Wood laser engraves really well and different effects can
be achieved by painting the wood first and very lightly engraving
the painted surface to reveal the wood texture.
MDF and Birch plywood give good results.
Metal cannot be directly laser engraved with a Co2 laser, so the
surface is first painted with a special emulsion paste which, when
dried and lasered gives a very sharp and permanent black image.
Adonised aluminium also engraves well as the different coloured
surfaces reveal the base silver colour through th engraved layer.
Plastics also laser engrave and cut very well, clear acrylic gives
very detailed effect when laser engraved. Also two core acrylics
( these are sheets of coloured acrylic with a very thin different
coloured top layer) the top layer is engraved to reveal the base
colour giving a very detailed image.
Marble, Granite and Ceramic Tiles
All of the above laser engrave with great detail
Photographs can be laser engraved into glass, wood, and plastic.
Ceramic tiles also produce god results when laser engraved. The
best results are achieved from high resolution images with a resolution
of 300DPI and above.
