Make sure that the hot end and print bed are at room temperature before beginning any cleaning or maintenance unless otherwise noted.
Print Bed
Adhesion to your LulzBot TAZ Pro S modular heated print bed is the foundation of a great 3D print.
The bed can be used in three supported configurations: PEI, PEI with glue stick, or plain glass. Your LulzBot TAZ Pro S ships with the PEI
surface facing up since it’s the most commonly used print surface. Refer to the chart at the beginning of Section 7 of this guide for bed
preparation for specific materials.
Following these tips will help you get the most out of your print bed:
PEI: Oil on your skin and accumulated dust can negatively affect print adhesion to PEI. For optimal
performance, lightly wipe the print bed and corner washers with a dry lint free cloth between prints. To
deep clean the PEI print surface and corner washers, wipe with diluted Isopropyl Alcohol (1:10 IPA to
water ratio) and a clean lint free cloth.
Always wait for the PEI print surface to cool to removal temperature before attempting to remove 3D
printed objects. Treated appropriately, PEI is extremely durable, but note that even well-treated PEI will
not last forever. It will need to be replaced periodically and is considered a consumable item. Replacement
Glass/PEI Print Surfaces can be purchased at LulzBot.com
Bare Glass: The ability to print on bare glass is especially useful for TPU filament like Ninjaflex. To use the
glass surface, unscrew each corner washer holding the print bed in place with the supplied 2mm hex key,
then flip the print surface and place it back on the heater bed with the glass side up. Screw in each corner
washer to hold the bed in place. Using care not to over-tighten, make sure that the washers are flat and
parallel with the surface of the glass. If you do not wish to use the bare glass surface when printing with
TPU filament, it is highly recommended to use a PVA glue stick on the PEI surface.
PEI with Glue Stick: For some filament types, a polyvinyl alcohol (PVA) glue stick, such as Elmer’s ® brand
glue stick, is necessary for bed adhesion and/or part release. Apply the glue stick in light, even coats.
Periodically remove accumulated glue with a damp paper towel to maintain a flat, smooth base for your 3D prints.
