a 30 L Al crucible, a 10 mg sample is heated to a temperature range of 0–200 °C and then isothermally cured for roughly 3 min at 200 °C. After removing the thermal history caused by previous processing phases, samples are cooled down to 0 at 10°/min. After three minutes of chilling at 0 °C, the cupons are heated from 0–200°C. Exothermic and endothermic peaks, which indicate enthalpy of melting at cold crystallization, can be seen on DSC graphs. It is determined that Crystallinity% () is [1],
