Applying a new Kapton film
The Kapton film of the print bed wears out over time or can be damaged by the nozzle due to in-
correct calibration or removal of the printed models.

is damaged�

⇒ Clean the surface of the build plate with acetone�
⇒ Remove the plastic protective film (save for future use) from the sticky side of the new Kapton film.
⇒ Apply a little window cleaning fluid to the build plate and to the sticky side of the Kapton film so that you
can position the Kapton film properly on the build plate.
⇒ Place the Kapton film on the build plate so that the distance to the opposite sides is approximately the
same�
⇒ Once the positioning is correct, place the protective film (removed at the beginning) on t he new Kapton
film to avoid scratches and damage during the following operation.
⇒ Squeeze out the excess liquid between the build plate and the Kapton film with a thin but firm object
(e.g., with a used credit card).
⇒ Start in the center of the build plate and move horizontally and vertically� Once all the liquid has been
squeezed out and the Kapton film has been properly applied, set the build plate aside to dry.
⇒ Leave the build plate with the new Kapton film for a day before use.
⇒ Cut off any overhanging film flush using a knife.
