Product Usage Instructions
Power Switch and Start Up
To begin, first use the power switch on the side of the machine to power up. Powering up will take just a few moments, after which you’ll use the touch screen to set all extruding parameters and set the machine to begin.
Touch Screen Interface
- HOME: This screen shows all your settings and appears red to begin with as nothing has been set. When you have defined your settings, press MENU to begin setting up your machine.
- MENU: This is where you reach all settings.
- SET TEMPERATURES: Here you can set the mixing temperature and the extruding temperature. Use the slider and/or the + and – buttons to control the settings. You are able to set two temperatures, the extruding temperature and the mixing temperature. The warm-up heater at the base of the barrel is for reference only. Press SET to confirm your settings.
- WARM-UP: This screen has a timer to allow the machine to warm to the correct temperature. You will not be able to escape this screen until the warm-up is complete, at which time, you will return to the HOME screen.
- SET SPEED: This sets your extrusion speed. Maximum speed is 17rpm.
- SET TIMER: This represents the time you want to extrude the material. The machine will run for this set time once you have switched on the motor. If no value is entered here, the machine will run until you manually end the run yourself. This timer will pause if you pause the motor and recommence when the motor is turned back on.
- COOL DOWN: This screen will show while the cool down is happening. The default is 62 minutes. Cancelling the cool down timer will take you back to your extrusion run. Please run the full cool down before switching off the machine. Do not touch the barrel before this cool down timer has finished. Switching off a hot machine can cause serious injury.

CLEANING
- Make sure that most of the material has been extruded from the barrel before cleaaning
- When cleaning in situ, please use the fusionX protective cover provided to protect the main body of the machine from any chemicals used in the cleaning process.
- The cover has been custom made for the machine, please place each tab between the cables and fixtures underneath the barrel and the motor (back lays down first). Use the velcro to keep the cover pieces in place.
OPENING THE BARREL
These instructions are for cleaning the barrel in-situ. If you would like to remove it and clean away from the base, please follow instructions to do so in the next section.
- Unscrew the 4 bolts connecting the motor casing, pull motor casing back or remove.
- Unscrew the two front and two rear grub screws connecting the couplings to the screw and pull this back until the coupling has disengaged from the screw spindle.
- Remove both thermocouple couplings (one connected to the nozzle and the other on top of the block).
- Remove the front nozzle and unbolt the front nozzle bracket (5 x M8 bolts),
- Remove the 10 M10 bolts on the top of the block
- Located on the top block are four M5 allan bolts (‘block splitters’). Screw down each corner 5 or 6 turns and continue until the top block splits apart from the bottom section.
- To remove the screw gently lift the front tip and the screw should come loose from the bottom barrel block (Depending on the type of material debris in the barrel a solvent may be required to assist the removal process).
- 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 completely 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.
REMOVING BARREL FROM THE BASE
If you are using solvents to clean the barrel, you will want to remove the barrel from the base of the machine. You can do this by following the steps below. Please refer to the diagram. Please first perform steps 1-4 as above. As you’ll be opening the barrel eventually, it’s recomended that you also loosen the bolts in step 5 while it’s all attached to the base as they are quite tight and the base acts as a stabalising jig. Next, unscrew the bolts below the barrel, above the barrel feet, highlighted in the diagram below.
CHANGING THE NOZZLE
- Before attempting this operation please use insulated gloves. To switch between nozzle sizes to heat up the unit to 175c.
- 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.
