Engraving mirrored acrylic is similar to engraving regular acrylic. The idea is to engrave
through the mirrored backing enough to begin to penetrate into the acrylic. Engraving
deeply will cause, a crusty residue to form just like with non-mirrored acrylic. A double
image will appear if engraving on the front side of the mirror. It is not necessary to
mask the backside when engraving because the mirrored backing shields the acrylic
from smoke damage. To cut mirrored acrylic, it might be necessary to remove all
original masking, re-mask with transfer tape, and dampen the tape with water from a
spray bottle. Next, place the acrylic in the laser with the mirrored surface facing
upwards and elevate at least 1/8 inch above the table. The laser beam will not reflect
off of the mirrored surface because it is absorbed by the acrylic first. Sometimes cutting
the acrylic from the back side will cause the mirrored backing to distort and crack from
the intense heat required to cut. If the combination of engraving and cutting is desired,
our suggestion is to engrave the backing, unmasked, remove the acrylic, mask both
sides with transfer tape, flip the acrylic over, dampen, elevate, re-focus, and cut from
the front side. When paint filling the engraved area, make sure to use an acrylic based
paint or paint that does not contain acetone or alcohol as these chemicals will crack the
acrylic. Water based paints also work very well. Since the mirrored backing serves as
a masking, it is not necessary to mask the back side before engraving.
WARNING:
Acrylic is extremely flammable. Do not leave the laser system unattended
when cutting or engraving.
