Materials must fit
Materials that do not fit properly may obstruct operation and result in damage and increase risk
of fire.
● Materials must be no more than 21 in. wide and must not be so long as to touch the end
of the Glowforge unit. Material must be less than ½ in. tall if the crumb tray is in, or less
than 2 in. tall if it is removed.
● Materials must not extend past the side of the crumb tray (if it is being used) or the metal
bottom of the print area (if not).
● Do not place rolled-up material in the Glowforge. It may be too tall, or unroll during
printing, obstructing operation.
Materials must be flat
● Materials must be flat so they rest on the crumb tray.
● While a bulge is acceptable, for example from warped wood, the highest point of the
material may not extend more than ½ in. above the crumb tray.
● Material must never double back on itself, for example curling up.
● Should material curl or bend so it reaches more than ½ in. above the crumb tray during a
print, turn off the power immediately.
● If the material has a protective paper or plastic coating, that coating must be firmly
affixed to the material. If it begins to peel off, discard the material and do not print on it.
Operating Environment
To prolong the life of your Glowforge unit and to reduce the risk of fire or mechanical failure, do
not put the Glowforge unit where it could experience:
● Extreme temperature or humidity
○ Temperatures below 40 degrees Fahrenheit (5 Celsius) or over 120 degrees
Fahrenheit (48 Celsius)
○ Extreme humidity conditions (below 10% or more than 75%)
○ If venting outdoors, ensure that changing conditions do not cause extreme
temperatures or humidity to enter the Glowforge unit through the exhaust hose.
Disconnect the hose from the outside air when the Glowforge is not in use.
● Direct sunlight
● Rain, moisture, or liquids
● Excessive hair, dust, or small particles
● Loose materials such as paper or a tablecloth that could be sucked into the air intake on
the bottom of the Glowforge
