Print Heads

The F123 printer utilizes five print head assemblies, one for standard model and support
material, one for TPU 92A (Elastomer), one for ABS-CF10 model material, one for PLA model
material, and one for the PLA cooling module. The standard model and support heads are
black. The TPU 92A model head is blue. The PLA head is dark gray. Once a head has been
used for standard model or support, it can only be used for that designated material (model or
support) thereafter. The TPU 92A head can only be used for TPU 92A material. The ABS-CF10
head is green and can only be used with ABS-CF10 material. The standard model material
head can be used with ABS-CF10 material (even after standard materials have been used),
but head life will be negatively impacted due to the carbon filled material. The standard head
can be used exclusively with ABS-CF10 material, but the head life will be 700 hours. Also, the
head life warranty for the standard head is not guaranteed if a mix of standard material and
ABS-CF10 material is used. While standard material may be used after ABS-CF10, it is not
recommended for Diran which will exhibit poor part quality. The PLA head can only be used for
PLA material. The heads are designed for use with a range of modeling materials. The heads
extrude model material and support material with two identical liquefiers. A single blower fan,
mounted above the tip liquefier entrances, cools the incoming material at the liquefier
entrances.
Head life is directly related to the amount of build time for the head. Heads are a replaceable
consumable item and should be changed once the head's odometer reaches 1500 build hours
(see "Viewing Head Details" (page 64)
warning when the head's odometer reaches 1350 build hours, reminding you to order a
replacement head as the head is nearing its odometer limit. The standard head life will diminish
if ABS-CF10 material is used. Head life for both a standard head and the dedicated ABS-CF10
head is limited to 700 hours. The warning for the ABS-CF10 head occurs at 600 hours. You can
continue using a head which has exceeded its odometer limit, but it is highly recommended
that you change the head as part quality will be unpredictable. The corresponding Head Status
Icon will be displayed in its warning state on the User Interface
states). The entire model or support head assembly is replaced as a single unit (see

When building with PLA material, a specialized PLA head is used. The PLA head must be
installed into the model head location within the gantry. A cooling module is used in conjunction
with the PLA model head and must be installed into the support head location within the gantry
