Remove the build platform
To remove the build platform, turn the red knob to the 'unlock' position, then pull the plate toward you until it slides fully off of the build arm.
Remove cured resin
Use the provided print removal tool to scrape off any excess bits of uncured resin from the build platform, careful not to gouge the printing surface. To avoid gouging, slide the print removal tool at a steep angle along the surface of the platform.
Wipe down with IPA
Spray IPA 91% or greater on the build platform, fully saturating the surface. Wait for a few moments to ensure that the IPA has time to break down cured resin. Use a paper towel to wipe away the IPA. Repeat if necessary until platform is clean.
