Choosing a material: what engraves well and what fights back

A laser does not cut every material the same way, and the difference shows up in contrast. Anodised aluminium is the easy win: the beam bleaches the dye and you get crisp white-on-black with no consumables and no variation between pieces.

Wood is the opposite — beautiful, but every board is different. Grain density changes how deep the burn goes, so two plaques from the same species can come out at noticeably different tones. If you need fifty identical pieces, budget for a few extra blanks.

Clear acrylic engraves to a frosted white and looks excellent lit from the edge. Cast acrylic frosts more evenly than extruded; if a supplier will not tell you which one you are buying, assume extruded.

Powder-coated steel behaves like anodised aluminium but is less forgiving of a beam that is slightly out of focus. Send us the actual item where you can — we would rather test on the real thing than on a sample that only resembles it.
