4.2 WOOD
Types of Wood
• Medium-density Fiberboard (MDF)
MDF is a wood product made by wood fibers and resin
binder formed under high temperature and pressure.
The resin binder has a significant effect on the fume
generated during laser process. Low formaldehyde
MDF is recommended to reduce harmful fumes.
• Plywood
Plywood is made by layers of wood veneer or wood
fiber glued together. Low formaldehyde plywood is
recommended to reduce harmful fumes.
• Solid Wood
Solid wood might have uneven grain when engraved
due to growth rings. The uneven density of wood can
cause such result which is very usual.
Engraving Results on Wood
The slower the speed, the darker the engraved result.
The higher the power, the deeper the cutting depth.
To achieve a darker effect, slowing down the speed is
usually more useful than raising the power.
