Hey there @orwo! 25 Micron Castable Wax V1 setting are available on the Form 3. They just require a specific firmware iteration. You can get more detail at the link below(check just below the table showing the resins).

Here are links to the Preform Jewelry Beta and the matching firmware: -JD > [@Preform Jewelry Beta 25 micron prints](http://forum.formlabs.com/t/preform-jewelry-beta-25-micron-prints/25805): > > With some help from the FormLabs Support Staff, I’ve managed to roll back the firmware on my Form3 to the proper version to allow 25 micron printing of Castable Wax resin using the Preform 3.1.2 Jewelry Beta.
