formlabs Form 3 Manual page 25

Remove the build platform, resin tank, and resin cartridge to access the drip catcher, which
is the area below the resin tank spout or under the resin cartridge dispensing mechanism.
Visually inspect the drip catcher. Clean any traces of resin or contamination with isopropyl
alcohol (IPA) and paper towels.
Inspect the Shells
6.4.4
Visually inspect the rear, front, side, and top shells for traces of resin or other damage. Clean
any traces of resin or contamination with soapy water and paper towels.
Inspect and Lubricate the X- and Z-axes
6.4.5
Disconnect the power cable. Moving parts and lead screws present crushing and
tangling hazards.
WARNING
Wear clean gloves to handle the lead screw and lubricant.
To inspect the X-axis:
1. Manually rotate the X-axis lead screw.
2. As the LPU housing moves right and left, listen, look, and feel to check for areas that emit
noise or where the carrier sticks or move less smoothly.
3. Visually inspect the X-axis to ensure that no debris or foreign objects obstruct the lead
screw or path of motion.
4. Visually inspect the X-axis to ensure that lubricant covers the full length of the threads.
To inspect the Z-axis:
1. Manually rotate the Z-axis lead screw.
2. As the build platform carrier moves up and down, listen, look, and feel to check for areas
that emit noise or where the carrier sticks or move less smoothly.
3. Visually inspect the Z-axis to ensure that no debris or foreign objects obstruct the lead
screw or path of motion.
4. Visually inspect the Z-axis to ensure that lubricant covers the full length of the threads.
In the case that the screw is missing lubricant or if the X- or Z-axis emits intermittent noises
when printing, lubricate the lead screw.
To lubricate the X- or Z-axis lead screw:
1. Remove the build platform and resin tank.
2. Place a clean low-fiber paper towel over the tank carrier and LPU housing.
3. Remove old and dirty grease from the lead screw using a paper towel.
4. Apply a light layer of lithium grease evenly along the lead screw. Apply the lubricant
directly from the container or by dabbing lubricant onto the lead screw with a
gloved hand.
5. Manually rotate the lead screw.
a. Z-axis: As the build platform carrier moves up and down, listen, look, and feel to check
for areas that emit noise or where the carrier sticks or moves less smoothly.
b. X-axis: As the LPU housing moves right and left, listen, look, and feel to check for areas
that emit noise or where the carrier sticks or moves less smoothly.
6. Wipe excess lubricant from the leadscrew with a microfiber cloth or low-fiber paper towel.
7. Reconnect the power cable.
