ATTENTION – EXTRUDER
The fusion and extrusion system of the thermoplastic filament requires a heated end up to tempera-
tures of 250 degrees and more. The contact, even for a very limited time, with the heated part causes
burns. You must avoid to put your hands or other body parts in the printing area when printing and
for minutes after the printing process is over. The current temperature of the extruder is indicated on
the LCD screen.
ATTENTION – HEATED PRINTING BED
All the printing plate is made of metal with the addition of a glass plate. Shartebot NG may have a
heater at the pot’s bottom depending by which printer you decided to purchase. This device is elec-
trically heated and serves to bring to desired temperature the entire printing bed, including the glass
plate attached with pegs.
The temperature is measured directly on the heating plate: so the temperature of the glass plate
will be less than the one shown for several minutes after the beginning of the heating process, but
likewise it may be warmer than what is indicated on the display for several minutes after the end of
the printing due to the the phenomenon of thermal inertia. If you have the heated bed, remember
that it can be set in special cases for temperatures of 90-110 degrees, while the recommended tem-
perature for prints is usually 60-70 degrees. At these temperatures the unintentional contact does
not produce damage and burns if you retract immediately the body part that is in contact, while at
higher temperatures it greatly reduces the time necessary to create burns. You have always to check
the temperature indicated on the display before you start maneuvering like the posting of printed
piece or the removing of the glass plate on the printing bed.
