What is the best build surface for PETG?
Removable steel spring sheet with PEI textured coatings
I have been using textured PEI string sheet for most of my prints, just love it.
Prints attach so good but not hard to remove(with proper nozzole Z-offset).
If the prints are small and seems hard to remove,heating up the bed helps a lot.
Almost never used the smooth side, even with proper z-offset, it still damages the surface quite fast.
