During each layer, the LPU moves across the printer, projecting the laser beam through an anti-reflective coated glass optical window. This window shields the LPU from dust, oil, and resin contamination while maintaining consistent laser accuracy. A dirty or obstructed optical window can reduce print quality, cause layer defects, or lead to failed prints. Regular cleaning helps ensure long-term reliability and consistent results. 👉 Use this guide to learn how to: Identify when the optical window needs cleaning Safely clean the coated glass surface Maintain the LPU for consistent print quality Take our Troubleshooting Resource Survey so that we can make even better resources for you: https://tally.so/r/mK4Rkg ▬ Learn More ▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📄 Optical window cleaning guide: https://bit.ly/4bmiJ25 📕 Explore all Formlabs support resources: https://bit.ly/3Wpbv7X ▬ Music ▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Music track: Marea by Aylex Source: https://freetouse.com/music Free Vlog Music Without Copyright
