View source for FDM Print finishing problems

The adhesion between the print and the bed is too strong, and sometimes attempts to detach it result in damaging the bed surface.

* '''The print exhibits excessive adhesion to the bed''': reaching a point where attempts to detach it can result in damaging the bed surface, solve this issue by:
** Allow both the print and the bed to cool down, they contract at different rates, introducing tension, which makes dislodging easier.
** Use a palette knife if the bed surface is glass (never put your fingers at risk; the knife's behavior can be unpredictable when it encounters resistance or when the print suddenly dislodges).
** '''In severe cases''', if you prepared the surface with glue and the bed is detachable:
*** Submerge it in water and wait until the print loosens
*** Use IPA to soften/dissolve the glue and retry dislodging the print
** '''In an extreme case''', heat the bed-print combination in an oven and use a palette knife when everything is hot. Be aware that this may likely destroy the print (and possibly your hands if not protected)
** '''To prevent this from happening''':
*** Clean the bed thoroughly and prepare the surface again regularly
*** Avoid excessive contact area between the print and the bed; consider dividing the contact area into sections by adding shallow holes
*** Never use very cheap filament that doesn't solidify well and acts like glue in practice
* '''Hard-to-remove support''':
** Increase the air gap
** Increase the spacing of the pattern
** Decrease the support percentage
** Turn off perimeter creation
