Exhaust
Only operate your Glowforge unit when it is exhausted to the outdoors or through the Glowforge Air
Filter. Failure to exhaust will cause smoke and fumes to escape into the room, presenting a risk of
health hazards or death.
If you exhaust outdoors, be sure that the exhaust location won't be bothersome to neighbors or
passers-by, and don't forget to check your local rules for air quality regulations that may apply to you.
To prevent smoke and fumes from escaping the unit, do not open the lid until the fans stop.
Follow all of the instructions in "Setting Up" carefully.
There may be some odor present while printing. However, if you detect a strong, sharp smell that also
causes eyes, nose, or throat irritation, or if there is visible smoke escaping while the lid is closed, stop
immediately and re-check your exhaust setup. If the irritation and/or smoke emissions do not abate,
discontinue using your Glowforge and contact support.
Pro Users: There may be small openings around the edges of the passthrough slot. This is expected;
your Glowforge Pro's powerful fans will whisk smoke and fumes away into the exhaust hose.
Safety Equipment
Be sure carbon monoxide detectors are installed and tested in the building as recommended by local
codes and manufacturer recommendations.
Materials Safety
Laser-Compatible Materials
"Laser-compatible" refers to materials that can be safely processed with the CO2 laser in the Glowforge
unit. Materials that are not laser-compatible may catch fire, emit hazardous smoke and fumes that
cannot be controlled by exhaust or filtration, and are a health hazard to you, your neighbors, and your
Glowforge printer. For this reason, you must only put laser-compatible materials in the Glowforge unit.
Proofgrade™ materials
Glowforge sells a line of Proofgrade materials that are laser-compatible and give top-quality results
when used with the Glowforge printer. To learn more about Proofgrade materials, go to
