Has anyone experienced bowing/shrinkage/warping of objects printed using a ProJet 660 printer or anything similar?
This is mostly noticeable when printing large flat objects. The corners seem to either sink into the powder bed or the centre shrinks when cooling maybe?
It can be up to 3-4mm over the length of the print bed (380mm) and in all directions but mainly along the horizontal plane. There is some slight shrinkage in the other planes too but not as noticeable.
I have tried turning the heater off after the printing cycle to see if that helps regulate the temperature in the build chamber but it hasn't made any difference.
