After the printing, there are some ways to remove the print from the build plate depending on different situations.
The filament (which forms the print) shrinks as the temperature drops, thus weakening the adhesion between the print and the build plate.
Therefore, the easiest way in most cases is to wait until the build plate and the print naturally cool down to indoor temperature and take the print off with the least effort.
When printing on the PEI-coated side, do not attempt to remove the print when the temperature of the build plate is still over 40℃. Otherwise, the PEI coating may be damaged.
Wait for the temperatures of the heated bed to drop to room temperature. Remove the PEI Sheet from the heated bed and bend it slightly to remove the print.
This method is only applicable if you are using a PEI sheet printing platform.
The nozzle and the heated bed are still extremely hot right after printing.
If the print still sticks to the build plate after the natural cooldown, you can try the removal with the provided palette knife:
Keep the angle between the palette knife and the build plate smaller than 30° to avoid damaging the PEI coating.
The knife should be pointed far away from the human body to avoid injuries caused by the blade or the fall-off print.
If you fail to remove the print even with the palette knife, you can rinse the build plate with cold water to accelerate its further cooldown:
Do NOT directly rinse where the print adheres to the build plate lest the print deforms due to excessive shrinkage.
Do NOT rinse the build plate before it has yet cooled down to indoor temperature. Otherwise, the build plate might crack due to thermal contraction.
If you are using a glass printing platform and applying water-soluble glue to the build plate before printing, you can remove the adhesive residues with warm water:
