Chroma range — Choose PLA if…

You want colour The pigments are mixed into the filament itself, so the colour lasts.
You want relief Four thicknesses, from 5 to 20 mm, for a slim or a sculptural word.
The room is damp PLA is not affected by water: it suits a bathroom or a kitchen, away from heat sources.
You want a healthy material PLA gives off no hazardous volatile organic compounds (VOCs), neither when printed nor on your wall.

Wood range — Choose wood if…

You love natural materials Lime wood has a fine grain with no knots, from creamy white to very pale blond.
You want to customise it Lime wood takes acrylic paint, stain, varnish or wax very well.
You want a flat letter At 3 mm thick, the letter stays discreet and graphic on the wall.
You like contrast The laser seals the edge and outlines every contour with a thin golden-brown line.

FAQ — Your questions about materials

Which material for a bathroom?

PLA. It is not affected by water, but keep it away from heat sources and full sun. Lime wood is for dry rooms only, unless you apply a water-repellent varnish first.

Do PLA letters fade?

PLA is coloured through and does not fade over time. Just avoid prolonged exposure to intense UV, which can dull the colours.

Do wooden letters have burn marks?

Laser cutting seals the edge, which takes on a golden-brown shade. The front of every piece is sanded: the line only remains on the contours.
