Keep watch during operation
● Never leave the Glowforge unit unattended while operating – either when it's paused and ready
to print (with the button flashing) or while it's actually printing (with the button on). Always stay
within sight and look inside frequently.
● A small, candle-like flame where the laser beam strikes the material is normal. This flame
should move with the laser and should not remain lit when the laser has moved past.
● If there is a lasting flame inside the Glowforge unit that does not extinguish when the laser has
moved past:
1. Pull the plug on the back of the unit.
2. If it is safe to do so, extinguish the fire with a wet towel. Note that water may damage
your Glowforge.
3. If that is not an option, then if it is safe to do so, extinguish the fire with a fire
extinguisher. Note that fire extinguishers may cause damage to your Glowforge.
4. If the fire cannot be safely extinguished or if it spreads outside the Glowforge unit,
call your local emergency number (for example 911) and evacuate the building.
5. Do not operate the unit further until you have contacted Glowforge for service

Laser Safety for all Glowforge Printers (except where noted)
Laser Products
The Glowforge Basic 3D Laser Printer and the Glowforge Plus 3D Laser Printer are Class 1 laser
products which contain an embedded Class 4 laser. The Glowforge Pro 3D Laser Printer is a Class 4
laser product. The laser in your Glowforge emits enough infrared light to cause instant skin and eye
injury, or start a fire. This infrared laser light is invisible. The Glowforge unit has a case and glass lid
which block harmful levels of infrared and ultraviolet light to allow you to operate the laser safely.
CAUTION! Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
Do not use if glass or case are damaged or modified.
Any damage or modifications could allow dangerous contact with moving and/or electrical parts, and/or
allow infrared and ultraviolet light, heat, smoke, and fumes to escape.
Safety interlock switches on the front door turn off the laser immediately if they are opened. Do not
place magnets near the lid or doors as they can interfere with the switches. Do not try to defeat the
switches.
