Replace the glass plate

The glass plate is the printing platform of the Ultimaker 2+. This sheet of safety glass provides a smooth and flat surface for printing, while evenly distributing the heat from the heated bed.

For most materials, we recommend applying a thin layer of glue to the glass to ensure good adhesion. For other materials, such as ABS and CPE, glue must be applied. This is because as well as improving adhesion, it serves as a protective layer for the glass plate. Not using glue with these materials can lead to the glass chipping when removing a print.

If the glass plate is chipped, it is recommended to replace it in order to ensure adhesion, as well as for safety.
