Maintaining Your 3D Printer
4.1 Overview
Little maintenance is required keep your LulzBot
™
TAZ 3D printer running.
Depending on your rate of use you will want to perform a quick check of
your printer every 2 to 4 weeks. The following maintenance guidelines will
keep your printer printing quality parts.
4.2 Smooth Rods
Wipe the smooth steel rods with a clean cloth or paper towel. The linear
bushings leave a solid lubricant that builds up over time. Hearing squeaking
noises while the printer is printing is likely a sign that the smooth rods need
to be cleaned. NOTE: Never apply any lubricant or cleaning agent to the
smooth rods; the bushings are self-lubricating.
4.3 Lead Screw Drive Rods
Periodically, you will want to wipe down the threaded rods with a lithium-
based grease. Never use any petroleum based grease, which may com-
promise the plastic parts. We utilize Lucas white lithium grease NLGI #2.
Apply the lithium grease both above and below the X ends on the threaded
rods and wipe down the threaded rods. Use your preferred printer host
software or the Graphical LCD controller to drive the Z axis up and down
to help further distribute the lubricant. Wipe o any excess.
4.4 PEI Surface
After repeated use, the PEI print surface will begin to need cleaning.
To clean the PEI print surface, Wipe clean with watered-down Isopropyl
Alcohol 10:1 IPA to water ratio and a clean cloth. If you encounter
prints lifting from the PEI surface, use a ne grit sandpaper, typically 2000-
2500 grit to clean the PEI print surface. We do not recommend printing on
bare glass, as it can lead to glass bed damage or failure. Never use acetone
to clean the PEI print surface as doing so can damage the lm.
