strand, thus enabling bicolored prints, printing
two materials or two objects simultaneously or
printing with different extrusion thicknesses (e.g.
for outer contours and inner filling structures).
The left (primary) hot end is configured for
standard single-extruder prints and is the
reference nozzle for leveling the print bed. The
right hot end is only leveled passively after the
print bed has been aligned correctly with the
primary hot end.

Aluminum hot-end mount (cooling block)
with thumb screw and cooling hose adapter
10 Stainless steel barrel

Ceramic 500°C heating cartridge with
integrated thermocouple
Each hot-end is heated by a ceramic heating
cartridge so that the filament is molten inside
the nozzle. The integrated thermocouple
provides direct alignment of set and actual
temperature.
To improve the thermal control of the melting
process the hot-end mount is connected to the
cooling system, ensuring an even temperature
distribution in a well defined area of the nozzles
so that there is a preheating zone and a melting
zone.
Extruder head components
The nozzle is
exchangeable
to provide different
bore diameters for different materials, layer
thicknesses or print speed. Ex factory, the
0.35mm tip is preinstalled. Additionally, three
nozzles with diameters of 0.25mm, 0.5mm and
0.75mm are included. The tips are
distinguishable by the engraved markings.
The 0.35mm and the 0.5mm nozzles should be
used for most purposes and can be operated at
an extrusion speed of up to
60mm/s. The
Slic3r profiles
provided by
Kühling&Kühling are optimized for the 0.35mm
nozzle. Additional information can be found in
the
Service Guide
and in the
Slic3r manual
.
Please try and find the settings best suited for
your task. The Slic3r profiles will be constantly
updated and extended.
The 0.75mm nozzle is primarily intended for
Markings to distinguish nozzle sizes.
