I just received my 3L and have begun to install the resin tank. Is the film on the bottom supposed to be somewhat opaque or completely transparent?

Hi cfaust,

That translucent-to-opaque profile looks normal.

For handling the film, we advise no direct contact as the photo appears that way, as this can affect the film’s printing quality and to mainly handle it like in our [Replacing the resin tank guidelines](https://support.formlabs.com/s/article/Replacing-the-resin-tank-Form-3L-Form-3BL?language=en_US).

I would make sure to clean the [exterior bottom of the tank](https://support.formlabs.com/s/article/Inspecting-and-cleaning-resin-tanks-Form-3L?language=en_US#clean) if it has not been cleaned yet, since any contamination on the bottom of the tank can affect print quality.
