Part-Cooling Fan Strategy for PETG
Part cooling trades strength for cosmetics in PETG: 20-50 percent fan keeps interlayer bonds strong while controlling sag, with fan pushed higher only for bridges, overhangs, and short layers. Zero fan maximizes strength for functional parts; full fan like PLA noticeably embrittles the Z direction.
