Maintaining Your 3D Printer
4.1 Overview
Little maintenance is required keep your TAZ 3D printer running. De-
pending on your rate of use you will want to perform a quick check of your
printer every 2 to 4 weeks. The following maintenance guide lines will keep
your printer printing quality parts.
4.2 Smooth Rods
Wipe the smooth steel rods with a clean rag 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 Threaded Rods
Periodically, you will want to wipe down the threaded rods with silicone
based grease. Never use any petroleum based grease, which may compro-
mise the plastic parts. Apply the silicone grease both above and below
the X ends on the threaded rods and wipe down the threaded rods. Use
pronterface to drive the Z axis up and down to help further distribute the
lubricant.
4.4 PET Sheets
After repeated use, the PET sheet print surface will begin to wear.
Replacement PET sheets are available on
LulzBot.com
. To replace the
PET print surface, peel off the worn PET sheet from the glass print surface.
If there is any glue or plastic residue left on the glass surface, clean it with
acetone or an alcohol based glass cleaner. Peel a corner of the clear plastic
away from the green PET sheet and apply the corner of the PET to the
corner of the glass. Align the PET sheet onto the glass. Using a paper towel
begin slowly smoothing/applying the PET onto the glass while pulling back
the clear sheet from underneath the PET. You can also spray glass cleaner
onto the paper towel or the top side of the PET for a smoother application.
