5.6 Glass
Glass cracks easily, so the laser power should not be
too powerful. Choose thick glass materials for better
flexibility.
5.7 Metal
・
Anodized Aluminum
Anodic treatment is a surface treatment that forms
an oxide layer on the aluminum alloy. Through
laser engraving, the surface oxide layer will be
decomposed.
・
Stainless Steel (with coating)
Due to the wavelength of CO2 lasers, stainless steel
reflects most of the energy, so special oxidants are
needed to allow the stainless steel to oxidize and
darken at relatively low temperatures and darken the
color. Wear work gloves when applying the coating.
5.8 Other Safe Materials
Stone, cement, EVA foam, cotton, linen material, etc.
