An Enclosure will not always do the trick if you print with ASA or ABS.
It will always depend how large and how much infill an object is / has.
Even ABS will need cooling in an Enclosure and that might be already the tip where it will warp.
I´m testing Nice ABS and it doesn´t tend to warp with big objects and zero cooling.
But small objects will need the cooling or they will just melt away...
