Print Adhesion
Your LulzBot Mini 2 is equipped with a PEI print surface. This revolutionary print surface has
been tested by the advanced members of the LulzBot community and has proved to be an eas-
ier and more reliable 3D printing surface. When cleaned and heated to the recommended tem-
peratures, your print sticks well without the need for solvents or glues for most materials, the
first time and release from the print surface once cooled to the recommended filament-specific
object removal temperature.
The PEI film is adhered to the glass bed plate with a semi-permanent adhesive in order to max-
imize the lifetime of the PEI print surface. As the interface between the printer and the printed
object, the print surface sees the most abuse of any part on your 3D printer and will likely need
to be replaced at some point during the life of the printer. The PEI print surface is considered
consumable, and may need replacement periodically depending on wear.
After extended use, some printed objects may lift off the print surface on the corners, along
edges, or other areas of the print. Activate the Brim setting in Cura to help increase the surface
area of the first layer of the print to improve part adhesion.
