Dlp print error

The printer is the AnyCubic Photon, the slicer is any cubic as well, although I use ChiTuBox as well.  The preview was normal.  This is not the first time this has happened.  i did another set of model car tires, printed flat, and two of them had protruding layers.  The layers stick out in line with the tread pattern on the tires.

I too have an Anycubic Photon, and use Photon slicer and ChiTuBox.  I haven't seen this before.  It's almost like those problem areas have become 'adrift' or 'unstuck' during the printing process.

I can think of a few suggestions:
1. As Carl said, check your layer times...it seems opaque resin takes a bit longer layer curing time than the transparent green that came with the printer. Photon slicer's default exposure settings are different than ChiTuBox's default settings.
2. Ensure your build surface is level.  Follow the manual's instructions...don't take shortcuts or invent your own procedure.  When you adjust the leveling, you may need to readjust your Z=0 setting.  Remember that 'home' and 'zero' are two different things.
3. Check that your film is taut in the tray.  If the film has stretched for any reason (e.g. prints sticking to the film, failed prints, solidified resin in the bottom), you may need to tighten the screws around the perimeter at the bottom of the tray. You don't have to remove the film, just tighten the screws.
4. Make sure your film and LCD screen are clean, especially in the affected areas.  Don't wipe the film with paper towels, as it will eventually graze the film.  I use Sprayway glass cleaner. It's ammonia-free, and contains alcohol which helps clean the resin.  I dab the film dry with a paper towel or cotton ball, then wipe it with a microfiber cloth...so far, so good. 

If you need to replace your film, a spare one came with the printer.  Additional film can be purchased from other sources at 1/4 the cost of AnyCubic film.
