Hi,

I added the Raft build plate adhesion type for one of enclosure 3d print. The part is rectangular ( 95 mm x 135 mm) shape and bottom side is flat. And I kept bottom side to bed, therefore I used raft to provide more air gap to reduce any shrinkage/heat distortion.

Although after print and remove the raft layer the bottom side appear as more distortion with initial layers gap and 3d printed part bottom surface it's not smooth which on raft.

Do you guys have similar experience? and how do I improve bottom surface quality with raft build plate?

Have you tried printing directly on top of the build plate? may be Skirt or Brim build plate adhesion setting.

Yes, initially I tried with on top of Brim build plate to 3d print. Following you see there is more shrinkage issue arise in one edge area
