Laser Safety

All Glowforge Printers
The Glowforge Basic 3D Laser Printer is a Class 1 laser product containing an embedded Class
4 laser and 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.
Do not modify or service
CAUTION​ ! Attempting to modify or service the Glowforge unit may result in hazardous laser
light exposure.
To reduce the risk of injury:
● Do not attempt service. All service must be performed only by the Glowforge factory or
by factory-authorized technicians.
● Do not attempt to alter or modify the unit.
● Only use the front door or top lid to open the case. Do not try to open the case any other
way, such as by drilling holes, removing fasteners, or removing coverings.
● Do not try to disassemble or open sealed portions of the Glowforge unit, including any
protective coverings or housings.
● If the crumb tray is removed, use extreme caution to ensure that the laser only strikes
laser-compatible material, and does not touch the metal bottom of the unit which could
cause a reflection and damage the unit.
