4. Partially screw on the FDM tip and allow it to heat up to the liquefier
temperature.
a. Start the FDM tip by screwing it into the liquefier. Do not screw the
tip all the way into the liquefier.
b. Wait for the actual temperature reading on the liquefier temperature
control (Watlow) to reach the set temperature.
5. Tighten the FDM tip very slowly with the tip wrench until it is seated
firmly against the liquefier opening. If the FDM tip has been used
before, some material might come out of the tip.
If no material comes out of a used FDM tip, it might have been
screwed on too quickly. This causes the liquefier to plug. Refer
to your FDM User Manual for instructions on how to clean the
FDM head.
6. Wait for the actual temperature on the liquefier temperature control to
reach the set temperature.
7. Snap shroud onto tips.
NOTE: The tip shroud is made from cirlex, a high-
temperature plastic. Never substitute another material in its place! Shrouds
wear out during normal operation and can be ordered from Sratasys.

Removing an FDM Tip from the FDM Head

If you need to remove a tip and replace it, follow these steps:
1. Wearing heat-resistant gloves, unsnap and remove the tip shroud, and
then unscrew the FDM tip with the tip wrench.
Make sure the tips are at the recommended modeling
temperature before removing them. This prevents the threads in
the liquefier from stripping.
ABS tips have an o-ring placed on top of the tip. (See graphic on
the next page.) Make sure the o-ring is removed with the tip.
2. Place the FDM tip in a location where it can cool. Once the FDM tip has
cooled, return the tip to its holder.
