The cutting blades can be removed by levering
each blade individually out of it's slot. If this proves
difficult, there are two threaded holes on each end.
Use a 25mm M3 bolt to screw down and lift each side.
*Make sure both flat surfaces of the barrel are com-
pletely clean before reassembly.*
Copper grease (provided) : When reassembling the
block it is advisable to coat the thread with this anti
seize copper solution.
Please also make sure both block surfaces are
perfectly clean. Place the top on the lower bleck and
bolt on the nozzle holder in the front (finger tight),
this will align both sections.Then tighten all eight M8
bolts on the top of the block using the torque wrench
provided (set to 24Nm). and tighten the nozzle
holder again at 24 Nm.
CHANGING THE NOZZLE
Before attempting this operation please use insulated
gloves. To switch between nozzle sizes to heat up the
unit to175c. Unscrew the nozzle, clean off any excess
plastic from the internal threads, then screw on new
nozzle
BLENDING/MIXING
All our fusionX extruder's are shipped with three sets
of hardened cutting blades. Usually these are placed
in sequence within the block. For example the 10mm
blade would be first in line, then the 3mm and lastly
the 1mm blade. This ensures a gradual hot melt
mixing set up, so by the time the material reaches the
nozzle it is thoroughly blended.
For materials that require more extensive blending,
the Noztek Pelletiser can be utilsed to cut the
filament in order to be reinserted back into the unit.
LUBRICATION
The thrust bearing assembly will require occasional
lubrication; this is a relatively simple operation,
when the barrel is split remove the screw and squirt
a 2 second burst of a lubricant like WD40 Lithium
Grease around the outer diameter of the bearing.
For optimal performance we recommend that this
procedure is carried out every 20 hours of
operation.
BARREL JAM
Depending on what type of material you are using,
you may experience a barrel jam. If at any time
during extrusion the motor starts to labour and slow
right down then you should switch off the motor
immediately. In the first instance you can raise the
temperature by 30c and turn on the motor. Failing
that, split the barrel and remove any debris
COOL DOWN
There are two fans connected to the main case: One
is to cool the motor, the other is to cool the heat sink
section underneath the hopper.
This has been installed to reduce any hopper neck
clumping when extruding at higher temperatures.
