7 - Printing behaviour of thermoplastic materials

One of the most critical factors in the current 3D printers is the surface treatment of the printing plate. When the filament is extruded, the first layer must be daub by the

nozzle on the printing surface.; i f by cooling down, the plastic loses grip, the printing process can fail, or decrease in quality, because of the detachment of the printed
part from the printing bed. There is not a unique solution for all types of filament to be printed. Let's analyze the behaviour of the PLA during printing.
