Safety Guidelines
Extruder
In FFF technology 3D printers, the thermoplastic filament is melted in the
nozzle (the terminal part of the extruder) at a temperature varying
between 190 and 500°C. During the printing process you mustn't touch
the nozzle with hands. The contact even for a very short time causes
burns. In case of routine maintenance or for replacing the nozzle, you
have always to use protection items required for hands and eyes
protection. The extruder temperature is always visible on the main display
screen.
Heated printing plate
Under the printing surface, it is placed the heated plate which is used to
improve adhesion of the model during the printing process. The heat
generated by the heated plate is also transmitted to the printing surface.
The heated surface reaches a maximum temperature of 90°C and
remains high even after the end of the printing job, also when the
machine is turned off. The contact with the plate at high temperatures
causes burns.
