“…Therefore, as mentioned in Figure 8, it is mostly used for rope, carpet, clothing, and packing, and its extruder melt temperature is calculated from 220 °C to 250 °C. Also, PP is slightly more flexible than PLA [81][82][83]. In all polymer filament materials, composite filaments are available in the market with 90% parent polymer and 10% another polymer according to the application, for example, ABS+, ABS Premium, PLA Pro, PLA+, PLA carbon fibre, and PETG carbon fibre [91][92][93][94].…”
