Are FEP alternatives worth it? ACF vs. nFEP vs. FEP films.

FEP film is widely used as the release layer for DLP, SLA, and LCD 3D printer vats and trays. Some time ago, nFEP was introduced as the better alternative to FEP and promised faster print speeds and a longer life span of the film. But now there is new material on the street with the name ACF. This material is advertised as having “almost no release force” or “long service life” while still having a decent light transmittance of 93%. However, do the increased printing speeds outweigh the significant price increase, and do you really not lose any details by printing with a 300 µm thick film with a mate finish? Let's compare results using ACF vs. nFEP vs. FEP films.
