Overview
The extruders are the main unit for 3D printing with the BigRep ONE. The extruder
contains the hot end (n) where the filament is heated and then squeezed through
the nozzle (o).
The BigRep ONE is equipped with two extruders which can be changed individ-
ually. Given the two extruders, the two nozzles can be used simultaneously for
separate printing projects (with the same or diering diameters), e.g. to print ad-
ditional support material for supporting structures alongside the main object.
If you want to use other nozzle diameters than the ones installed, the extruders
need to be retrofitted. You can either replace the entire extruder or only the hot
end. In both cases the extruder must first be removed from the machine.
