6.4.1 Maintaining interior surfaces
The internal surfaces of the Form Cure L are covered in a reflective coating that reflects the
light from the LEDs and ensures that parts post-cure evenly. If the reflective coating is damaged
or covered, parts may not post-cure properly.
Visually inspect the internal surfaces of the Form Cure L for traces of resin, cracks, or
other damage.
Resin will harden during post-curing. Cured resin blocks light and must be removed. If parts
are washed but not fully dry before post-curing, certain washing solvents, such as tripropylene
monomethyl ether, may evaporate and form deposits on the interior surfaces of the Form Cure L.
These deposits cloud the reflective coating and prevent parts from post-curing properly. Clean
the reflective coating as needed. Use isopropyl alcohol to clean the reflective coating and
allow isopropyl alcohol to fully evaporate before starting a post-cure cycle.
6.4.2 Maintaining the light diffusers
The primary 375 nm and 405 nm LEDs and secondary white LEDs in the Form Cure L are
covered by frosted light diffusing panels. These light diffusers spread the light from the LEDs
and ensure that parts post-cure evenly. If the light diffusers are damaged or covered, parts
may not post-cure properly.
Visually inspect the light diffusers for traces of resin, cracks, or other damage. Resin will harden
during the post-curing.
Cured resin blocks light and must be removed. If parts are washed but not fully dry before post-
curing, certain part washing solvents, such as tripropylene monomethyl ether, may evaporate
and form deposits on the interior surfaces of the Form Cure L.
These deposits will coat the light diffusers and prevent parts from post-curing properly. Clean
the light diffusers as needed. Use isopropyl alcohol to clean the light diffusers and allow
isopropyl alcohol to fully evaporate before starting a post-cure cycle.
6.4.3 Maintaining the door
Visually inspect the door for traces of resin, cracks, or other damage. Clean the door with a non-
abrasive microfiber cloth and soapy water or a general purpose cleaner, such as glass cleaner.
6.4.4 Maintaining the touchscreen
Visually inspect the touchscreen for any traces of resin. Check that the touchscreen responds
to inputs. Clean the touchscreen with a non-abrasive microfiber cloth and a general purpose
cleaner, such as glass cleaner.
