Have you post-cured the prints? As in, hung them in a UV-light chamber? The haze is air-cured resin.

@Trish I think you got it, this was not chamber-cured. The [previous print](https://twitter.com/0xF2/status/1302634555136974848) was and does not show the whitening. How does one complete curing the surface so that it retains a wet, translucent look? There must be an oil or paint coat selection.

Also, if you want to write it up as an answer, so I can accept it. I assume the sequence is 1. IPA wash 2. UV curing. 3. whaterver finishing. 4. Done!

Looks like Step 3 is a pass of clearcoat. Formlabs has a nice [guide](https://formlabs.com/blog/3d-printing-transparent-parts-techniques-for-finishing-clear-resin/) to transparent printing that should apply.

As you can see this "hazy glaze" is almost as white as the underlying sheet of Scott paper.

How does one cure a transparent resin print to finish the best look for transparency?
