Checking the Form 1+ Mirror


Exercise extreme caution when the mirror is exposed. Contact Customer Support before you clean your mirror or if you have any questions.

The Form 1+ uses precision laser optics that may need special attention from time to time. The mirrors in the Form 1+ optical system, called first surface mirrors, require special care different from conventional mirrors you might find around the house. To check your mirror for dust or resin spills, follow these steps:

1. Remove the build platform and resin tank

2. Check the mirror for dust and resin

Without the right lighting, some dust or oils on the mirror may be impossible to see. Move your light source around to inspect the mirror at various angles.


Compressed air can cause damage to the mirror if used improperly. To use canned air, bend the straw while holding the can upright. Tilting the canister will expel liquid and will permanently damage the mirror.
